CHECK ENGINE Lamp

CHECK ENGINE Lamp



The lamp is located in the main instrument unit and is powered from +15. The lamp is controlled from control module pin 32 and goes on when the ignition is turned on.

As soon as the control module receives impulses from the crankshaft position sensor, the lamp will go out unless OBD II diagnostics activates it.

Diagnosis


There is no diagnosis for the electric circuit to the lamp.

However, the lamp should give a constant light when the ignition is turned on. Bear in mind that TCM may request the lamp go on.
