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.
