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

Condition/Concern:

Owners may comment on a no crank concern and the Ign A fuse in the UBEC is blown. If the Ign A fuse is blown, inspect for circuit 142 (yellow or red) for being pinched between the steering column IP support bracket and the metal knee bolster deflector. See Doc ID # 1454278 step 9 for a picture of the metal knee bolster deflector.

Recommendation/Instructions:

Repair the shorted circuit as necessary and reroute harness so the knee bolster deflector does not pinch the harness during reassembly.

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.
