Resistance Check
1) Disconnect ECM (PCM) couplers from ECM (PCM) with ignition
switch OFF.
2) Check resistance between each pair of terminals of discon-
nected couplers as listed in following table.
1. ECM (PCM) coupler disconnected
2. Ohmmeter
CAUTION:
Never touch terminals of ECM (PCM) itself or connect
voltmeter or ohmmeter.
CAUTION:
Be sure to connect ohmmeter probe from wire har-
ness 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).
