When starting the engine by pressing the start button «start»
The OBD warning light comes on for about 3 seconds and then goes out.
In the event of a malfunction in the injection system (1st degree of severity)
Written message is displayed «Injection a controle» (check injection system), accompanied by the turning on of the signal lamp «Service». This indicates a decrease in the level of safety and the need to use the engine in «sparing» mode.
These faults may be caused by:
- malfunction of the throttle valve with a servo;
- malfunction of the accelerator pedal position sensor;
- absolute pressure sensor malfunction;
- ECU malfunction;
- malfunctions in the power supply circuits of actuators;
- malfunctions in the power supply circuit of the computer.
In the event of a serious malfunction of the injection system (2nd degree of severity)
The red engine symbol and the message are displayed «Stop» (only on matrix display), and a written message appears «Mjection defaillante» (injection system is faulty), accompanied by the warning light «Stop» and sound signal.
When the engine overheats
Engine temperature alarm symbol appears (only on matrix display) with written communication «Surchauffe moteur» (engine overheating), accompanied by the warning light «Stop» and sound signal.
If a malfunction is detected that leads to an excess of exhaust gas toxicity standards
The OBD warning light comes on with the engine symbol:
- «flashing light» in case of a malfunction that can lead to the destruction of the catalytic converter (misfires of the mixture leading to its destruction). In this case, stop driving immediately.
- «constant light» in case of exceeding the norms of toxicity of exhaust gases (mixture misfiring resulting in increased toxicity, catalytic converter malfunction, oxygen sensor malfunction, mismatch between oxygen sensor signals, and adsorber malfunction).
