Summary
Service Update - Revised to add Traverse. Certain vehicles may not have the snow/ice mode calibration enabled. This missing calibration results in the selection of snow/ice mode (knob selector) not having a change in the accelerator pedal response. Reprogram the engine control module (ECM).
