- Remove the glove box (see GLOVE BOX REMOVAL/INSTALLATION ).
- Remove the passenger's dashboard undercover (see PASSENGER'S DASHBOARD UNDERCOVER REMOVAL/INSTALLATION ).
- Disconnect the 32P connector (A) from the HandsFreeLink control unit (B).
- Remove the mounting bolt (C) and loosen the bolt (D), then remove the bolts (E) and HandsFreeLink control unit from the bracket (F).
- Inspect the connector and socket terminals for a good pin fit 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 6.
- 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 7.
Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 1 BLK Under all conditions Measure the voltage to body ground:
There should be less than 0.2 V.- Poor ground(G503)
- An open in the wire
17 PNK Under all conditions Measure the voltage to body ground:
There should be battery voltage.- Blown No. 1 (15 A) fuse in the under-dash fuse/relay box
- An open in the wire
18 PUR Ignition switch in ACCESSORY or ON (II) Measure the voltage to body ground:
There should be battery voltage.- Blown No. 14 (7.5 A) fuse in the under-dash fuse/relay box
- An open in the wire
- Disconnect the 32P 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.
