Ensure the programming tool is equipped with the latest software and is securely connected to the Data Link Connector.If the Same Calibration/Software Warning is noted on the SPS Controller screen, do not attempt to program the module. GM does not recommend reprogramming with the same calibration.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. 13) 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. 12) The calibration files contain the data that manage vehicle control functions.
