The engine control module checks all the important functions of the electronic accelerator system after switching the ignition on.

The instrument cluster switches the EPC warning lamp on for about 1 second during the test of this component. If a malfunction is recognized during the test, the lamp will light continuously.

If malfunctions are recognized in the engine Electronic Power Control (EPC) system when the engine is in operation, the engine control module will send a message to the instrument cluster, and the instrument cluster will switch on the EPC warning lamp (these malfunctions are indicated in the DTC table). Simultaneously, an entry is made in the engine control module DTC memory.
