Testing conducted by GM and GM’s supplier found that, under certain conditions, software in the FCM may improperly detect an obstacle, which can lead to initiation of an unwarranted AEB event. GM’s investigation included detailed comparative analysis of the relevant field data relating to different versions of the FCM software, vehicles built in different production periods, and vehicles in the U.S. and China. GM’s analysis found 234 field complaints in the U.S. potentially related to this condition, which were received by GM between November 29, 2022, and February 6, 2024. Of these claims, four involved accidents and three involved minor injuries.

On February 15, 2024, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall.

Reprogramming

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 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.
