Malfunction Indicator Lamp (MIL) -K83- In Instrument Cluster

Malfunction Indicator Lamp (MIL) -K83- In Instrument Cluster

If the ECM recognizes malfunctions that lead to a worsening of the emissions values, it indicates them by lighting the Malfunction Indicator Lamp (MIL) for exhaust.

The Engine Control Module (ECM) switches on the MIL after the ignition is switched on. Shortly after the engine is started, the exhaust MIL will go out. This requires, first of all, that the ECM does not detect a malfunction that worsens the emissions values and, secondly, that activation of the lamp by the ECM is OK.

If malfunctions that worsen the emissions are recognized during operation of the engine, the ECM switches on the exhaust MIL in the instrument cluster. (These malfunctions are listed in the DTC table). An entry is made in DTC memory at the same time.

The MIL can blink or remain lit continuously. The DTC memory should be checked in either case. DTC Memory, Checking

Continuously lit MIL
There is a malfunction that causes increased emissions. Check the DTC memory for the Motronic ECM and the automatic transmission (if equipped).

If a driveability problem exists and the Malfunction Indicator Lamp (MIL) does not light up, the DTC memory must be checked. There may be DTCs stored that do not cause the exhaust MIL to light up immediately, but only after engine is started again and the malfunction is recognized again.

Blinking MIL
There is a malfunction that causes damage to the catalytic converter in this driving condition (e.g. combustion misfire). In this case, the vehicle must only be driven at reduced power
