Inspection of ECM and Its Circuits

ECM and its circuits can be checked at ECM wiring connectors by
measuring voltage and resistance.
CAUTION:
ECM cannot be checked by itself. It is strictly prohibited
to connect voltmeter or ohmmeter to ECM with connector
disconnected from it.
VOLTAGE CHECK
1) Remove ECM from body referring to Section 6E.
2) Check voltage at each terminal of connectors connected.
NOTE:
As each terminal voltage is affected by the battery volt-
age, confirm that it is 11 V or more when ignition switch
is ON.
