This PI was superseded to add second area for inspection, and add 2008 Model years. Please discard PIC4578.

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

### Condition/Concern:

A customer might complain that their power steering system is in "Default mode" and/or their Steering Wheel Radio Controls are inoperative. A condition has been identified through TAC cases that there is a common area for a wiring Short To Ground (STG) that could cause the EPS/STR Wheel control fuse to open.

### Recommendation/Instructions:

There are two locations for wiring concerns:

1. First check for a STG in circuit # 1539 (PNK) wire behind the radio. This circuit has reportedly been shorted on the radio mounting bracket, and just below the radio bracket almost to the BCM mounting location.

Note: For ease of locating this STG remove the radio, HVAC control head, and the upper console trim panels and inspect for wiring/brace contact.

2. Second check for a STG in circuit # 339 (PNK) wire behind the drivers side air bag.

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.
