1. Remove the center console (see page 20-92).
2. Remove the console lower box (see page 20-95).
3. Disconnect the 28P connector (A) from the HandsFreeLink control unit (B).
4. Inspect the connector and socket terminals for a good pinfit 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.

5. Reconnect the connector and make these input tests at the 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. Disconnect the 28P connector again, and make this input test at the connector. If the test indicates a problem, find and correct the cause, then recheck the system.
If the input test proves OK, the HandsFreeLink control unit must be faulty, replace it.
