Resistance At ECM Connectors:





The ECM and it's circuits can be checked at the ECM terminals by measuring voltage and resistance.

CAUTION: The ECM cannot be checked by itself. Never connect a DVOM to the ECM pins without the harness connected.


RESISTANCE CHECKS

- Disconnect harness from ECM.
