Cavity Wire Color Test Condition Test: Desired Result Possible Cause if Desired Result is not Obtained 16 BLK Ignition switch in ACC (I) or ON (II) Measure the voltage to body ground:
There should be less than 0.2 V.- Poor ground (G501)
- An open in the wire
31 PUR Ignition switch in ACC (I) or ON (II) Measure the voltage to body ground:
There should be battery voltage.- Blown No. C13 (7.5 A) fuse in the driver's under-dash fuse/relay box
- An open in the wire
32 ORN Under all conditions Measure the voltage to body ground:
There should be battery voltage.- Blown No. B15 (20 A) fuse in the under-hood fuse/relay box
- An open in the wire
- Disconnect the 32P connector again, and make this input test at the connector.
If the input test proves OK, the HandsFreeLink control unit is faulty, replace it.
