SECTION VIIC SERVICE PROGRAMMING SYSTEM
2005 Tech 2 User’s Guide VII - 57
11. On the Supported Controllers screen (Figure VIIC-5), select the type of programming to be performed
from the following categories:
• Normal – Used for updating an existing calibration or programming a new controller
• VCI (Vehicle configuration index) – Used for updating an existing controller or programming a new
controller for newer vehicles whose VINs are not yet in the database
• Reconfigure – Used to reconfigure a vehicle for changes in tire size and axle ratios
• Select Next.
12. A Calibration Selection screen will appear showing the calibration to be used (Figure VIIC-7). Make a
calibration selection, if necessary. When all calibrations are selected, a green check mark will appear
on each folder tab. Select Next.
13. A Summary screen will appear that summarizes the current and selected calibrations of the control
module (Figure VIIC-9). Confirm your choices, then select Next.
Note: If calibrations are the same, the NAODRUI Control box appears (Figure VIIC-10) stating that
the calibrations selected are already the current calibrations in the control module. Click OK.
14. A Transfer Data screen will appear (Figure VIIC-11). The PC will automatically load the calibration into
the Tech 2.
15. After the download is complete, a Program Controller screen appears (Figure VIIC-36). Follow the
on-screen instructions (if any), then select Close, power down and disconnect the Tech 2 from the PC.
Note: Most GM vehicles require you to perform the crankshaft position variation relearn procedure.
