Circuit/System Verification
1. Ignition ON, Clear the DTC. Observe the scan tool RCDLR Shift Lock Solenoid Command parameter. The parameter should change from
UNLOCK to LOCK when the brake pedal is depressed and released.
‹› If the parameter did not change, refer to Stop Lamps Malfunction (See: Lighting and Horns/Testing and Inspection/Symptom Related
Diagnostic Procedures/Stop Lamps Malfunction) .
2. Ignition ON, observe the scan tool RCDLR Shift Lock Solenoid State parameter. The parameter should change from UNLOCK to LOCK OFF
when the brake pedal is depressed and released.
‹› If the parameter does not change, replace the RCDLR.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the shift lock control solenoid.
2. Ignition ON, test between the Ignition voltage circuit terminal E and ground.
‹› If the test lamp did not illuminate , test the Ignition voltage circuit for a short to ground or an open/high resistance.
3. Install a test lamp between circuit terminal E and the control circuit terminal K.
4. Ignition ON, depress and release the brake pedal several times. The test lamp should turn ON and OFF as commanded.
‹› If the test lamp is always ON, test the control circuit for short to ground. If the circuit tests normal, replace the RCDLR.
‹› If the test lamp is always OFF, test the control circuit for an open/high resistance.If the circuit test normal, replace the RCDLR.
5. If the circuit tests normal, replace the shift lock control solenoid.
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.
