DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or
control module damage may occur.

If you are performing the pass-through programming procedure using a notebook computer without the power cord, ensure that the internal battery
is fully charged.
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
