EPC Warning Lamp Operation



Malfunction Lamp For Electronic Throttle In Instrument Cluster

NOTE: The Electronic Power Control (EPC) Warning Lamp -K132- is also known as the EPC warning lamp.

"EPC" is an abbreviation for Electronic Power Control and refers to the electronic throttle control system.

When the ignition is switched on, the engine control module checks all the components of importance to the electronic throttle system.
After switching on the ignition the engine control module switches on the EPC warning lamp. The EPC warning lamp goes out shortly after starting the engine, if on the one hand, the engine control module does not detect any malfunctions in the EPC system, and, if actuation of the lamp by the engine control module is OK.

If a malfunction is detected in the electronic throttle system while the engine is running, the engine control module switches on the EPC warning lamp. (These DTCs are listed in the DTC table). At the same time, an entry is made in the engine control module Diagnostic Trouble Code (DTC) memory.
