Immobilizer control module can be checked at wiring connectors by measuring voltage.
CAUTION:
Immobilizer control module can not be checked by itself. It is strictly prohibited to connect voltmeter
or ohmmeter to immobilizer control module with coupler disconnected from it.

As the battery voltage affects each terminal voltage, confirm that it is 11 V or more when ignition switch
is turned to ON position.
