Engine Control Module: Description and Operation
SELF-DIAGNOSIS
The Engine Control Module (ECM) monitors the input/output signals (some signals at all times and the others under specified conditions). When
the ECM detects that an irregularity, it memorizes the diagnostic trouble code, and outputs the signal to the self-diagnosis output terminal. The
diagnosis results can be read out Scan Tool. Diagnostic Trouble Code (DTC) will remain in the ECM as long as battery power is maintained. The
diagnostic trouble code will, however, be erased when the battery terminal or the ECM connector is disconnected or erased by Generic Scan Tool.
