The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

It may be noticed after the center console wiring harness has been replaced that there is no sound from the rear speakers. While installing the harness, there will be one extra connector not used, which would be for the RSA (Rear Seat Audio).

Recommendation/Instructions:

The center console wiring harness is the same for vehicles equipped with or without RSA (RPO UK6). When a center console wiring harness is replaced on a vehicle NOT equipped with RSA, 5 pairs of wires for the RSA connector must be spliced together. Use the following chart to help in splicing the pairs:

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
