The USB flash drive should have a USB 2.0 specification with a minimum of 512 MB. Using the USB flash drive reduces the programming time of large calibration files. A USB File Transfer is used to transfer data files from SPS to a USB flash drive, or memory stick.
USB port programming allows for Human Machine Interface (Infotainment, Navigation, XM, and Audio programming) and Instrument Cluster programming.

Always record the SPS Warranty Claim Code on the job card for warranty transaction submission.Refer to the appropriate Programming and Set-up procedures in the Service Information for the control module being programmed for additional information on programming.Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO. Clear Diagnostic Trouble Codes (DTC) after programming is complete.To help avoid damage to vehicle control modules, do not turn off the ignition during reprogramming unless instructed to do so. During the programming procedure, follow the SPS prompts for the correct ignition switch position.Turn off or disable systems that may put a load on the vehicle battery such as: interior lights, exterior lights (including daytime running lamps), HVAC, radio, etc.If the EL-49642 tool is not available, connect a fully charged 12V jumper or booster pack disconnected from the AC voltage supply. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. Maintain stable battery voltage during programming by installing the EL-49642 SPS Programming Support Tool.The MDI 2 has wireless capability however, it is recommended when programming a control module that it is hard wired to the programming tool with the SPS application.If there is an interruption during programming, programming failure or control module damage may occur.

Programming a control module at any other time will not permanently correct a customer concern. Do not program a control module unless directed to by a service procedure or a Service Bulletin.There are a number of steps that should be followed for all programming events Failure to perform all programming actions at the same time on a vehicle may result in additional drivability concerns. These procedures must be completed in the correct order. Review the Control Module References in the Service Information for module-specific programming and related procedures. Based on the control module being programmed, some vehicle modules will require configuration, reset or learn functions to be performed after programming. The Service Information should always be reviewed for the appropriate programming and set-up procedures of an individual module. The programming process uses Pass-Thru Programming through the Multiple Diagnostic Interface tool ( MDI/ MDI 2).īut successful reprogramming of an existing control module as well as programming a new module, including for installation of GM Accessories, requires that the programming process be followed properly every time, including correctly preparing the vehicle for programming, setting up the necessary tools, and reviewing the Service Information. The calibration files contain the data that manage vehicle control functions. It’s becoming second nature for many repairs - reprogramming vehicle control modules with updated calibration files using the Service Programming System (SPS). Something good about successful control module programming for GM vehicles:
