Programming and Setup - All Systems: Diagnosis GMC Acadia I facelift

Diagnostic Aids

1. It is critical to use the service replacement Communication Interface Module only in the vehicle for which it was ordered.
2. Failure to perform the following procedures will result in a red LED, DTC(s) being set and limited or incomplete OnStar® services.
3. An OnStar® button press to the OnStar® call center is not required to complete the procedure.
4. It may take up to 24 hours for OnStar® service to become fully activated after performing the procedures.
5. Perform the following procedure only once. Repeat attempts of the procedure may result in a delay of the activation process.
6. 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.
7. 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.
8. 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.

1. Ignition ON, program the SDM. Refer to «Service Programming System (SPS)»(ref-610060-S12557634442014042100000) .
2. In the BCM Module Setup menu, select Setup SDM Primary Key in BCM. Follow the scan tool on screen instructions.
3. In the SDM Module Setup menu, select Setup SDM. Follow the scan tool on screen instructions.
4. 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-610038-S14557891142014042100000) .

Passenger Presence System Preload Test

The passenger presence system (PPS) consists of an electronic control module, a sensor mat in the seat, a harness and PASSENGER AIR BAG ON/OFF indicators. The passenger presence detection system transmits and receives a low-level electric field. The measured capacitance value of this field is used to determine the type of occupant sitting in the front passenger seat. If the measured capacitance is less than a calibrated value, then the passenger presence module will send a hard wire signal to the inflatable restraint sensing and diagnostic module to disable the passenger instrument panel air bag. If the measured capacitance is greater than a calibrated value, then the passenger presence module will send a serial data signal to the inflatable restraint sensing and diagnostic module to enable the passenger instrument panel air bag. The passenger presence detection system module will notify the customer of the enable/disable status by illuminating one of the PASSENGER AIR BAG ON/OFF indicator. If the passenger seat bottom cushion, seat bottom trim or heater pad has been serviced, reinstalled or removed for any reason, the procedure below will check for any preloads on the passenger presence system. A service replacement passenger presence system module does not require an unlock procedure prior to an initial preload test.

Note. Before the passenger presence system can be checked for preloads the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the passenger presence system. DTC B0081 will set if the preload system test is performed with: An aftermarket seat heater located too close to the sensor mat A scan tool, laptop or other electronic device is in the seat The seat is damp or wet An object or person is in the seat When the preload test is perform, the instrument panel cluster and dash lights will begin illuminating at varying intensity. This is normal operation during the preload test procedure and does not indicate additional system faults. The Diagnostic Repair Verification must be performed after successfully completing the preload test procedure to ensure the system is functioning properly.

Passenger Presence System Preload System Test

1. Empty the front outboard passenger seat (this system is susceptible to conductive material).
2. With the scan tool, perform the Passenger Presence Sensor Learn procedure.
3. Using the scan tool, check for DTC B0081 in history. If the test fails or DTC B0081 11 is current, confirm that the seat is empty. Perform the passenger presence sensor learn test again. If the test fails again, for heated seats, ensure that the sensor pad is on top of the heater element. Once the test successfully completes, cycle the Vehicle OFF.
4. Perform the «Diagnostic Repair Verification»(ref-610038-S02180739412014042100000) after successfully completing the preload test procedure to ensure the system is functioning properly.

1. If programming of the control module is being performed at the direction of a bulletin or PI, follow the instructions provided in that document.
2. 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.
3. 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.
4. The length of time for the USB programming to complete will vary depending on the number and size of the files in the update.
5. 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.
6. 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.
