Normal Operation and Fault Conditions

On vehicles not equipped with a message center and steering wheel control switches, the traction control switch is used to switch the system on or off and to alert the driver of the traction control system status. The status is relayed to the driver by the traction control switch LED indicator. When the driver presses the traction control switch, the ABS module receives a ground signal from the switch. The ABS module responds by supplying ground to the traction control switch LED indicator.

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.
