This bulletin is being revised to include an "Important" statement containing breakpoint information based on the vehicle's build date. Please discard Corporate Bulletin Number 07-08-52-001A (Section 08 - Body and Accessories).
Important: This bulletin does not apply to vehicles built after the following dates:
• DTS / Lucerne: 5/1/07 • Impala / Monte Carle: 3/1/07
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 transmitter cannot be programmed. |
• | The remote keyless entry (RKE) and/or remote vehicle start (RVS) transmitter has poor range. |
Any of these concerns may be caused by an internal fault with the transmitters and/or the Remote Control Door Lock Receiver (RCDLR) software/hardware.
Important: This bulletin does not apply to vehicles built after the following dates:
• DTS / Lucerne: 5/1/07 • Impala / Monte Carle: 3/1/07
DO NOT REPLACE THE BCM.
Important:
• The 2006 and 2007 Impala LS without
AP8 does not have a coax antenna. • The 2006 and 2007 Lucerne without
AP3 or AP8 does not have a coax antenna.
1.1. | Remove the driver's side "A" pillar molding and I/P closeout panel. |
1.2. | Unplug the speaker. |
1.3. | To expose the RCDLR antenna, partially remove the driver's side upper I/P closeout panel (near windshield). |
1.4. | Remove the clips holding the RCDLR antenna wire at the RCDLR module and along the "A" pillar. |
1.5. | 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. |
1.6. | Remove the I/P carrier bolt and remove the old RCDLR antenna. |
1.7. | Remove the RCDLR module. |
1.8. | Install the new RCDLR module. |
1.9. | Lay in the new RCDLR antenna and reinstall the carrier bolt. |
1.10. | Connect the new antenna to the RCDLR antenna module. |
1.11. | Clip the new RCDLR antenna into place using the existing holes on the "A" pillar. |
1.12. | Reinstall the I/P close-out panel. |
1.13. | 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. |
1.14. | Reinstall the "A" pillar molding and I/P side closeout panel. |
1.1. | Remove the rear seat cushion. |
1.2. | Remove the rear seat back. |
1.3. | Lower and remove the trunk trim cover to gain access to the underside of the rear package shelf. |
1.4. | Remove the rear seat belts. |
1.5. | Remove the interior C-pillar trim (sail) panels and package shelf. |
1.6. | 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. |
1.7. | Install a new RCDLR module and antenna. |
1.8. | Tape back the harness ground connection. |
1.9. | Reinstall the rear package shelf. |
1.10. | Reinstall the interior C-pillar trim (sail) panels. |
1.11. | Reinstall the rear seat belts. |
1.12. | Reinstall the trunk trim cover. |
1.13. | Reinstall the rear seat back. |
1.14. | Reinstall the rear seat cushion. |
1.1. | Remove left rear C-pillar trim (sail) panel. |
1.2. | 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. |
1.3. | Reinstall the new antenna and RCDLR receiver/module. |
1.4. | Reinstall the C-pillar trim (sail) panel. |
Important: When programming a new or existing RCDLR, the programming instructions in SI must be followed.
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. 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.
Important: Refer to the parts catalog using the VIN of the vehicle being serviced to identify the correct part numbers.
