The remote control door lock receiver (RCDLR) controls the automatic transmission shift lock solenoid by providing a ground for the solenoid. The RCDLR utilizes a smart driver to control the ground to the automatic transmission shift lock solenoid. The smart driver monitors the voltage and current flow of the control circuit.

⇒ | If the parameter did not change, refer to Stop Lamps Malfunction. |
⇒ | If the test lamp does not illuminate , test the B+ circuit for a short to ground or open/high resistance. If the circuit tests normal, test or replace the shift lock control solenoid. |
⇒ | 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 or short to voltage. If the circuit test normal, replace the RCDLR. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
