GDS2 is designed for use by trained service personnel to diagnose and repair automotive electronic systems. Every attempt has been made to provide complete and accurate technical information based on factory service information available at the time of publication. However, the right is reserved to make changes at any time without notice.
Depending on what access user profile you have and what region you are from, additional icons may appear. The Service Programming System SPS updates the flash calibration files that are stored in a vehicle onboard controller e. The calibration file custom-tailors a module to a certain vehicle. The calibration file contains data such as spark curves and fuel control. When troubleshooting a drivability condition, diagnosis may call for reprogramming the controller with newer calibration information to correct a customer concern.
To program an ECU, the SPS application must communicate with the vehicle control modules using the proper J programming interface tool. Note: If your J device has wireless capability, it is recommended to use the hardwired interface of the programming tool while programming an ECU.
When reprogramming a vehicle, selecting the correct calibration is critical. You will only see calibrations that are valid for the VIN entered. Be sure to check the history of each calibration. The history lists an explanation of the calibration file, telling what the calibration is for and whether it supersedes any other calibrations. It is helpful to read the latest bulletins to stay up to date on why certain calibrations have been released.
Related bulletin numbers are sometimes listed along with the calibration files. Based on the calibration history and bulletins, select the appropriate calibration file. For many vehicles, you will also need to complete the multiple tab selections. Each tab is for a distinct calibration file. An unchecked box on a system tab indicates that a necessary selection has not been made. The general three-part process for SPS programming is as follows, regardless of the vehicle involved:.
Pass-thru programming requires that the Scan Tool remain connected to the terminal and to the vehicle throughout the programming process. The vehicle must be in close proximity to the terminal while using pass-thru programming.
Note: In order to reduce the potential for signal loss, the J interface tool should be configured for the most stable communication option at your location.
Note: The J interface tool may have wireless capability, however it is recommended when using a programming interface tool to program an ECU that it is hardwired to the programming tool which contains the SPS application.
The current calibration is displayed along with the new calibrations available for the selected vehicle. Forums Search forums.
