This PI was superseded to update model years. Please discard PIT4035.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Multiple electrical concerns and the vehicle may not crank or start. This may be the result of an open ING E fuse. There have been 3 areas of concerns were the ignition E fuse circuit 639 (Pink Wire) or Circuit 420 (Purple Wire) may chafe and cause the fuse to open.
If the ignition E fuse is open, inspect the following 3 areas. Be sure to inspect these wires closely. Typical contact will be a small pin hole into the insulation of the wire.
Note: If any of the 3 situations located above are identified, it is recommended that the wire(s) are repaired and the harness is re-routed or protected to prevent future concerns.
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.
