If the module experiences an electrical short, the vehicle could display a check engine light, stall, or fail to start.

If the vehicle experiences this condition and stalls while in motion, there could be an increased risk of a vehicle crash.

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.

  1. My 2014 Chevy Silverado is having this exact issue, but the issue does not come up when I type in the VIN.

    My call stalled in the middle of the road this past Memorial Day Weekend, and I almost died. Total power failure–could not turn on the hazards or open the door–and was nearly T-boned.

    Have called GM every day since, and have been given the complete runaround. Have taken the car to 3 different Chevy dealers/repair shops, paid the diagnostic fee each time, only to be told that they could not duplicate the issue.

    I have been loyal to Chevy, and have only bought Chevy. I expected better than this, and now just hope that my loyalty does not result in my preventable death.

    Please help.

  2. My 2009 Chevrolet Silverado 1500 is having a problem that the electric goes off and on when driving on the highway after hitting the brake pedal. This is intermittent and does not happen all of the time. It seems very dangerous, sometimes when it happens the door locks go up and down. I talked to the Chevrolet dealer in Tempe, Freeway Chevrolet, and they stated this was not part of this recall. I would think that Chevrolet would be glad to fix it before a crash, sort of like Toyota should of fixed their braking and acceleration problem before so many crashes. Is it true that even if the truck is having the same problem as the recall, which is a safety recall, it may not be covered for it is not listed?

  3. I Have a 2008 Chevrolet 2500 HD Duramax that gets a service trailer brake system once in awhile (Sometimes when connected to trailer, sometimes not) I had my dealer check #14515b recall. He said it didn’t involve my vin. How is it determined which vin is involved?
