After Programming A Control Module

The powertrain may operate slightly different after a control module software/calibration update. Operating the powertrain through various driving conditions allows the control module to re-learn certain values. The control module must re-learn the following after a software/calibration update:
^ Fuel trim correction
^ Idle Air Control (IAC) learned position
^ Automatic transmission shift adapts

Other learned values only re-learn by performing a service procedure.

If a control module is replaced the following service procedures may need to be performed:
^ The crankshaft variation learn procedure
^ The engine oil life reset procedure
^ The idle learn procedure
^ The inspection/maintenance complete system set procedure
^ The vehicle theft deterrent password learn procedure
^ The Throttle Position (TP) sensor learn procedure
