Information

The service programming system team has made an update to SPS which will prohibit or warn against programming a control module with the same calibration already present in the controller. This condition may be caused by the change to the programming system made in an attempt to reduce unneeded programming events, reduce risk of programming induced faults, and support timely vehicle repair. Programming a control module with the salemarks Chevrolet (GM Korea) and Chevrolet (Holden) and with the same calibration already in the module, will be prohibited. If you attempt to reprogram a module with its current calibration you will be prompted with the above warning message. You will not be allowed to redundantly reprogram the module. This message does Not indicate an issue with the module in question - pursue SI diagnostics for further root cause determination.
