Condition
Some 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.
Complete the following repair procedures for all vehicles listed in this bulletin:
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.
Close all other doors/trunk/liftgates.
Wait 5 minutes.
Press the Unlock Button and verify that the doors all unlock.
IMPALA ONLY - proceed to step 5.
If the customer's concerns are corrected, no further repairs are required.
If the customer's concerns are NOT corrected, proceed with step 6.
IMPALA ONLY - the RCDLR antenna MUST be replaced. Use the following procedure to complete the RCDLR antenna replacement. The 2006 and 2007 Impala LS without AP8 does not have a coax antenna.
Remove the driver's side A-pillar molding and I/P closeout panel.
Unplug the speaker.
To expose the remote control door lock receiver (RCDLR) antenna, partially remove the driver's side upper IP closeout panel (near windshield).
Remove the clips holding the RCDLR antenna wire at the RCDLR antenna module and disconnect the RCDLR antenna from module.
Remove the remaining clips along the A-pillar.
Cut the old RCDLR antenna wire a minimum of 152 mm (6 in) from the button (connecting to the windshield), leaving that portion of the old RCDLR antenna connected to the windshield.
Remove the IP carrier bolt and remove the old RCDLR antenna.
Lay in the new RCDLR antenna and reinstall the carrier bolt.
Connect the new antenna to the RCDLR antenna module.
Clip the new RCDLR antenna into place using the existing holes on the A-pillar. Verify the customer's concern is corrected.
If the customer's concern is not corrected, proceed with step 6.
If it is corrected, complete steps 5.12 thru 5.14. No further repairs are required. Reinstall the I/P close-out panel.
Reconnect the speaker wire.
Be sure that the end of the old RCDLR antenna is tucked behind the A-pillar molding. The button on the windshield is no longer functional, however leaving the cover on the button will provide a cleaner look to the vehicle.
Reinstall the A-pillar molding and IP side closeout panel.
In most cases, steps 1-3 will correct the customer's concern. In a few cases, it may be necessary to replace the RCDLR.
If the customer's concern is still present, replace the RCDLR.
Program the RCDLR with the latest software update available through TIS2WEB.
Reprogram both Remote Keyless Entry transmitters.
