Condition
Customers may comment about one or more of the following conditions:
The remote keyless entry (RKE) transmitters will not program, function and/or the RKE transmitter low battery message is displayed.
The Service Tire Monitor System message is displayed.
The new RKE transmitters cannot be programmed.
Cause
Any of these concerns may be caused by an internal fault with the transmitters and/or the RCDLR software/hardware.
Correction
DO NOT REPLACE THE BCM OR RADIO ANTENNA MODULE.
When programming a new or existing RCDLR, the programming instructions in SI must be followed.
On vehicles equipped with Tire Pressure Monitoring (TPM), the tire type and tire pressures must be selected in the module set-up using the Tech 2(R). If this step is not performed, the RCDLR will not retain the tire pressures after the TPM system is learned.
Tip: When selecting the Tire Type/Pressure. choose the appropriate selection on the Tech 2 based on psi. not kPa.
Relearn the TPM sensors using the J 46079 and following the procedure found in SI.
Reprogram the RCDLR with the latest software update available through TIS2WEB.
New transmitters are identified by a star on the back of the transmitter. It is important to verify that the replacement transmitters have a star on the back.
Replace both Remote Keyless Entry transmitters.
Program the transmitters using the procedure listed in SI.
Perform the following steps in the exact order:
Remove the key from the ignition.
Open and close the driver's door.

If the customer's concerns are corrected, no further repairs are required.
