Resistance Check

1. Remove ECM from its bracket referring to Engine Control Module (ECM) Removal and Installation.

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 following 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 following table represents that measured when parts temperature is 20 °C (68 °F).
