10C-12 Immobilizer Control System:
Inspection of Immobilizer Control Module and Its Circuit
Immobilizer control module and its circuit can be checked at immobilizer control module wiring connector by
measuring voltage.
CAUTION:
Immobilizer control module cannot be checked by itself. It is strictly prohibited to connect voltmeter or
ohmmeter to immobilizer control module with connector disconnected from it.
Voltage Check
1) Remove immobilizer control module (1) from steering lock assembly referring to "Immobilizer Control Module
Removal and Installation: ".
2) Connect immobilizer control module wiring connector (2) to immobilizer control module.
3) Check voltage at each terminal.
