How to diagnose a 16-valve priors engine yourself

Priora connector

The main diagnostic connectors are OBD connectors. On earlier VAZ models, such as 2110, the OBD-1 connector was used. Currently, the most popular connector, which is used in all modern Lada models - OBD-2, has also been abandoned.

This diagnostic block in the Priora is located behind the glove box compartment; the scanner is connected to it.

Rough road sensor - replacement

The rough road sensor is mounted on a bracket and attached to the right mudguard of the body.

Removal

1. We prepare the car for work.

2. Squeezing the loops of the latch, disconnect the wiring harness block from the sensor.

3. Using a Phillips screwdriver, unscrew the two screws securing the rough road sensor to the bracket and remove the sensor.

Installation

Install the sensor in reverse order.

Diagnostics

Priora diagnostics can be carried out at any service station. This allows you to identify problems with the engine, namely the culprit of the problem. It will help save money, time and effort to find the cause yourself or at random.

Such engine scanning at a service station is carried out with an expensive and advanced scanner, which is quite expensive. Checking the Priora ECU for errors in a specialized service will cost from 1000 rubles and more.

Which adapter to choose for VAZ

Before you buy a scanner for diagnostics, you need to find out which control unit is installed on your vehicle. Most models are equipped with control units with a K-line for data exchange. Therefore, the best choice is a VAGCOM diagnostic cable or an improved version of the K-Line diagnostic adapter. These adapters are suitable for diagnosing VAZ vehicles and ensure correct coordination of the vehicle's diagnostic system and computer. Please note that you will be able to perform full computer diagnostics, just like specialists at a service station.

Diagnostics with ELM-327 scanner

Thanks to Chinese engineers, car diagnostics have become much easier and cheaper. Not long ago, a universal internal combustion engine scanner appeared on Chinese websites, which is suitable for almost all cars with OBD-2 connectors.

The ELM 327 scanner on the AliExpress website costs from 5 to 10 dollars, depending on the version.

This gadget is divided into two types and you should pay special attention to this when purchasing. ELM 327 works with our domestic cars only on version 1.5. Therefore, you need to purchase an ELM-327 v1.5 scanner. If you purchase version 2.1, then work with domestic cars is not guaranteed.

It should also be noted that this scanner only works in conjunction with a smartphone. If you have an Android smartphone, then you just need to buy a scanner with Bluetooth only.

If your smartphone is based on iOS, then you need to purchase a scanner with a Wi-Fi module, since Apple smartphones do not allow connecting third-party devices via Bluetooth.

Troubleshooting

Note! If you are unsure of your own abilities, the motorist is strongly recommended to seek help from a specialized workshop or a qualified technician.

If you have the necessary equipment, you can determine whether 8 or 16 valves are broken in a Lada Priora car yourself. Due to the simple design of the machine, repairs do not require the user to have in-depth knowledge of mechanics, electronics or other sciences.

Today I tested it, it works, the connection is stable. If there is an error, then the software writes the number and transcript.

To solve the issue, you need !

1. Smartphone, Tablet for Android v4,5,6.7 2. Bluetooth adapter ELM 327 bluetooth-elm327 />3. OpenDiag software

With the purchase of this adapter, there is no need to install such things as the State on-board computer. The adapter is in the glove compartment, the pipe is always with you!

pinout, electrical package control controller and circuit

Almost all modern cars today are equipped with electric windows, which allow you to control the opening of the windows at the touch of a button. And the Russian Priors in this case are no exception. The control device, with the help of which the windows are raised and lowered, as well as many other functions, is called the Priora comfort unit. You can learn more about its structure, as well as repair, from this article.

Description of the electrical package control unit

The electrical package controller in Priora is a device used to control the functionality of the vehicle. This unit is responsible for the operation of turn signals, power windows, control panel lighting, dimensions, fog lights, interior lighting, and rear window heating system. This device also ensures the normal operation of the reversing lights. The fact that the car is equipped with this device makes it even more practical.

