Resistance Check

1. Remove ECM from its bracket.

CAUTION:
Never touch terminals of ECM itself or connect voltmeter or ohmmeter (2).

2. Connect special tool (A) to ECM connectors (1) securely.

NOTE:
Do not connect the other connector of special tool to ECM.




3. Check resistance between each pair of terminals of special tool connectors as listed in the table.

CAUTION:
- Be sure to connect ohmmeter probe from wire harness side of coupler.
- Be sure to turn OFF ignition switch for this check.
- Resistance in the table represents that measured when parts temperature is 20 degrees C (68 degrees F).
