Control Unit Input Test

Control Unit Input test

NOTE: Before testing, troubleshoot the multiplex integrated control system using B-CAN System Diagnosis Test Mode A.

1. Disconnect the 28P connector (A) from the HandsFreeLink control unit (B).






2. 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 3.

3. With the connector still disconnected, 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, the HandsFreeLink control unit must be faulty; replace it.
