Alarm Module: Testing and Inspection

Immobilizer Control Unit-Receiver Input Test

NOTE: Before troubleshooting check the No. 7 (7.5 A) and No. 19 (15 A) fuses in the under-dash fuse/relay box.

1. Remove the driver's dashboard lower cover. Drivers Dashboard Lower Cover Removal/Installation

2. Remove the steering column covers. Steering Column Removal and Installation

3. Disconnect the 7P connector (A) from the immobilizer control unit-receiver (B).

4. Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.

- If the terminals look OK, go to step 5.

5. Reconnect the connector to the immobilizer control unit-receiver, and do these input tests at the following connector.
- If any test indicates a problem, find and correct the cause, then recheck the system.

- If all the input tests prove OK, the immobilizer control unit-receiver must be faulty; replace it.
