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

Normal Operation

The Remote Keyless Entry (RKE) transmitter in the Intelligent Access (IA) key 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 command to the Remote Function Actuator (RFA) module, and the RFA (Remote Function Actuator) module carries out the selected action.

Upon a request to lock/unlock the doors the RFA (Remote Function Actuator) module controls the door lock actuators. Upon a request to open/close the power liftgate, the RFA (Remote Function Actuator) module sends a voltage signal to the Liftgate/Trunk Module (LTM). Upon a panic alarm request, the RFA (Remote Function Actuator) module sends a message to the Smart Junction Box (SJB) over the Medium Speed Controller Area Network (MS-CAN) to activate the turn signals and horn.

This pinpoint test is intended to diagnose the following:

- Door locks

- Horn system

- Power liftgate system

- Turn signal system

- IA (Intelligent Access) key

PINPOINT TEST K : AN INDIVIDUAL BUTTON/FEATURE IS INOPERATIVE FROM THE RKE (Remote Keyless Entry) TRANSMITTER

NOTE: The panic feature only operates when the ignition is in the OFF mode.

K1 VERIFY THE DOOR LOCK OPERATION

- Press the lock and unlock button on the driver door lock control switch while observing the door lock operation.

Do the door locks operate correctly?

Yes
GO to K2.

Do the hazard lamps operate correctly?

Yes
GO to K3.

No
REFER to Lighting and Horns.

K3 VERIFY THE HORN OPERATION

- Enter the following diagnostic mode on the scan tool: SJB (Smart Junction Box) DataLogger.

- Select the SJB (Smart Junction Box) PID (HORN) and active command the horn on.

Does the horn sound when commanded on?

Yes
GO to K4.

No
REFER to Horn.

K4 VERIFY THE LIFTGATE OPERATION

- Enter the following diagnostic mode on the scan tool: RFA (Remote Function Actuator) DataLogger.

- Select the RFA (Remote Function Actuator) module PID (Trunk_Unlk_R) and active command the liftgate to open.

Does the power liftgate open?

Yes
REPLACE and PROGRAM the inoperative IA (Intelligent Access) key. TEST the system for normal operation.

No
