Malfunction Indicator Lamp (MIL), function
WARNING: This page is about a different variant/trim than selected.
If emissions-influencing malfunctions are recognized by the TCM, the Malfunction Indicator Lamp (MIL) will be switched on.
Location of the MIL
NOTE:
When the MIL is switched on, it will either blink or light continuously. In either case, the DTC memory for the TCM must be checked, see ON BOARD DIAGNOSTIC (OBD II), CONDUCTING PROGRAM
.
- MIL flashing: there is a malfunction that could damage the Three Way Catalytic Converter (TWC). In this case, drive only with reduced power.
- MIL continuously on: there is a malfunction that degrades emissions. Check DTC memory for the Engine Control Module (ECM) and the TCM.
- If there are driveability problems (for example, a customer complaint) and the MIL is not on, the MIL functional test must be carried out, since malfunctions that do not immediately switch on the MIL can be stored.
