Caution: During removal and installation, all EPS components including mechanical and/or electrical is extremely susceptible to damage. Dropping or prying on any EPS component may cause internal damage. If damage occurs or a part is dropped, the EPS component must be replaced.

Caution: Care must be taken during removal and installation of the Electronic Power Steering (EPS) components to not hit or break the EPS motor/controller module or module harness connectors. If the EPS motor/ controller module or module connectors are damaged, the complete component must be replaced.

Caution: Electrostatic discharge (ESD) can damage many solid-state electrical components. ESD susceptible components may or may not be labeled with the ESD symbol. Handle all electrical components carefully. Use the following precautions in order to avoid ESD damage:

  • Touch a metal ground point in order to remove your body’s static charge before servicing any electronic component; especially after sliding across the vehicle seat.
  • Do not touch exposed terminals. Terminals may connect to circuits susceptible to ESD damage.
  • Do not allow tools to contact exposed terminals when servicing connectors.
  • Do not remove components from their protective packaging until required to do so.
  • Avoid the following actions unless required by the diagnostic procedure:
    • Jumpering or grounding of the components or connectors.
    • Connecting test equipment probes to components or connectors. Connect the ground lead first when using test probes.
  • Ground the protective packaging of any component before opening. Do not rest solid-state components on metal workbenches, or on top of TVs, radios, or other electrical devices.

Warning: This vehicle is equipped with torque-to-yield or single use fasteners. Install a NEW torque-to-yield or single use fastener when installing this component. Failure to replace the torque-to-yield or single use fasteners could cause damage to the vehicle, component, or bodily injury.

Dealer Responsibility

Whenever a vehicle subject to this Service Update Bulletin enters your vehicle inventory, or at anytime is present for service, you are obliged to take the steps necessary to ensure this Service Update Bulletin correction has been made prior to selling, releasing or returning the vehicle to the customer.


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

Drew Technologies (DRWMONGGM) Mongoose GM Vehicle Interface (VPW/CAN) J2534

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.
