After Programming A Control Module

WARNING: This page is about a different car, the 2003 Pontiac Grand Prix, 2003 Chevrolet Malibu, and 2003 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.

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.

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 (VTD) password learn procedure.
The Throttle Position (TP) sensor learn procedure.
