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

Condition/Concern
Depending on vehicle options some owners may have any of the following concerns:
– RKE Inoperative
– Passive Entry and Start Inoperative
– No Fob Detect Message on DIC
– Service Tire Pressure System
– No Audio
– Touch Screen Inoperative

These concerns could be caused by the dash harness (2) being pinched between the left I/P dash mounting bracket
(1) and the body, as shown below. In many cases, the complete harness is not pinched and may not be as apparent
as shown in the below photo. When inspecting for a pinched harness, make sure the harness can be moved freely
away from the bracket to body interface.

Recommendation/Instructions
To repair this concern, loosen the left I/P dash mounting bracket bolts and pull the harness free. Open the harness
and repair any damaged wires as necessary.
