Task

The "CHECK ENGINE" MIL notifies the driver of any exhaust-gas relevant faults.

Function

The "CHECK ENGINE" MIL is actuated at the ground end by the MESFI [ME] control unit (N3/10).

To check the bulb function it lights up for approx. 1 second when the ignition is switched "ON".

If there is no fault, the motor electronics control unit interrupts the actuation and the indicator lamp goes out.
