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. 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.
HVAC Control Module Programming and Setup
Each of the following service procedures may require programming or setup procedures to be performed on the HVAC control module or HVAC actuators.

Object Alarm Module Programming and Setup
If the object alarm detection module is replaced it must be programmed. Refer to Service Programming System (SPS) .
Passenger Presence System Programming and Setup
| IMPORTANT | Before the passenger presence system (PPS) 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 PPS. When the preload test is perform, the instrument panel cluster (IPC) 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. |
If the PPS is replaced or serviced, perform the preload test procedure for the PPS. Refer to Passenger Presence System Preload Test for the preload test procedure.
Radio Programming and Setup
Each of the following service procedures requires programming or setup procedures to be performed on the radio.
Rear Differential Clutch Control Module Programming and Setup
If the Rear Differential Clutch Control Module is replaced, the following procedures must be performed
- Rear Differential Clutch Control Module Programming-Refer to Service Programming System (SPS) .
- Install a scan tool.
- Turn ON the ignition, with the engine OFF.
- Select Special Functions, Rear Drive System, CCM RDS Matching ID, follow instruction on the Tech 2. The CCM RDS Matching ID number can be found on the CCM harness connector.
- Cycle the ignition OFF, then start the engine and allow to run for 1 minute. Verify the rear differential system is functioning properly.
- After the calibration procedure, clear all DTC, and preform the Diagnostic System Check - Vehicle .
Remote Control Door Lock Receiver Programming and Setup
| IMPORTANT | When replacing the remote control door lock receiver (RCDLR), the tire pressure monitoring (TPM) information can be learned to the new RCDLR in one of two ways. These two methods are reflected in the selections below. Only choose one of the methods; it is not required to do both methods when replacing the RCDLR. If you choose to perform the Copy and Paste TPM Information procedure, Step 1 must be performed BEFORE removing the old RCDLR. This procedure requires that specific TPM information be extracted from the old RCDLR prior to its removal. |
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 customers 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). Due to the time requirements of programming a controller, it is recommended that an external power source be used to maintain system voltage. Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. To ensure trouble-free programming, GM recommends using one of the following external power sources: Midtronic PCS charger A fully charged 12V jumper or booster pack disconnected from the AC voltage supply 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
- FlexFuel (E85) Vehicles The fuel composition learn function is inactive. Programming with the fuel composition learn active will result in fuel trim DTCs. If necessary, drive the vehicle until the scan tool indicates that the fuel composition learn is inactive.
- 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 fully charged before programming the control module. Turn OFF or disable any system that may put a load on the vehicles 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 Heating, ventilation, and air conditioning (HVAC) systems Engine cooling fans, radio, etc.
