Pinpoint Test K : The Traction Control System Is Inoperative Or Cannot Be Disabled: Notes

WARNING: This page is about a different car, the 2016 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

Refer to Instrument Cluster for schematic and connector information.

Normal Operation and Fault Conditions

The traction control switch is used to switch the AdvanceTrac features (traction control, ESC and RSC) on or off. When the driver presses the traction control switch, 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: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .

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: For vehicles equipped with a keyless vehicle system, this test requires the use of at least 2 passive keys programmed to the vehicle; one admin passive key and one restricted passive key.

NOTE: For vehicles not equipped with a keyless vehicle system, this test requires the use of at least 2 Integrated Keyhead Transmitters (IKTs) programmed to the vehicle, one admin IKT and one restricted IKT.
