2 Correction Important: This bulletin does not apply to vehicles built after the following dates: / : 5/1/07 Impala / Monte Carle: 3/1/07 For vehicles built after these dates, refer to SI for diagnosis and repair information. DO NOT REPLACE THE BCM. Important: The 2006 and 2007 Impala LS without AP8 does not have a coax antenna. The 2006 and 2007 without AP3 or AP8 does not have a coax antenna. 1. Replace the RCDLR module and the RCDLR antenna using the following procedure: 1.1. Remove the driver's side "A" pillar molding and I/P closeout panel Unplug the speaker To expose the RCDLR antenna, partially remove the driver's side upper I/P closeout panel (near windshield) Remove the clips holding the RCDLR antenna wire at the RCDLR module and 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 I/P carrier bolt and remove the old RCDLR antenna Remove the RCDLR module Install the new RCDLR module 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 Reinstall the I/P close-out panel Reconnect the speaker wire. Important: 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 I/P side closeout panel Remove the rear seat cushion Remove the rear seat back.

3 1.3. Lower and remove the trunk trim cover to gain access to the underside of the rear package shelf Remove the rear seat belts Remove the interior C-pillar trim (sail) panels and package shelf Remove the RCDLR module and antenna. Tip The existing antenna is grounded into another wiring harness. It will be necessary to pull the existing harness and antenna up near the C-pillar in order to disconnect the antenna from the other wiring harness. Important: The new antenna will not be grounded into the other wiring harness Install a new RCDLR module and antenna Tape back the harness ground connection Reinstall the rear package shelf Reinstall the interior C-pillar trim (sail) panels Reinstall the rear seat belts Reinstall the trunk trim cover Reinstall the rear seat back Reinstall the rear seat cushion Remove left rear C-pillar trim (sail) panel Remove the RCDLR antenna and receiver/module (located under the shelf package -- accessed through the trunk). Tip The existing antenna is grounded into another wiring harness. It will be necessary to pull the existing harness and antenna up near the C-pillar in order to disconnect the antenna from the other wiring harness. Important: The new antenna will not be grounded into the other wiring harness Reinstall the new antenna and RCDLR receiver/module Reinstall the C-pillar trim (sail) panel. Important: When programming a new or existing RCDLR, the programming instructions in SI must be followed. 2. Reprogram the RCDLR with the latest software update available through TIS2WEB. Important: 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. If this step is not performed, the RCDLR will not retain the tire pressures after the TPM system is learned.

4 Tip: When selecting the Tire Type/Pressure, choose the appropriate selection on the Tech 2 based on psi, not kpa. The vehicle must be driven immediately. Monitor the tire pressures on the DIC and drive the vehicle until dashes no longer appear. After the learn procedure is complete, be sure to set the tire pressures according to the information on the tire placard. 3. If equipped with Tire Pressure Monitoring System, perform the Tire Pressure Sensor Relearn using the J following the procedure found in SI. 4. Replace both Remote Keyless Entry transmitters. 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. 5. Program the transmitters using the procedure listed in SI. Parts Information Important: Refer to the parts catalog using the VIN of the vehicle being serviced to identify the correct part numbers.
