Circuit Description

The antilock brake system (ABS)/traction control system (TCS) module sends serial data along the secondary serial data bus, circuit 1061. This is read by the instrument cluster to indicate the status of the traction control. If traction control has been disabled by the ABS/TCS module, the Traction Control Off warning will appear on the instrument cluster multifunction display (MFD). DTC 8 will set if there is no ABS data message on the bus for more than 10 seconds. In practice the trouble code is set somewhere between 10 and 20 seconds after the last ABS data message is received by the instrument cluster. The DTC is reset within 10 seconds of the arrival of an ABS data message on the bus. The DTC is logged as a History DTC.
