Resistance Check
1) Remove ECM from its bracket referring to "Engine Control Module (ECM) Removal and Installation in Section 1C".
CAUTION
!
Never touch terminals of ECM itself or connect voltmeter or ohmmeter (2).
2) Connect special tool to ECM connectors (1) securely.
NOTE
Do not connect the other connector of special tool to ECM.
Special tool
(A): 09933–06320
3) Check resistance between each pair of terminals of special tool connectors (1) 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).
