Pinpoint Test F: The Remote Keyless Entry (RKE) Transmitter Is Inoperative - Without Intelligent Access (IA)
Handles, Locks, Latches and Entry Systems
Pinpoint Test F: The Remote Keyless Entry (RKE) Transmitter Is Inoperative - Without Intelligent Access (IA)
Normal Operation
Remote locking and unlocking of the doors and releasing the luggage compartment lid/liftgate 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. The RKE (Remote Keyless Entry) feature operates only when the ignition is off.
If the vehicle has been inactive for 28 days or longer, the RKE (Remote Keyless Entry) feature is switched off in the BCM (Body Control Module) to conserve battery power. The RKE (Remote Keyless Entry) feature is enabled again when the ignition is switched to RUN.
This pinpoint test is intended to diagnose the following:
- RKE (Remote Keyless Entry) transmitter battery
- RKE (Remote Keyless Entry) transmitter programming
- RKE (Remote Keyless Entry) transmitter
- BCM (Body Control Module)
PINPOINT TEST F : THE RKE (Remote Keyless Entry) TRANSMITTER IS INOPERATIVE - WITHOUT IA (Intelligent Access)
NOTE: Aftermarket or dealer-installed systems may adversely affect the RKE (Remote Keyless Entry) system operation. Disconnect these systems before diagnosing any RKE (Remote Keyless Entry) concerns.
F1 CHECK FOR THE CORRECT RKE (Remote Keyless Entry) TRANSMITTERS
- NOTE: All RKE (Remote Keyless Entry) transmitters must be present to begin diagnosis of the RKE (Remote Keyless Entry) system.
NOTE: Make sure the RKE (Remote Keyless Entry) transmitters are those provided with the OEM system and not from an aftermarket system, or a dealer-installed system that may have been installed on the vehicle.
Verify the correct RKE (Remote Keyless Entry) transmitters are used with the vehicle. Compare the RKE (Remote Keyless Entry) transmitters with the one shown in the Handles, Locks, Latches and Entry Systems Description and Operation portion.
Are all the correct RKE (Remote Keyless Entry) transmitters present?
Yes
GO to F2.
No
The system cannot be tested without all of the RKE (Remote Keyless Entry) transmitters. INFORM the customer that all of the correct RKE (Remote Keyless Entry) transmitters must be present to proceed with diagnosis of the system.
F2 CHECK THE OPERATION OF THE RKE (Remote Keyless Entry) TRANSMITTER WITH THE KEY IN THE OFF POSITION
- Ignition OFF.
- Check the operation of the RKE (Remote Keyless Entry) transmitter.
Does the system operate correctly now?
Yes
The RKE (Remote Keyless Entry) feature may have been switched off in the BCM (Body Control Module) to conserve battery power. The RKE (Remote Keyless Entry) feature enables again when the ignition is switched to RUN. TEST the system for normal operation. INFORM the customer of the correct vehicle behavior.
No
GO to F3.
F3 CHECK THE FUNCTIONALITY OF THE RKE (Remote Keyless Entry) TRANSMITTER
- Press each button on the transmitter.
Does any button operate correctly?
Yes
GO to Pinpoint Test H Pinpoint Test H: An Individual Button/Feature Is Inoperative From The Remote Keyless Entry (RKE) Transmitter.
No
GO to F4.
F4 CHECK THE RKE (Remote Keyless Entry) SYSTEM FOR NORMAL OPERATION WITH A SECOND TRANSMITTER
- Using the customer's second RKE (Remote Keyless Entry) transmitter that is correct for the vehicle, attempt to lock and unlock the doors.
Do the doors lock and unlock with the second transmitter?
Yes
GO to F5.
No
GO to F7.
F5 CHECK THE INOPERATIVE RKE (Remote Keyless Entry) TRANSMITTER BATTERY
- Open the inoperative RKE (Remote Keyless Entry) transmitter.
- Do not clean off any grease from the battery terminals on the back surface of the circuit board.
- Verify the correct battery is used (CR2032).
- Remove the RKE (Remote Keyless Entry) transmitter battery and measure the voltage.
Is the voltage greater than 2.5 volts?
Yes
GO to F6.
No
INSTALL a new battery. DO NOT reprogram the RKE (Remote Keyless Entry) transmitters (weak or dead batteries do not erase Transmitter Identification Codes (TICs) from memory). TEST the system for normal operation.
F6 CHECK IF THE RKE (Remote Keyless Entry) TRANSMITTER IS PROGRAMMED
- Program all of the RKE (Remote Keyless Entry) transmitters. Refer to Remote Keyless Entry (RKE) Transmitter Programming RKE (Remote Keyless Entry) Transmitter.
- Check the inoperative RKE (Remote Keyless Entry) transmitter for correct operation.
Does the inoperative RKE (Remote Keyless Entry) transmitter operate now?
Yes
The concern was caused by an unprogrammed RKE (Remote Keyless Entry) transmitter. INFORM the customer that any RKE (Remote Keyless Entry) transmitters not present need to be programmed.
No
REPLACE the inoperative RKE (Remote Keyless Entry) transmitter. PROGRAM all RKE (Remote Keyless Entry) transmitters. REFER to Remote Keyless Entry (RKE) Transmitter Programming RKE (Remote Keyless Entry) Transmitter. INFORM the customer that any RKE (Remote Keyless Entry) transmitters not present need to be programmed. TEST the system for normal operation.
F7 PROGRAM ALL OF THE RKE (Remote Keyless Entry) TRANSMITTERS
- Program all of the RKE (Remote Keyless Entry) transmitters. Refer to Remote Keyless Entry (RKE) Transmitter Programming RKE (Remote Keyless Entry) Transmitter.
- Check the RKE (Remote Keyless Entry) transmitters for correct operation.
Do any of the RKE (Remote Keyless Entry) transmitters operate now?
Yes
The concern was caused by unprogrammed RKE (Remote Keyless Entry) transmitters. INFORM the customer that any RKE (Remote Keyless Entry) transmitters not present need to be programmed.
No
GO to F8.
F8 CHECK THE BCM (Body Control Module) FOR CORRECT OPERATION
- Disconnect all the BCM (Body Control Module) connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the BCM (Body Control Module) connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
Is the concern still present?
Yes
INSTALL a new BCM (Body Control Module). TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