Location

The control device on the Priora is located above the electronic engine control unit, at the bottom of the center console, in the middle. In this case, the device is connected using two connectors - power and information. The power output is used to supply voltage to the control unit, and the information output is used to perform the functions of the device. It should also be noted that the control unit is protected from external influences of dirt and moisture.

In general, this device is a circuit installed in a plastic case. The board itself includes 15 chips, each of them performing certain functions. This is the entire electrical part of the car, including power windows, door open sensors and a control system for external electric mirrors (the author of the video is the CompsMaster channel).

terms of Use

In order for the node to operate normally, certain conditions must be met:

• the air temperature level in the car interior should be from -45 to +40 degrees;
• the air humidity level in the cabin should be no more than 90%;
• The voltage parameter for normal operation should vary around 9-15 volts;
• The atmospheric pressure level should be up to 800 mm Hg.

As practice shows, malfunctions in the operation of this device often appear as a result of its overheating or disconnection of wires or contacts inside the structure. If you are faced with the problem of a device failure, first of all you need to visually diagnose it. It is quite possible that the reason can be discovered only by looking at the device.

Photo gallery “Connection diagram and designation of controller board elements”

Possible malfunctions and ways to eliminate them

What malfunctions may occur in the operation of the electrical package controller:

1. Turn signal failure. First of all, you need to diagnose the serviceability of the fuse, light bulbs, and the steering column switch. It is quite possible that the contact in the switch itself is broken; the problem can be solved by resoldering the contacts or replacing it. If this does not help and the problem really lies in the board, then there are two options - either resoldering it in accordance with the diagram, or replacing it. Usually, soldering is done first, and if it does not help, then the controller itself is changed.

Video “Diagnostics of the electrical package control controller”

How to diagnose the functionality of the electrical package controller in a garage environment - see the video below (the author of the video is Vyacheslav Kravchenko).

An example of diagnostics using the ELM327 scanner

Below is an example of diagnosing a car with a scanner from AliExpress on version 1.5 using an Android phone and the OpenDiag application on a Lada Priora.

All manipulations with scanning the ECU must be carried out with the engine running or with the ignition on.

We connect the scanner to the OBD-2 connector and wait until the indicators blink.

Next, go to Settings/Bluetooth on your phone. There we find OBD II and pair it with it. When pairing, the device will ask for a password code - 1234 , this code is the same for all scanners.

The next step is to go to the OpenDiag application. Click on the menu button, select the connection type and check the Bluetooth ELM box.

Next, click on the button in the upper right corner and select our device, in this case OBD II. After this the connection will occur.

The connection process is complete, then you can speed up the application itself and familiarize yourself with its functions.

How to fix the problem

There are several possible ways to resolve this issue. If one solution does not suit you, move on to the next one. We will also look at what to do if none of the options for eliminating error 4 helps.

Method No. 1 (Software update)

Trying to find out what the essence of the problem might be, many initially undertake to analyze the correct operation of the receiver and its unique ID (as a rule, it is already present on the access card, and if there is no smart card, it is integrated into the system itself). Here it becomes clear that the receiver is not able to recognize its own ID number, which, in turn, makes subsequent decoding of the channel impossible. Accordingly, if error number 4 appears, then you should understand the features of ID recovery.

1. If error 4 appears on tricolor TV, you need to go to channel 333. This channel is specially designed for performing service actions. It is after the transition to it that the procedure for updating the standard software is carried out.
2. Then check for updates. The receiver will do this on its own. When a new software version is detected, it will prompt the user to confirm the installation. After completing this action, error 4 tricolor should disappear.

What to do next? After the receiver accepts consent, it will initially carry out the installation from the satellite, and then, after reaching the 50% mark on the progress scale, it will begin installing the downloaded files into the device’s memory. This will continue until the progress bar is filled to 100 percent.

