Service Programming System (SPS)
For step by step programming instructions, please refer to the Techline Information System (TIS) terminal.
Review the information below to ensure proper programming protocol.
| IMPORTANT | DO NOT program a control module unless you are directed by a service procedure or you are directed by a General Motors Corporation service bulletin. Programming a control module at any other time will not permanently correct a customer's concern. It is essential that the Tech 2 and the TIS terminal are both equipped with the latest software before performing service programming system (SPS). Some modules will require additional programming/setup events performed before or after programming. Some vehicles may require the use of a CANDi module for programming. Review the appropriate service information for these procedures. DTCs may set during programming. Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO. |
Ensure the following conditions are met before programming a control module
- Vehicle system voltage There is not a charging system concern. All charging system concerns must be repaired before programming a control module. Battery voltage is greater than 12 volts but less than 16 volts. The battery must be charged before programming the control module if the battery voltage is low. A battery charger is NOT connected to the vehicle's battery. Incorrect system voltage or voltage fluctuations from a battery charger, may cause programming failure or control module damage. Turn OFF or disable any system that may put a load on the vehicle's battery, such as the following components: Twilight sentinel Interior lights Daytime running lights (DRL)-Applying the parking brake, on most vehicles, disables the DRL system. Refer to the Owner's manual. Heating, ventilation and air conditioning (HVAC) systems Engine cooling fans, radio, etc.
- The ignition switch must be in the proper position. The Tech 2 prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so.
- Make certain all tool connections are secure, including the following components and circuits: The RS-232 communication cable port The connection at the data link connector (DLC) The voltage supply circuits
- DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.
- DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. Attempt to reprogram the control module. If the control module cannot be programmed, replace the control module.
Audio Amplifier Programming and Setup
There is no setup procedure that needs to be performed for the amplifier on this vehicle.
Programming the BCM
| IMPORTANT | The vehicle will not start and many other functions may not operate properly if a replacement BCM is not properly set up. The following procedures must be followed |
- Programming the BCM
- Learning the restraints ID
| IMPORTANT | After the procedure is completed, the personalization settings of the BCM are set to default settings. Inform the customer that the personalization must be set again. |
Learning the Restraints ID
Navigate on the scan tool to Body Control Module > Module Setup > Setup SDM Primary Key in BCM, then follow the instructions on the screen.
| IMPORTANT | After programming, perform the following to avoid future misdiagnosis |
- Turn the ignition OFF for 10 seconds.
- Connect the scan tool to the data link connector.
- Turn the ignition ON, with the engine OFF.
- Use the scan tool in order to retrieve history DTCs from all modules.
- Clear all history DTCs.
Communication Interface Module Programming and Setup
Each of the following service procedures require programming or setup procedures to be performed on the communication interface module.
Digital Radio Receiver Programming and Setup
Each of the following service procedures requires programming or setup procedures to be performed on the digital radio receiver.
EBCM Reprogramming
If the EBCM needs to be reprogrammed, refer to Service Programming System (SPS) .
Engine Control Module Programming and Setup
The following service procedures require either a programming or a setup event performed for a complete repair.
ECM Reprogramming
- If the ECM needs to be reprogrammed, refer to «Service Programming System (SPS)»(ref-275033-S38300901262007122600000) .
- Engine Oil Life Remaining-When available, use a scan tool to reset the Engine Oil Life Remaining back to the original percentage recorded before the module was reprogrammed.
- Turn the ignition OFF for 30 seconds.
- Turn the ignition ON with the engine OFF.
- Use the scan tool in order to retrieve history DTCs from all modules.
- Clear all history DTCs.
HVAC Control Module Programming and Setup
Each of the following service procedures requires programming or setup procedures to be performed on the HVAC control module.
Inflatable Restraint Vehicle Rollover Sensor Programming and Setup
- Key ON, Engine OFF. With the scan tool perform the Setup New ROS procedure for the inflatable restraint vehicle Rollover Sensor (ROS).
- Key OFF then ON again. Clear all codes and verify no current faults are present.
Instrument Cluster Programming and Setup
This device requires no programming or setup.
Passenger Presence System Programming and Setup
| IMPORTANT | Before rezeroing the passenger presence system (PPS), 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 PPS. When rezeroing the PPS, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the rezeroing procedure and does not indicate additional system faults. |
If the PPS is replaced or serviced, perform the rezeroing procedure for the PPS. Refer to Passenger Presence System Rezeroing for the rezeroing procedure.
Radio Programming and Setup
Each of the following service procedures require programming or setup procedures to be performed on the radio.
Sunroof Control Module Programming and Setup
This device requires no programming or setup.
Theft Deterrent Control Module Programming and Setup
- Connect a scan tool to the vehicle in the Pass-thru arrangement.
- Turn ON the ignition, with the engine OFF.
- Ensure that all power consuming devices are turned OFF on the vehicle.
- On the Techline Terminal, select Service Programming System and follow the Techline Terminal on-screen instructions, using the Legacy Pass-Thru method. Ensure the correct programming selection is chosen based on component being replaced or programmed as outlined in the TDM - Theft Deterrent Module menu and select the proper on-screen options.
- After the programming has completed, turn the ignition OFF for 30 seconds.
- Turn ON the ignition with the engine OFF.
- On the Techline Terminal, select Service Programming System and follow the Techline Terminal on-screen instructions, using the Legacy Pass-Thru method. Ensure the correct programming selection is chosen based on component being replaced or programmed. For this procedure, go to the V.T.D. Vehicle Theft Deterrent Learn menu and choose the Vehicle Theft Deterrent Learn, ECM, or PK3 Replaced selection.
- At this point the scan tool must remain connected for the duration of the 10-minute relearn procedure.
- Observe the scan tool, after approximately 10 minutes the scan tool will display "Programming Successful, Turn OFF Ignition". The vehicle is now ready to relearn the key information and/or the passwords on the next ignition switch transition from OFF to CRANK.
- Turn OFF the ignition and wait 2 minutes.
- With a master vehicle key, turn the ignition to the RUN position for 15 seconds, then start the vehicle. The TDM and ECM have now relearned the pre-release password and the challenge/response data.
- With a scan tool, clear any DTCs.
