Transfer the selected data to the vehicle’s control module.Ĭaution: Prior to performing SPS, it is important to heed the following precautions:.Check the vehicle’s control module to determine which, if any, calibration file is currently stored.The general three-part process for SPS programming is as follows, regardless of the vehicle involved:
Once you have the VCI number, it must be entered in the entry screen when requested by the SPS. If you need a VCI number, contact your Customer Support Center. An unchecked box on a system tab indicates that a necessary selection has not been made. Each tab is for a distinct calibration file. For many vehicles, you will also need to complete the multiple tab selections. Related bulletin numbers are sometimes listed along with the calibration files.īased on the calibration history and bulletins, select the appropriate calibration file. It is helpful to read the latest bulletins to stay up to date on why certain calibrations have been released. The history lists an explanation of the calibration file, telling what the calibration is for and whether it supersedes any other calibrations. Be sure to check the history of each calibration. You will only see calibrations that are valid for the VIN entered. When reprogramming a vehicle, selecting the correct calibration is critical. Note: If your J2534 device has wireless capability, it is recommended to use the hardwired interface of the programming tool while programming an ECU.
The following are four generally used types of serial communications used with an ECM/PCM controller: The following are the supported interface tools: A Programming Interface tool is your connection between your computer and the vehicle’s J1962 DLC connector for pass-thru programming of the vehicle’s ECUs. To program an ECU, the SPS application must communicate with the vehicle control modules using the proper J2534 programming interface tool. The SPS application is part of the TIS2Web system. When troubleshooting a drivability condition, diagnosis may call for reprogramming the controller with newer calibration information to correct a customer concern. The calibration file contains data such as spark curves and fuel control. The calibration file custom-tailors a module to a certain vehicle.
The Service Programming System (SPS) updates the flash calibration files that are stored in a vehicle onboard controller (e.g.
To familiarize yourself with GDS2 and its capability, and how to use it, please read through the User’s Guide before putting the GDS2 to work. However, the right is reserved to make changes at any time without notice. Every attempt has been made to provide complete and accurate technical information based on factory service information available at the time of publication. GDS2 is designed for use by trained service personnel to diagnose and repair automotive electronic systems. For SPS Pass Through programming with the J2534 interface tool, use the TIS2Web SPS application. Important: SPS programming of vehicle controllers is not supported in GDS2.
