What is Pass-Thru programming?
If you’re trying to program a module, there are two methods. One is pass-through and the other is using the Tech 2 as a go-between.
Pass-thru programming allows the scan tool to remain connected to the terminal and to the vehicle throughout the programming process. The vehicle must be in close proximity to the terminal while using pass-thru programming
IMPORTANT: TIS2000 supports Service Programming with the Tech 2 scan tool only
Note: Tech2 pass-through or go-between Method:

This number may be obtained from the Techline Customer Support Center. The correct tire size and axle ratio must be highlighted and a valid VCI number entered if you select Reconfigure for your programming type. Select Cancel if you receive a message stating that the calibration selected is already the current calibration in the control module and reprogramming with the same download is not allowed.
Enter a valid VCI number for this vehicle (obtained from Customer Support) and select OK.
Select the correct tire size and axle ratio, then select OK. The VCI number entry box appears. Enter a valid VCI number for this vehicle and select OK.
IMPORTANT: Some vehicles will require that Idle Learn, TP Learn, Theft Deterrent Relearn, or Crankshaft Variation Learn procedures be performed after programming. Consult the appropriate service information for these procedures
