Shift Lock Control Solenoid B+ | B2710 02 | B2710 02 | -- | -- |
Shift Lock Control Solenoid Control | B2710 02 | B2710 02 | B2710 01 | -- |
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.
• | The ignition switch is in the ON position. |
• | The brake pedal is pressed. |
• | The transmission gear selector is in the PARK position. |
• | DTC B2710 01 sets when the solenoid control circuit is shorted to voltage. |
• | DTC B2710 02 sets when the solenoid control or supply circuit is open or shorted to ground, |
The RCDLR will not attempt to ground the control circuit of the automatic transmission shift lock solenoid until the next key cycle.
• | A current DTC will clear when the malfunction is no longer present and the ignition switch is cycled. |
• | All RCDLR history codes will clear after 100 ignition cycles with no current codes active during the 100 ignition cycles. |

⇒ | If the parameter does 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.
