Attention: Proceed with this bulletin ONLY if the customer has commented about this concern AND the EI number is listed in GMVIS. If the customer has not commented about this condition or the EI does not show in GMVIS, disregard the bulletin and proceed with diagnostics found in published Service Information. THIS IS NOT A RECALL -- refer to Corporate Bulletin Number 04-00-89-053 for more details on the use of Engineering Information Bulletins.

Condition

Some customers may comment on not being able to shift out of park. In some cases, this may be associated with a comment that the brake lights are inoperative.

Cause

GM Engineering is attempting to determine the cause of the above condition. GM Engineering has a need to obtain information firsthand during diagnosis and after repair. As a result, this information will be used by engineering to "root cause" the customer's concern and develop/validate a field fix.

Follow the strategy based diagnostics below and fax a copy of the repair order to Al Ferry at 586-492-1500. All diagnostic information must be written on the repair order.

  1. Verify that the VIN and mileage are correct on the repair order.
  2. Press and hold the brake pedal. Do the stop lamps illuminate?
    3. • Yes - Go to Step 4.
    • No - Go to Step 3.
  3. Is there power at the stoplamp switch?
    4. • Yes - Go to Step 6.
    • No - Inspect and replace the backup lamp fuse and check for a short to ground in the stop lamp circuit. (Refer to SI for Stoplamp Switch Schematic.)
  4. Check for ground at the park position switch with the connector connected (back probe). Is there ground?
    5. • Yes - Go to Step 5.
    • No - Replace the park position switch. (Refer to SI for Shift Lock Control Schematic.)
  5. Is there power at the shift lock control solenoid?
    6. • Yes - Replace the shift lock control solenoid.
    • No - Check for an open between the shift lock control solenoid and the smart junction block (fuse block). If no trouble is found, replace the smart junction block (fuse block).
  6. Press the brake pedal. Watch the stoplamp switch shaft. Does the stoplamp switch shaft stick?
    7. • Yes -- Replace the stoplamp switch.
    • No -- Go to Step 7

  7. Is there a gap between the brake pedal bracket and the stoplamp switch when not pressing the pedal? Refer to the graphic above which illustrates where to find the gap.
    8. • Yes - Adjust the stoplamp switch. Refer to for more information on Stoplamp Switch Adjustment.
    • No - Perform Stoplamp Switch Diagnosis per SI.

Important: All diagnostic information must be written on the repair order. Fax a copy of the repair order to Al Ferry at 586-492-1500.
