The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Shifter Stuck in Park
Before replacing any components, verify correct operation of the Stop Lamp Switch. Check for proper adjustment of the switch, poor electrical connection at the switch or incorrect operation of the switch contacts and repair as necessary. It has been identified that the brake switch is more likely the cause compared to the shifter assembly.
Do NOT replace the shifter unless the brake switch has been replaced or adjusted and the condition returns again.
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.