Note! If you are connected to a satellite and you have approved the installation of the updated version, do not turn off the receiver under any circumstances! Otherwise, you will not be able to completely fix the problem. In some cases, the receiver no longer displays channels due to insufficient files in the software package or due to their corruption

After all the necessary files have been downloaded and installed, the receiver will reboot itself for the updated files to take effect. After a reboot, the system should completely resolve the problem.

In the case of some models, installation of a software update for the module is additionally required. Remember that its update occurs immediately after the main firmware is loaded into the system. The module updates much faster. Mandatory installation of these files is not always required - much depends on the behavior of the system after the main firmware update is completed. If error 4 disappears, we don’t touch anything else. When saving it, we try to additionally update the module.

Important! Sometimes a software update may not help, since there is a USB flash drive in the slot. Remove it and reboot the receiver, it should help

Method number 2 (Reset settings)

Sometimes eliminating the fourth error requires resetting the receiver to factory settings and searching for channels again. This is done very simply:

1. Press the "Menu" button on your receiver's remote control.
2. Select "Settings".
3. Then scroll to the very end to the “About the receiver” section, “Reset settings”.

After you reset to standard settings, search for Tricolor TV channels again, and in order to watch channels with a broadcast shift relative to Moscow of +2 (+3) hours, select the “Ural” region.

Method number 3 (Contact support)

If the previous two methods of solving the problem did not help you, then you can contact Tricolor technical support. But before you call, collect the following information:

• ID number of the smart card;
• The number of your agreement with the Tricolor company;

Types of equipment used to check LADA

A list of diagnostic devices used not only in specialized car services, but independently, for example, in a garage. • Odometer correctors, with setting mileage values; • Models that support protocols, by reading information, erasing errors, codes are deciphered: ELM327 USB / Bluetooth / Wi-Fi running on the elm327 chip; • Vag adapter (cable) for later versions of the ECU and 12 pin pads; • Testers whose work is organized on the basis of oscilloscopes.

Diagnostic devices that support combination with ABS and SRS units, as well as using a CAN bus, are in demand.

Modern popular models

The best diagnostic scanners compatible with the VAZ have been selected for review. We pay attention to the following samples:

How to use

Before purchasing an adapter, make sure it is compatible with your car. After purchasing the adapter, it is important to correctly connect the scanner to the connector. As a rule, the OBD 2 connector is located in the passenger compartment under the dashboard. Models before 2006 usually have a 12 pin connector (GM), and to connect the scanner you will need a 16 pin adapter.

Information on the location of the connectors is presented in the table and photo below.

Decoding codes

Well, if you succeed in checking your car for faults, then you need to decipher the combinations of errors, otherwise why do you need diagnostics at all?

Self-diagnosis

Let's look at the decoding of combinations of faults that you can read when checking the Lada Priora yourself.

For diagnostics and error resetting, I am considering this option for the LAUNCH Creader VI scanner, it costs from $100. USA. motorstate.com.ua/item/LAUNCH-CREADER-VI It seems to me a serious alternative)) Yes, it is completely Russified.,

It all depends on the ECU.

If only for diagnostics, then take ELM and not necessarily with bluetooth, the free OpenDiag program works great with the cable.

In short, should you take the “Mini ELM327 OBD2 OBDII V1.5 Bluetooth Diagnostic Interface Scanner”?

On older K-LINE priors, the CAN bus (ELM adapter) also works fully. On the new Priors, K-LINE was removed and only CAN was left. so only ELM will do. In general, you can look at what kind of ECU it is and go from there.

As for ELM, you’re unlikely to find free, adequate software for Windows. So if you take ELM, then only bluetooth to connect to a tablet or phone.

Priora norm 2012 with abs, power steering, e gas, some kind of Bosch)

buy a regular k-line adapter with auto-connect. I’ve been working with it for a year now and can connect to everyone without any problems.

Like any modern car, the Lada Priora is equipped with dozens of various sensors, the functioning of which determines the condition of the main vehicle systems. Diagnostics of the machine for errors allows you to detect all sensor faults in order to eliminate breakdowns. Now you will learn how Priora error codes are deciphered and how to independently diagnose the on-board computer (hereinafter referred to as BC).

