Pinpoint Test H: An Individual Button/Feature Is Inoperative From The Remote Keyless Entry (RKE) Transmitter

Normal Operation

For vehicles without Intelligent Access (IA) the remote locking and unlocking of the doors and releasing the luggage compartment lid/liftgate latch is accomplished by the Body Control Module (BCM) receiving a command message from the Remote Keyless Entry (RKE) transmitter. The BCM processes the command and provides the appropriate output.

For vehicles with IA, when an RKE button is pressed on a IA key, it sends a radio signal to the Remote Functions Receiver (RFR) module based on the user selected RKE transmitter button. The RFR module then communicates the RKE command to the Remote Function Actuator (RFA) module over a dedicated single circuit network. Once the RFA module receives the RKE command, it sends the command to the BCM over the Medium Speed Controller Area Network (MS-CAN). The BCM receives the RKE command and either locks or unlocks the doors or releases the luggage compartment lid/liftgate.

This pinpoint test is intended to diagnose the following:

- Door locks
- Luggage compartment lid/liftgate release
- RKE transmitter

PINPOINT TEST H: AN INDIVIDUAL BUTTON/FEATURE IS INOPERATIVE FROM THE RKE TRANSMITTER

-------------------------------------------------
H1 VERIFY THE DOOR LOCK OPERATION

- Press the door lock control switch twice while observing the door lock operation.
- Do the door locks operate correctly?

Yes
GO to H2.

No
IDENTIFY the correct symptom and GO to Symptom Chart - Electrical. Symptom Related Diagnostic Procedures

-------------------------------------------------
H2 VERIFY THE LUGGAGE COMPARTMENT LID/LIFTGATE LATCH OPERATION USING THE BCM PID TRUNK/LIFTGATE RELEASE OUTPUT (TRNK/LG_RLS)

- Enter the following diagnostic mode on the scan tool: BCM DataLogger.
- Select the BCM PID TRNK/LG_RLS and active command the luggage compartment lid/liftgate to release.
- Does the luggage compartment lid/liftgate release?

Yes
REPLACE and REPROGRAM the inoperative key. REFER to Anti-Theft - Passive Anti-Theft System (PATS) Key Programming for the key programming procedures. INFORM the customer that any keys not present need to be programmed. TEST the system for normal operation.

No
GO to Pinpoint Test E. Pinpoint Test E: The Luggage Compartment Lid/Liftgate Latch Release Is Inoperative/Does Not Operate Correctly
