UART (Universal Asynchronous Receive and Transmit) 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. Record or display history of the previous vehicle diagnostic sessions.ĭepending on what access user profile you have and what region you are from, additional icons may appear. Read VIN, ECU part numbers and software numbers.Ĭontrol and monitor Output Control functions.
Read codes, code status, Freeze Frame data and Clear Codes. GDS2 provides the following capabilities in multiple languages: 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.
