Normal Operation and Fault Conditions

WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

The traction control switch is used to switch the AdvanceTrac features (traction control, ESC and RSC) on or off. When the traction control switch is pressed, the IPC receives a ground signal from the switch and illuminates the stability-traction control OFF indicator. The IPC sends a traction control switch message to the GWM over the HS-CAN3 and the GWM relays this message to the ABS module over the HS-CAN2. The ABS module takes the necessary action depending on the switch inputs and traction control message. For additional information on disabling AdvanceTrac, refer to the Anti-Lock Brake System (ABS) and Stability Control article, Description and Operation.

NOTE: If equipped, MyKey allows users to configure traction control to be either always on or selectable. If a MyKey restricted key is in use with the MyKey traction control feature configured to always on, traction control cannot be disabled. An admin key must be used to enable and disable traction control.

NOTE: This test requires the use of at least 2 ignition keys (passive or IKT) programmed to the vehicle; one admin ignition key and one restricted ignition key.
