How to Test Everything on Your Dashboard with One Click

Modern cars have such a function as self-diagnosis of instruments on the panel. It allows you to understand many important points, including which device has failed. It is especially important to check the panel in this way if you decide to purchase a used car. After all, a non-working device can lead to not the most pleasant consequences.

To run automatic device testing, you need to perform a certain series of actions. Photo: drive2.ru

Check or auto test of the Lada Vesta dashboard

During the operation of the car, minor troubles may occur in the instrument cluster. For example, the odometer needle, coolant temperature or fuel level does not indicate the correct value, or the speedometer does not work. In this case, the manufacturer has provided automatic diagnostics of the instrument panel.

Light indication

When the self-test mode is activated, the fault code can be determined by the flashing indicator M1 (red light in the center of the instrument panel). The number of flashes is a four-digit code number.

Number of flashes

The transition from one code digit to another occurs at intervals of 1 second, during which time the light does not light up. It takes 1.8 seconds to move from one four-digit code number to another. At this moment the lamp is also extinguished. A repeated code of four zeros means that there are no faults.

Diagnostic connector

For most Renault Megane models, the connector for connecting external test devices is located between the car radio panel and the AUX input on the center console. The connection device is hidden by a decorative plastic cover. To remove it, use a durable plastic hook-shaped device. The device must be inserted into the hole and pulled towards you sequentially, first one edge of the lid, and then the other. The fixing clips are on the left and right.

Priora car on-board computer: functions

In fact, the device only transmits the data owned by the electronic control unit. Therefore, all bookmakers for Priora broadcast the same data. Everything interacts: ECU, voice, oscilloscope. The display shows the following data as standard:

• navigation, router;
• watch with date display;
• average fuel consumption per hour/per point in time;
• total/daily mileage;
• remaining fuel (+ how many kilometers you can still travel);
• voltmeter;
• engine operating time;
• ambient/antifreeze temperature;
• precise speed (digital speedometer), average speed;
• acceleration to 100 km/h (time);
• digital odometer.

Additionally, he can report on maintenance based on mileage - changing oil, filters, spark plugs, belts. In addition to counting the mileage to these checkpoints, it displays information from all sensors when the driver enters a certain tab. There is one thoughtful function - it can warn that the lights are not turned off after turning off the ignition.

Instrument testing

To get the most complete picture of the performance and malfunctions of Renault Megane systems, you should use a special device. Devices can be both digital and analog. The testing system must support the OBD 2 standard diagnostic protocol.

The automaker itself recommends only one device for this: the CLIP device. The device can be connected to a laptop or any mobile device, provided the latter has the appropriate software. There are special programs for diagnostics.

The most common utility for self-scanning by car enthusiasts is DDT2000. But it is not able to provide complete information. More complete information is provided by Renault CAN Clip V-80 and Renault Clip V-93. A significant disadvantage of many versions of the software is the original French language. The CAN Clip licensed program costs more than 50 thousand rubles.

Deciphering faults in the fuel and air systems

• P0030 - the oxygen sensor heater wire to the exhaust gas converter has broken;
• P0031 - the same electrical wire has shorted to ground;
• P0032 - the same wire has shorted to the on-board network (BS);
• P0036 - the wiring of the oxygen sensor heater is broken, after the converter;
• P0037 - the same wiring has shorted to ground;
• P0038 - it has shorted to BS;
• P0102 - weak signal in the mass air flow sensor network;
• P0103 - very strong signal in the network of this device;
• P0112 - weak signal in the air temperature sensor network;
• P0113 - very strong signal in the network of the same device;
• P0116 - antifreeze temperature sensor signal is out of operating range;
• P0117 - poor signal from the antifreeze temperature sensor network;
• P0118 - very strong signal from the antifreeze temperature sensor;

The process of diagnosing a car using a tester or a connected computer

Much more accurate and reliable data when checking a car for malfunctions can be obtained if you use separately connected equipment. But the introduction of such tools and devices gives encrypted readings, therefore, in order to correctly understand and find all the faults in the car, you need to decrypt the data received from diagnostic devices. Of course, manufacturers could have done things easier for Russian-speaking car enthusiasts. It would be possible to write “replace the canister valve” on the device screen after diagnostics, but instead, only a code in the form of p0441 can be found on the display, and code p0130 will appear only due to problems with the oxygen sensor.
