Malfunction Indicator Lamp: Description and Operation
EPC Warning Lamp Operation
Electronic Power Control (EPC) Warning Lamp (Malfunction Indicator Lamp For Electronic Accelerator [E-Gas]) In Instrument Cluster,
Significance
The EPC warning lamp is the Malfunction Indicator Lamp for the electronic accelerator (E-gas) system.
Location of EPC warning lamp
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 electronic accelerator system (EGas) 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.
