Honda Accord: Immobilizer-Keyless Control Unit Input Test

NOTE: Before testing, troubleshoot the multiplex integrated control unit first, using B-CAN System Diagnosis Test Mode A (see page 22-134).

1. Remove the driver's dashboard lower cover (see page 20-166).

2. Remove the steering column covers (see page 20-181).

3. Disconnect the 7P connector (A) from the immobilizer-keyless control unit (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. With the connector still disconnected, 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, go to step 6.

6. Reconnect the connector to the immobilizer-keyless control unit, 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, replace the immobilizer-keyless control unit (see page 22-440).

NOTE: If you replace the immobilizer-keyless control unit, do the immobilizer registration (see page 22-439).
