Control Unit Input Test/Replacement

Control Unit Input Test/Replacement

1. Remove the driver's dashboard lower cover.
2. Remove the HFL control unit screws, then disconnect the 28P connector (A) from the HandsFreeLink control unit (B).






3. 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.
- If the terminals look OK, go to step 4.

4. 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 5.






5. 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 is faulty, replace it.
