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 processes the command and provides the appropriate output. The RKE feature operates only when the ignition is off.

If the vehicle has been inactive for 28 days or longer, the RKE feature is switched off in the BCM to conserve battery power. The RKE feature is enabled again when the ignition is switched to RUN.

This pinpoint test is intended to diagnose the following:

- RKE transmitter battery
- RKE transmitter programming
- RKE transmitter
- BCM

PINPOINT TEST F: THE RKE TRANSMITTER IS INOPERATIVE - WITHOUT IA

NOTE: Aftermarket or dealer-installed systems may adversely affect the RKE system operation. Disconnect these systems before diagnosing any RKE concerns.

-------------------------------------------------
F1 CHECK FOR THE CORRECT RKE TRANSMITTERS

- NOTE: All RKE transmitters must be present to begin diagnosis of the RKE system.
- NOTE: Make sure the RKE 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 transmitters are used with the vehicle. Compare the RKE transmitters with the one shown in the Handles, Locks, Latches and Entry Systems Description and Operation information.
- Are all the correct RKE transmitters present?

Yes
GO to F2.

No
The system cannot be tested without all of the RKE transmitters. INFORM the customer that all of the correct RKE transmitters must be present to proceed with diagnosis of the system.

-------------------------------------------------
F2 CHECK THE OPERATION OF THE RKE TRANSMITTER WITH THE KEY IN THE OFF POSITION

- Ignition OFF.
- Check the operation of the RKE transmitter.
- Does the system operate correctly now?

Yes
The system is operating correctly. INFORM the customer of the correct vehicle behavior.

No
GO to F3.

-------------------------------------------------
F3 CHECK THE FUNCTIONALITY OF THE RKE 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 SYSTEM FOR NORMAL OPERATION WITH A SECOND TRANSMITTER

- Using the customer's second RKE 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 TRANSMITTER BATTERY

- Open the inoperative RKE 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 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 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 TRANSMITTER IS PROGRAMMED

- Program all of the RKE transmitters. Refer to Remote Keyless Entry (RKE) Transmitter Programming Transmitter.
- Check the inoperative RKE transmitter for correct operation.
- Does the inoperative RKE transmitter operate now?

Yes
The concern was caused by an unprogrammed RKE transmitter. INFORM the customer that any RKE transmitters not present need to be programmed.

No
REPLACE the inoperative RKE transmitter. PROGRAM all RKE transmitters. REFER to Remote Keyless Entry (RKE) Transmitter Programming Transmitter. INFORM the customer that any RKE transmitters not present need to be programmed. TEST the system for normal operation.

-------------------------------------------------
F7 PROGRAM ALL OF THE RKE TRANSMITTERS

- Program all of the RKE transmitters. Refer to Remote Keyless Entry (RKE) Transmitter Programming Transmitter.
- Check the RKE transmitters for correct operation.
- Do any of the RKE transmitters operate now?

Yes
The concern was caused by unprogrammed RKE transmitters. INFORM the customer that any RKE transmitters not present need to be programmed.

No
GO to F8.

-------------------------------------------------
F8 CHECK THE BCM FOR CORRECT OPERATION

- Disconnect all the BCM connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the BCM 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. REFER to Multifunction Electronic Modules Body Control Module (BCM). 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.
