Resistance Check
1) Disconnect couplers from ECM/PCM with ignition switch OFF.
CAUTION:
Never touch terminals of ECM/PCM itself or connect
voltmeter or ohmmeter.
2) Check resistance between each pair of terminals of discon-
nected couplers as listed in the following table.
CAUTION:
D Be sure to connect ohmmeter probe from wire harness
D Be sure to turn OFF ignition switch for this check.
D Resistance in table represents that when parts temper-
