Normal Operation and Fault Conditions
WARNING: This page is about a different variant/trim than selected.
The TCS/Grade Assist is a momentary contact switch located on the selector lever. Pressing the TCS will engage or disengage the O/D function of the transmission. When the O/D is disengaged, the O/D icon will illuminate OFF on the IPC. Each time the ignition switch is cycled, the transmission will automatically provide O/D operation regardless of TCS position the last time the engine was running.