Location

Often faced with a problem where the diagnostic connector is located. In each car they are installed differently, taking into account the specifics of the entire structure. As for Prior, everything here is done quite cleverly. If you don't know the exact location, it will be difficult to find.

Car manufacturers have placed a diagnostic connector in the glove box. You can find it on the passenger side in the interior. Simply put, look in the glove compartment. If you contact service centers, specialists will immediately find the required design. Beginners need to be more vigilant in this matter.

It is best to work according to already compiled instructions. Let's take a closer look at the process:

1. We completely open the glove box and clear it of foreign objects to make it easier to work.
2. The glove compartment should hang on plastic guides on each side.
3. We press on the side plates so that the small door opens further. This will make it easier to work and find the Priora diagnostic connector.
4. We pull out the tabs on the side and completely remove the glove box from the latches.
5. Provides access to the input plug for diagnostics. Now he is free and ready to go.

Access to the device is open. The following operations directly depend on the purpose of “opening” your car. More often they get to the connector to reconnect it or check the correct signals from the ECU. This way his work will be adjusted and will not create problems or unforeseen situations.

Video “Control unit error 1602”

In this video, the author talks about the power failure error on the ECU of a VAZ Priora car.

To check instrument panel error codes, you need to enable test mode. To do this, you need to press the daily mileage reset button and, without releasing it, turn on the ignition. All familiar positions should light up on the liquid crystal display (LCD), and the arrows of the tachometer, speedometer, coolant temperature indicator and fuel level indicator should move from minimum to maximum values ​​and back. The serviceability of the LCD and the above sensors is visually checked.

Press any key to switch functions of the on-board computer (BC). The program version is displayed on the LCD.

Press the BC function switch button again. The LCD should display (if present) the following error codes:

2 – increase the voltage of the on-board network,

3 – fuel level sensor error*,

4 – coolant temperature sensor error*,

5 – error of the external temperature sensor (if there is no sensor reading within 20 seconds, indication on the LCD is “-C”),

6 – engine overheating**,

7 – emergency oil pressure**,

8 – brake system defect**,

9 – battery is discharged**,

E – detection of an error in a data packet stored in EEPROM.

*- if an open circuit of the sensor is detected within 20 seconds

**- the criterion for triggering the acoustic alarm is met

If necessary, you can reset error information. To do this, press and hold down the daily mileage reset button for 3 seconds.

The next time you press any of the BC control buttons, all familiar positions should light up on the LCD - the system has returned to its initial state.

If you do not press any control buttons for approximately 30 seconds, the instrument panel enters the operating state.

Decoding error codes and criteria for their occurrence

Checking Dashboard Error Codes

1. Starting position: ignition off, battery on. 2. While holding down the daily mileage reset button, turn on the ignition. All positions of familiarity areas (segments) should light up on the LCD, which indicates the start of self-testing. 3. Press any of the on-board computer control buttons. The LCD should display the program version (Ver 1.0 and higher). 4. Press any of the control buttons again. The following error codes (if any) should be displayed on the positions of the first and second lines of the LCD:

2 Excessive voltage 3 Fuel level sensor error* 4 Coolant temperature sensor error* 5 Outside temperature sensor error** 6 Engine overheat*** 7 Emergency oil pressure*** 8 Brake defect*** 9 Battery low*** E Recognition errors in the data packet stored in the EEPROM

Note: * – an error is registered if within 20 seconds. a sensor break is detected; ** – an error is registered if within 20 seconds. The actual sensor data is not recognized (indication on the LCD is “— °C”); *** – accompanied by an acoustic signaling device.

