GM Diagnostic/Programming (TIS2Web)

Approved J2534 Device with TIS2WEB can reprogram 1996 and later All GM Modules.

To obtain the latest electronic controller calibration information for your vehicle, go to https://tis2web.service.gm.com/tis2web and enter the vehicle’s 17 character Vehicle Identification Number (VIN) and select ‘Get CAL ID’.

You can then compare the latest part number with the actual number installed on the vehicle to determine if a reprogram is needed.

The Service Programming System (SPS) application is part of the TIS2Web system. To program an ECU, the SPS application must communicate with the vehicle control modules using the proper J2534 programming interface tool.

The following are the supported interface tools:

OEM GM Tech 2 Dealer Package
Bosch GM MDI 2 (2nd Gen) MDI2 interface

Bosch EL-52100-AM GM Multiple Diagnostic Interface 2 (MDI 2) Kit

CarDAQ-Plus 2 Diagnostic Code Reader and J2534 Programming Tool

Drew Technologies (DRWCDPLUSKIT) CarDAQ-Plus J2534 Flash Reprogramming Kit
Drew Tech CarDaq-M 2 SAE J2534-1/2 Reflash Reprogramming Tool OEM Diagnostics

VSI J2534 ECU Reprogrammer & Diagnostic Adapter
Autel (AULMF2534) MaxiFlash Pro
Dearborn d-Bridge Adapter J2534 OBDII Engineering Tool

The Tech 2 supports model years 1996 and beyond. With the addition of the CAN Diagnostic Interface (CANdi) module, Tech 2 is fully backward compatible with current Tech 2 functionality and operates transparently when diagnosing non-CAN-equipped vehicles.

Servicing the next generation Global A vehicles will require the diagnostic software, GDS2, Global Diagnostic System 2 running on a local PC device while the MDI is connected to the vehicle.

The GM MDI is the Global Diagnostic tool for future vehicles starting with Global A vehicles. The GM MDI was introduced in the fall of 2007 for Pass-Thru programming and offers faster programming speed. It can be used to perform Pass-Thru programming on all vehicles built since 1996 and into the future. Click here to view a list of GDS supported vehicles.
