It is essential that the TIS terminal, MDI, and/or Scan Tool, is equipped with the latest software before performing service programming. Due to the time requirements of programming a controller, install EL-49642 SPS Programming Support Tool to maintain system voltage. Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. If the above tool is not available, DO NOT connect a battery charger, connect a fully charged 12V jumper or booster pack disconnected from the AC voltage supply. Some modules will require additional programming/setup events to be performed before or after programming. Some vehicles may require the use of a CANDi or MDI 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 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: Interior lights Exterior lights including 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. SPS 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: Scan Tool The RS-232 communication cable port The connection at the data link connector (DLC) The voltage supply circuits MDI The USB, Ethernet or Wireless communication port The connection at the data link connector (DLC)
- DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.
In the event of an interrupted or unsuccessful programming event, perform the following steps
- DO NOT turn the ignition OFF. 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 can still not be programmed, turn the ignition OFF for at least one minute.
- Turn the ignition ON and attempt to reprogram the control module. The control module should program. If the control module still cannot be programmed, replace the control module.
After successfully programming the control module, ensure that all post programming procedures are performed; refer to Control Module References for the appropriate control module Programming and Setup document for any required procedures.
Sunroof Control Module Programming and Setup (Tilt and Slide System)
When replacing the sunroof motor/control module, the sunroof motor/actuator initialization/teach procedure must be followed.
Initialization and Learn Procedures
In order for the sunroof system to perform correctly it needs to establish its position and the force profile it will encounter under normal closing conditions. These two procedures need to be run when a new controller is placed on a vehicle, when a service procedure is performed on any mechanical component, or if the system seems to lose track of its known position.
Initialization and Reinitialization
When the sunroof controller is not initialized it will perform all 'Open' requests, but no 'Express close' or LIN-Bus communicated close commands. It will only perform a 'Close' operation requested by the switch with obstacle detection disabled. If an initialization procedure is interrupted the controllers will return to the not initialized state. Which procedure is run depends on the state of the controller.
For a module which is not initialized begin the process by holding the sunroof switch in the 'Close' position. The sunroof will move to the end of physical travel in the closed direction and store that position. During this time it is necessary to keep the switch active until the process completes. At the completion of the procedure the sunroof should back off slightly to its soft stops. The rest of the defined positions are determined by offsets from this home position.
For a module which has been previously initialized release the switch after the sunroof is considered fully closed by the software. Then hold the sunroof switch in the closed position for 10 s. The sunroof shall resume motion in the 'Close' direction until the end of travel is detected. During this time it is necessary to keep the switch active until the process completes. At the completion of the procedure the sunroof should back off slightly to its soft stops.
For learning the force profile for anti-pinch algorithm after initialization or re-initialization move the roof to the fully open position and release the switch. Activate the 'Open' function of the switch continuously for more than 15 s. At this point, the sunroof will automatically begin to move to the fully closed position. During this time it is necessary to keep the switch active until the process completes.
