Communication Interface Module Replacement

Note. It is critical to use the service replacement Communication Interface Module only in the vehicle for which it was ordered. Failure to perform the following procedures will result in a red LED, DTC(s) being set, and limited or incomplete OnStar® services. An OnStar® button press to the OnStar® call center is not required to complete the procedure. It may take up to 24 hours for OnStar® service to become fully activated after performing the procedures. Perform the following procedure only once. Repeat attempts of the procedure may result in a delay of the activation process. To fully activate an OnStar® module, both the setup and activation request procedures must be completed on all vehicles with and without an active OnStar® subscription to insure the unit has been setup properly for the vehicle it has been installed into and also to update the OnStar® with the correct unit information. To initialize the Turn-by-Turn feature, the vehicle must first be driven 8-16 km (5-10 mi) in order to allow the system to self-calibrate the dead reckoning feature. On vehicles up fitted with TTY capabilities, it is necessary to perform a power cycle of the OnStar® Interface Module (OTIM), and toggle the TTY mode after completing the Communication Interface Module installation and setup procedures.

Remote Control Door Lock Receiver Replacement - Copy and Paste TPM Information

This procedure will learn the TPM information to the new RCDLR using the Copy and Paste function on the scan tool. This procedure will extract the TPM Tire Type information as well as the sensor data from the existing RCDLR prior to its replacement and store this information in the scan tool. After RCDLR replacement and SPS programming, the tire type and sensor data stored in the scan tool is written to the new RCDLR, negating the need to perform the tire type setup and sensor learn procedure.

This procedure should be considered as the first programming choice when replacing an RCDLR. The Copy and Paste procedure eliminates the possibility of incorrectly inputting the tire type or learning stray TPM sensors.

1. Using a scan tool, navigate to the Copy and Paste TPM Information procedure and copy the existing TPM information from the RCDLR using the outline below. Follow the on-screen instructions after selecting Step 1: Vehicle Control Systems Module Setup Remote Control Door Lock Receiver Copy and Paste TPM Information Step 1
2. At this point, install the new RCDLR.
3. Program the RCDLR - Refer to «Service Programming System (SPS)»(ref-478463-S04899301762012061100000) .
4. Using a scan tool, navigate to the Copy and Paste TPM Information procedure to paste the stored TPM information using the outline below. Follow the on-screen instructions after selecting Step 2: Vehicle Control Systems Module Setup Remote Control Door Lock Receiver Copy and Paste TPM Information Step 2
5. Program the keyless entry transmitters - Refer to «Remote Control Door Lock Transmitter Learn»(ref-478468-S06309334202012061100000) .

Remote Control Door Lock Receiver Replacement - TPM Sensor Learn

This procedure will learn TPM information to the new RCDLR by manually inputting the tire type using the scan tool and performing the TPM sensor learn. This procedure should be performed if the above Copy and Paste procedure can not be completed. An example of this would be an RCDLR that is unable to communicate with the scan tool and is required to be replaced.

1. RCDLR Programming - Refer to «Service Programming System (SPS)»(ref-478463-S04899301762012061100000) .
2. Keyless Entry Transmitter Programming - Refer to «Remote Control Door Lock Transmitter Learn»(ref-478468-S06309334202012061100000) .
3. Tire Type Setup: Install a scan tool. Select Remote Control Door Lock Receiver under Module Setup in the Vehicle Control System menu. Select Tire Type/Pressure Selection. Follow the on-sceen instructions.
4. Tire Pressure Monitoring Sensor Learn - Refer to «Tire Pressure Indicator Sensor Learn»(ref-478511-S16551873692012061100000) .
