Electronic Throttle Warning Lamp In Instrument Cluster

NOTE: Electronic power control (EPC) warning lamp -K132- is also known as the EPC warning lamp (EPC = electronic power control).

"EPC" stands for Electronic Power Control and refers to the electronic throttle control system.







Installation location of EPC warning lamp

When the ignition is switched on the engine control module tests all the components whose functions relate to the electronic throttle system.

The engine control module activates the EPC warning lamp when the ignition is switched on. The warning lamp will go out soon after the engine starts, provided that the engine control module does not detect any faults in the electronic throttle system and the activation of the lamp via the engine control module is working properly.

If a fault is detected in the electronic throttle system while the engine is running, the engine control module will activate the EPC warning lamp (see Fault Table for list of possible faults). At the same time a Diagnostic Trouble Code (DTC) is stored in the Diagnostic Trouble Code (DTC) memory of the engine control module.
