Deck Lid Release Switch Failure

Monitored & Set Condition

1. When Monitored: Continuously.
2. Set Condition: The BCM monitors voltage present on the deck lid release switch output circuit. If voltage is present for over 30 seconds, this DTC will set.

Possible Causes:

• Checking DTC Priority
• Defective Deck Lid Release Switch
• Deck Lid Release Switch Output Circuit Shorted To Voltage
• Body Control Module

Testing

1. Turn ignition off. Connect scan tool to Data Link Connector (DLC). Turn ignition on. Wait 30 seconds. Using scan tool, clear Body Control Module (BCM) Diagnostic Trouble Codes (DTC). Press deck lid release switch several times. Using scan tool, retrieve BCM DTCs. If DECK LID RELEASE SWITCH FAILURE DTC resets, go to next step. If DECK LID RELEASE SWITCH FAILURE DTC does not reset, fault may be intermittent. Check related wiring and connectors for poor connections or damage to wiring harness. See WIRING DIAGRAMS  . Repair any problems found as necessary. If no problems are found, check if any Technical Service Bulletins (TSBs) apply to vehicle. If no TSBs apply, test is complete.
2. Turn ignition off. Disconnect 2-pin deck lid release switch connector. Turn ignition on. Using scan tool, clear DTCs. Cycle ignition switch off, then on. Wait 30 seconds. Using scan tool, retrieve DTCs. If DECK LID RELEASE SWITCH FAILURE DTC resets, leave deck lid release switch connector disconnected and go to next step. If DECK LID RELEASE SWITCH FAILURE DTC does not reset, replace deck lid release switch. See POWER DOOR LOCKS & TRUNK RELEASE - CONCORDE, INTREPID & 300M article.
3. Turn ignition off. Disconnect Body Control Module (BCM) connector C1. Turn ignition on. Measure voltage on deck lid release switch connector terminal No. 1, deck lid release switch output circuit (Black/White wire). If any voltage exists, repair short to voltage in Black/White wire. If no voltage exists, replace BCM. See BODY CONTROL MODULE  under REMOVAL & INSTALLATION.
