PART INFORMATION
No parts are required.
SERVICE PROCEDURE
Note: Carefully read and follow the instructions below.


Do NOT attempt to order the calibration number from GM Customer Care and Aftersales.
The calibration numbers required for this service procedure are programmed into control
modules via a Multiple Diagnostic Interface (MDI) with the calibration update. Use TIS2WEB
on or after 01/18/14 to obtain the calibration. If you cannot access the calibration, call the
Techline Customer Support Center and it will be provided.



DO NOT program a control module unless directed to by a service procedure or a service
bulletin. If the control module is not properly configured with the correct calibration software,
the control module will not control all of the vehicle features properly.



Ensure the programming tool is equipped with the latest software and is securely connected
to the data link connector. If there is an interruption during programming, programming failure
or control module damage may occur.



Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or
loss of voltage will interrupt programming. When required install the EL-49642 SPS
Programming Support Tool to maintain system voltage. If not available, connect a fully
charged 12 V jumper or booster pack disconnected from the AC voltage supply. DO NOT
connect a battery charger.



Turn OFF or disable systems that may put a load on the vehicles battery such as; interior
lights, exterior lights (including daytime running lights), HVAC, radio, etc.



During the programming procedure, follow the SPS prompts for the correct ignition switch
position.



Clear DTCs after programming is complete. Clearing powertrain DTCs will set the
Inspection/Maintenance (I/M) system status indicators to NO.



Note the engine oil life remaining percentage.

To reprogram an existing K20 Engine Control Module, perform the following procedure:
1. Install EL-49642 SPS programming support tool.
2. Access the Service Programming System (SPS) and follow the on-screen instructions. Refer
to Service Programming System (SPS) documentation in SI for programming instructions.
3. On the SPS Supported Controllers screen, select Engine Control Module - Programming and

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that
may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the tools,
equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to
your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your vehicle may benefit from the information.
