Traction Off Indicator Always On

Circuit Description
The Traction Oft indicator is controlled by the instrument cluster via serial data messages from the EBCM. When the RIM sees the traction control switch input grounded through the momentary traction control switch, it sends a serial data message to the EBCM that tells the EBCM that the traction control switch has been pressed. The EBCM then disables traction control and sends a serial data message to the instrument cluster to turn on the Traction Off indicator on the instrument panel. Each time the ignition is cycled from OFF to ON, the traction control system is enabled.
