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 following are the supported interface tools:
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.

CONDITION Certain 2013 model year Cadillac ATS and Chevrolet Malibu model vehicles equipped with a 2.0L 4 Cylinder Engine (LTG) may have a condition in which piston damage could occur due to an engine pre-ignition condition. If this condition occurs, the vehicle may perform poorly and oil consumption could increase. A warning light may illuminate indicating an engine misfire. If this repair is not completed before multiple pre-ignition events occur, the piston may be damaged and the engine may need to be rebuilt or replaced. CORRECTION Dealers are to reprogram the Engine Control Module (ECM) with a revised spark control calibration, install spark plugs with a colder heat range (required with the new calibration) and place an update to the spark plug part number information located in the “Maintenance Replacement Parts” found in Section 11 of the Owner Manual. GM will mail the Owner Manual supplement to customers of record. VEHICLES INVOLVED All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle History screen in GM Global Warranty Management system. Dealership service personnel should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs.

For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. Dealers will not have a report available if they have no involved vehicles currently assigned. Page 2 December 2014 Bulletin No.: 14591 The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program. PART INFORMATION Parts required to complete this program are to be obtained from General Motors Customer Care and Aftersales (GMCCA).
