A/C SYSTEM INSPECTION OF ECM AND ITS
CIRCUITS
ECM and its Circuits can be checked at ECM wiring couplers by
measuring voltage.
Voltage Check
1) Remove ECM (1) from vehicle.
2) Connect ECM (1) couplers to ECM.
3) Check voltage at each terminal of couplers connected.
Refer to “Inspection of ECM and its circuit” in ENGINE AND
EMISSION CONTROL SYSTEM section.
NOTE:
As each terminal voltage is affected by the battery voltage,
confirm that it is 11V or more when ignition switch is ON.
CAUTION:
ECM cannot be checked by itself. It is strictly prohibited
to connect voltmeter or ohmmeter to ECM with couplers
disconnected from it.
