Service Programming System Pass-Thru Procedure: Notes

WARNING: This page is about a different variant/trim than selected.
NOTE: The TIS supports service programming using the Tech 2® scan tool only.

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.
