Normal Operation
WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The stability/traction control switch is hard wired to the Instrument Cluster (IC). Traction control system status is indicated by an indicator in the IC . When the driver deactivates the traction control, the IC sends a message to the PCM and the ABS module over the High Speed Controller Area Network (HS-CAN) bus. The traction control system will remain deactivated until the driver pushes the switch again or until the ignition switch is cycled.
The IC sends a reference voltage to the stability/traction control switch along circuit CCA15 (YE/GY). When the switch is pressed, the reference voltage is momentarily grounded through the switch along circuit GD116 (BK/VT).
- DTC C1093 (Traction Control Disable Switch Circuit Failure) - DTC C1093 will be set if the stability/traction control switch is pressed for more than 2 minutes during normal operation, is pressed at all during the IC
on-demand self test or if there is a short to ground on circuit CCA15 (YE/GY).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Stability/traction control switch
- IC