1. Acoustic alarms. All acoustic indicators are displayed only when the ignition is turned on and if certain criteria are met. If several criteria are active in parallel, the alarms should be displayed in the sequence of their arrival one after another with a pause of 1.5 to 2.5 seconds. 2. Engine overheating. Criteria: coolant temperature display ≥ 115°C. Alarm: constant sound for 5 seconds. Termination: The coolant temperature gauge drops to ≤ 110°C. Repetition: The coolant temperature gauge drops to ≤ 110°C, then rises again to ≥ 115°C. 3. Emergency oil pressure. Criteria: engine speed ≥1000 rpm; The “oil pressure” input is active for 10 seconds. Alarm: constant sound for 5 seconds. Termination: Oil pressure input not active or speed ≤ 900 rpm. Repetition: Oil pressure input active, speed dropped to ≤ 900 rpm and then increased again within 10 sec. ≥ 1000 rpm. 4. Brake defect (front brake pad wear indicator). Criterion: the “brake defect” input is active for 10 seconds. Alarm: 0.5 sec on/0.5 sec off 5 repetitions. Abort: Brake defect input is not active. Repetition: “Brake defect” input active for 10 sec. 5. Low batteries. Criteria: speed ≥ 1000 rpm, “battery” input active for 60 seconds. Alarm: 0.5 sec on/0.5 sec off. 5 reps. Termination: Battery input not active or speed ≤ 900 rpm. Repetition: The battery input is active and the speed has dropped to ≤ 900 rpm and then increased again within ≥ 60 sec to ≥ 1000 rpm. 6. Seat belts are not fastened when the ignition is turned on. Criteria: Ignition on, seat belts not (yet) fastened. Alarm: 0.5 sec on/0.25 sec off/0.25 sec on/0.25 sec off, 5 repetitions. 7. Fuel reserve. Criterion: the fuel reserve indicator is turned on. Alarm: 0.25 sec on/0.25 sec off, 2 repetitions.

Coolant temperature sensor - removal, check, installation

To complete the work you will need:

— multimeter (in voltmeter mode, ohmmeter with a measurement limit from 100 Ohm to YukOhm);

— thermometer (with a change limit of at least 100 °C);

- a small heat-resistant container with a volume of about 0.5 liters for water;

- about 0.3 liters of water, heated to boiling temperature.

The thermometer can be replaced with a digital multimeter with thermometer mode.

Removal and inspection

1. Drain the coolant.

2. Remove the air filter housing.

3. Release the clamp of the wiring harness block and disconnect the block from the sensor.

4. Connect the negative probe of the engine voltage.

5. Turning on the ignition, use a voltmeter to measure the voltage at terminal A of the wiring harness block (the terminal designations are marked on the wiring harness block).

Comment

The voltage at the terminal must be at least 12 V. If the voltage does not flow to the block or it is less than 12 V, it means that the battery is discharged, the power circuit is faulty, or the ECU is faulty.

Warning!

When the voltage measurement is complete, turn off the ignition.

6. Using a 19 mm spanner, unscrew the temperature sensor and remove it from the thermostat housing. The connection between the sensor and the thermostat is sealed with a copper washer.

7. Connect an ohmmeter to the sensor terminals.

8. Fill the container with boiling water, immerse the working part of the sensor in water and record the readings of the device at a temperature of about 100 °C. As the water cools, we measure the resistance of the sensor at temperatures of 90, 80, 70, 60, 50, 45, 40, 35, 30, 25 and 20 °C.

If conditions permit, readings can be taken at a lower temperature. The resistance of a working sensor should be close to the data specified in Table 9.2.3.

We replace the faulty sensor.

Installation

1. Install the sensor in reverse order.

2. Fill the engine cooling system with liquid.

3. Start the engine and make sure there are no coolant leaks from under the sensor. If necessary, tighten the sensor into the thermostat housing.

Recommendation

If the leak cannot be eliminated in this way, you should reinstall the sensor by applying a heat-resistant sealant to its threaded part, or replace the copper washer.

Lada Priora does not start: possible reasons

Cars November 10, 2016

"Lada Priora" is a popular Russian car that is loved by many. Overall this is a good car. But sometimes it happens that the Priora does not start.

Owners of both new cars and vehicles with good mileage may encounter this. There are a number of reasons for this “behavior” that need to be considered.

This information will be very useful for novice drivers.

