Pinpoint Test P : The Traction Control System Cannot Be Disabled - Vehicles Equipped With A 1.6L GTDI Engine: Notes
Refer to Vehicle Dynamic Systems for schematic and connector information.
Normal Operation and Fault Conditions
The stability / traction control OFF indicator (sliding car OFF icon) in the IPC provides traction control system status to the driver. When the driver deactivates the traction control using the stability / traction control switch, the ABS module continues to monitor for excessive wheel spin, but no longer takes any action when a traction event is detected.
When the traction control system is deactivated, the ABS module sends a message to the IPC over the HS-CAN to illuminate the stability / traction control disabled indicator (sliding car OFF icon). The IPC responds by illuminating the stability / traction control disabled indicator (sliding car OFF icon). The traction control system remains deactivated until the driver changes the traction control state using the switch or until the ignition is cycled.
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 AdvanceTrac ® always on feature configured to on, the traction control system cannot be disabled. An admin key must be used to enable and disable the traction control system.
