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 (Body Control Module) processes the command and provides the appropriate output.

For vehicles with IA (Intelligent Access), when an RKE (Remote Keyless Entry) button is pressed on a IA (Intelligent Access) key, it sends a radio signal to the Remote Functions Receiver (RFR) module based on the user selected RKE (Remote Keyless Entry) transmitter button. The RFR (Remote Functions Receiver) module then communicates the RKE (Remote Keyless Entry) command to the Remote Function Actuator (RFA) module over a dedicated single circuit network. Once the RFA (Remote Function Actuator) module receives the RKE (Remote Keyless Entry) command, it sends the command to the BCM (Body Control Module) over the Medium Speed Controller Area Network (MS-CAN). The BCM (Body Control Module) receives the RKE (Remote Keyless Entry) 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 (Remote Keyless Entry) transmitter

PINPOINT TEST H : AN INDIVIDUAL BUTTON/FEATURE IS INOPERATIVE FROM THE RKE (Remote Keyless Entry) 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 (Body Control Module) PID TRUNK/LIFTGATE RELEASE OUTPUT (TRNK/LG_RLS)

- Enter the following diagnostic mode on the scan tool: BCM (Body Control Module) DataLogger.

- Select the BCM (Body Control Module) 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. INFORM the customer that any keys not present need to be programmed.
TEST the system for normal operation.

No
