Diagnostic Aids
- 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 In open sky condition at speeds greater than 10 mph (16 kph) or more for a minimum of 5 miles (8 km) and perform at least 2 left and 2 right 90 degree turns coming to complete stops prior to each turn.
- 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.
Inflatable Restraint Sensing and Diagnostic Module Programming and Setup
Note. The air bag indicator light may remain ON after the body control module (BCM) or inflatable restraint sensing and diagnostic module (SDM) is replaced and during the programming procedure for the BCM until after the procedure is completed. When installing a new SDM, there may be several DTCs set prior to programming. Once programmed, these DTCs should be in history and can be cleared.
- Ignition ON, program the SDM. Refer to «Service Programming System (SPS)»(ref-611721-S36131310942014042500000).
- In the BCM Module Setup menu, select Setup SDM Primary Key in BCM. Follow the scan tool on screen instructions.
- In the SDM Module Setup menu, select Setup SDM. Follow the scan tool on screen instructions.
- Cycle the ignition from OFF to ON. Verify no DTCs are set. If any DTCs are set, refer to «Diagnostic Trouble Code (DTC) List - Vehicle»(ref-611699-S32368168712014042500000).
- If programming of the control module is being performed at the direction of a bulletin or PI, follow the instructions provided in that document.
- During audio system programming you may be required to select multiple calibrations dependent upon vehicle equipment. Have the vehicle build/RPO information available during the following procedure to ensure the correct calibrations are selected.
- Dependant upon vehicle equipment, the current software level of the module or the release of updates, USB programming may not be required when replacing/reprogramming the control module. If USB files for the application are not available via SPS or have not been received from General Motors in another manner of distribution, the USB update process will not need to be performed.
- The length of time for the USB programming to complete will vary depending on the number and size of the files in the update.
- All data will be erased from the USB device BEFORE the calibration is downloaded onto the device. To ensure important information is NOT erased, always verify that NO information is stored on the device BEFORE beginning the calibration download. If required, transfer important files to another storage device BEFORE beginning the calibration download.
- The XM satellite radio (if equipped) is integrated into the radio. If XM was activated in the previous radio, the replacement radio will require no additional activation steps. Customer subscription information is transferred to the replacement radio when a replacement radio is ordered.
