RESISTANCE CHECK
1) Disconnect ECM (PCM) 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 terminal of couplers discon-
nected.
CAUTION:
D Be sure to connect ohmmeter probe from wire har-
ness side of coupler.
D Be sure to turn OFF ignition switch for this check.
D Resistance in table below represents that when
parts temperature is 20_C (68_F).
