VUE FWD L4-2.4L (2008)
*
Use a scan tool to verify there are no brake pedal position sensor and/or transmission internal mode switch (IMS) DTCs set that could cause the
BCM not to provide battery voltage to the A/T shift lock solenoid.
*
If the automatic transmission shift lock control circuit is shorted to battery positive voltage, the A/T shift lock solenoid will be inoperative. The
vehicle will shift out of PARK without depressing the brake pedal, with Floor Shift. On vehicles with Column Shift the shifter will be locked in
PARK.

Circuit/System Verification
Ignition ON, clear the DTC. Observe the scan tool BCM Brake Applied Output Signal parameter while pressing and releasing the brake pedal. The
parameter should change between ON and OFF.
If the parameter does not change between the specified values, Refer to Stop Lamps Malfunction (See: Lighting and Horns/Testing and
Inspection/Symptom Related Diagnostic Procedures/Stop Lamps Malfunction) .
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the shift lock control solenoid.
2. Ignition OFF, test for less than 1.0 ohm between the ground circuit terminal A and ground.
‹› If greater than the specified range, test the ground circuit for an open/high resistance.
3. Install a test lamp between the ground circuit terminal A and the control circuit terminal B.
4. Ignition ON, command the scan tool BCM Brake To Shift Control output control ON and OFF. The test lamp should turn ON and OFF as
commanded.
‹› If the test lamp is always ON, test the control circuit for short to voltage. If the circuit tests normal, replace the BCM.
‹› If the test lamp is always OFF, test the control circuit for short to ground or an open/high resistance. If the circuit tests normal, replace the
BCM.
5. If the circuit tests normal, replace the transmission control.
Component Testing
1. Install a 10A fused jumper wire between the control circuit terminal 3 and 12 volts. Install a jumper wire between the ground circuit terminal 9 and
ground.
2. Listen for the solenoid to turn ON and OFF.
‹› If the function does not perform as specified, replace the transmission control.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Diagnostic Trouble
Code Tests and Associated Procedures/Verification Tests and Procedures) after completing the diagnostic procedure.
