Circuit Operation
The engine or powertrain control module (ECM or
PCM) receives inputs from the engine sensors and
switches, controlling the functions of the engine. It also
turns on the malfunction indicator “check engine” light
whenever a malfunction or abnormal engine perfor-
mance is detected, and allows for diagnostic testing
through the data link connector (DLC).
Refer to Section 6 of the Workshop Manual for further
engine diagnosis.
