Resistance Check
1) Disconnect ECM couplers (1) from ECM with ignition switch OFF.
CAUTION
!
Never touch terminals of ECM itself or connect voltmeter or ohmmeter (2).
2) Check resistance between each pair of terminals of disconnected couplers as listed in the following table.
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 the following table represents that when parts temperature is 20
°
C (68
°
F).
