The exterior trunk release switch is located just under the lip of the deck lid in the license plate pocket area. With the exterior trunk release switch turned on, the RCDLR receives the grounding signal.

The headliner and console antennas share a driver within the remote control door lock receiver (RCDLR) and are wired in parallel. The RCDLR has no way to determine which antenna is receiving a valid response from a transmitter, only that a valid response is being received.

This diagnostic procedure supports the following DTC:

This vehicle has DTCs which include DTC Symptoms. Refer to DTC Symptom Description for more DTC information.

The exterior trunk release switch is a momentary switch, and the RCDLR will set DTC B3618 when the switch circuit is ON for more than 3 minutes.

Once the inputs were deemed as shorted, the RCDLR will clear the current DTC, and consider the later persisted state as valid.

An intermittently stuck switch can cause this DTC to set. Refer to Testing for Intermittent Conditions and Poor Connections.