Why won't the engine start?

In order for the engine to start successfully, four conditions must be met.

These are a sufficient crankshaft speed, a good level of compression, sufficient battery voltage, as well as the composition of the fuel mixture.

Therefore, if a Priora car does not start, we can assume that some of the conditions are not met. To check this, you should analyze the situation.

If the unit does not want to start, then the first thing that is usually checked is the starter, battery, and high-voltage wires.

Is the starter working normally, are there any suspicious sounds during its operation? Have the starter or battery been replaced? If the latter is discharged, then check the generator to see how well it charges the battery.

Or maybe there are some problems in the electrical part? If you answer these questions, you can easily find out where the problem lies.

Starting the Priora engine and battery

What happens when a warrior turns the key in the ignition and tries to start the engine? The starter starts and turns the crankshaft. If there is no reaction to turning the key, then look at the battery charge level. Most starters will not operate if the voltage drops below 10 volts.

However, low voltages do not necessarily indicate problems with the battery. The battery could simply be discharged due to long attempts to start the car. The generator is also often to blame for insufficient charge.

If not, and there are similar symptoms, then experts recommend charging the battery and trying again after a while. This is often followed by attempts to start the power unit using a working battery or charging equipment.

When the car starts and drives, then it should be assumed that the battery is discharged or faulty. If the battery accepts charging current and passes all tests, then check the efficiency on the charger.

Video on the topic

Generator testing

A properly functioning car alternator produces approximately 14 volts at idle speed with all electrical equipment turned off. At the time of the first start, the voltage should increase quickly - it will be 2 V or more. Then the current increase gradually decreases and levels off.

This value will change depending on how charged the battery is, how much load is being placed on the bot network, and the temperature. The smaller it is, the higher the charge voltage. The charging current from a standard Priora generator can vary from 12.9 V to 14.8 V in frosty weather.

If the generator does not produce the required voltage, most likely the Priora will not start because of it. But there may also be a breakdown in the current regulator. To check whether the generator is working correctly, it is connected bypassing the regulator. You can also conduct bench tests at a service station.

If the voltage on the generator increases, it is necessary to replace the regulator relay. Sometimes fluctuations occur if there is a problem with the ECU. If the output voltage level does not change, the generator must be replaced. The device has a rectifier unit - one or several diodes in it regularly fail.

At the same time, the generator power decreases. It will also generate voltage. However, it will not be enough to fully charge the battery.

Hello. The Priora won't start. The starter turns. Is it possible to read errors using elm327 only when the ignition is on?

no only with it on

I understand that you have it constantly connected?! It just sticks out there in the plug, but the glove compartment closes properly?

why constantly, no, when there is a need then I connect

I practiced on three Open Diagram machines today! Showed only one truth! At four stationary speed the speed showed 67 km/h, the mains voltage was 7 volts. On the Priora the injection time was 78 ms. Does anyone know what is the reason for the incorrect readings?

Question for software developers. Make screenshots of the survey in OpenDiag too. THE RESULTS ARE MANDATORY FOR PUBLIC VIEW.

Where's the fuel consumption?

He exists, he cannot but exist!

Average? Or current

Install and see everything!

So I’m wondering if it’s worth it) otherwise when something is not on the screen you remember the old

The best advice is to try it yourself and post your results!

Hello, is it possible to use opendiag to make all doors open at once using the remote control?)

Will it work on Android?

Hello, is it possible to use opendiag to make all doors open at once using the remote control?)

But it doesn’t work with the standard key, or what? it seems simple there.

I have a switchgear))) only for diagnostics)) I went to different specialists twice, they said the comfort unit is being repaired)) it does not record the ban on separate door unlocking))

I also bought a 327 adapter. I tried a bunch of programs for Android and couldn’t find one that worked properly. And I think using a mobile phone as a BC is tantamount to feeding a pig pineapples) And BC is still more convenient than an adapter-phone bundle. By the way, for a neighbor on a grant, plugging the adapter into the connector turns off the electric power steering.
