Pinpoint Test O: The Traction Control System Is Inoperative Or Cannot Be Disabled Using The Traction Control Switch
WARNING: This page is about a different car, the 2023 Ford Bronco. However, it is still accessible from the selected car via links, so may be relevant.
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.
Normal Operation and Fault Conditions
The traction control switch is part of the Driveline Chassis Switch (DLCS) and is used to switch the traction control feature on or off. When the traction control switch is pressed, the Driveline Chassis Switch (DLCS) sends a traction control switch message to the ABS module over the FD-CAN. The ABS module takes the necessary action depending on the traction control message.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS C1109:24 | Vehicle Dynamics Control Switch: Signal Stuck High | Sets when the message from the Driveline Chassis Switch (DLCS) indicates the traction control switch is pressed in the applied position too long. This is likely due to an internal failure of the switch or the Driveline Chassis Switch (DLCS). |
