ENGINE GENERAL INFORMATION AND DIAGNOSIS (J18 ENGINE WITH WU TWC) 6-2-35
RESISTANCE CHECK
1) Disconnect ECM couplers from ECM with ignition switch OFF.
CAUTION:
Never touch terminals of ECM itself or connect volt-
meter 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 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).
