Resistance Check
1) Disconnect ECM couplers from ECM with ignition switch
OFF.
CAUTION:
Never touch terminals of ECM itself or connect voltmeter
or ohmmeter.
2) Check resistance between each terminal of connectors dis-
connected.
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 table below represents that when parts
temperature is 20°C (68°F).
1. ECM coupler disconnected
2. Ohmmeter
