C1294

CIRCUIT DESCRIPTION
This Diagnostic Trouble Code (DTC) occurs when the internal self-checking safety logic has determined that the Stoplamp/BTSI switch is continuously on. This is important because the Traction Control System (TCS) cannot be activated when the Stoplamp/BTSI switch is on.

CONDITIONS FOR SETTING THE DTC
A DTC C1294 can be set if the vehicle speed reaches at least 40 km/h (25 mph). A malfunction exists if the brake was never off during two consecutive drive cycles.

ACTION TAKEN WHEN THE DTC SETS
^ A DTC C1294 is stored
^ The TCS is disabled
^ The TRACTION OFF indicator is turned on
^ The ABS remains functional

CONDITIONS FOR CLEARING THE DTC
^ The condition for the DTC is no longer present and the scan tool clear DTC function is used
^ 50 ignition cycles have passed with no DTCs detected

DIAGNOSTIC AIDS
^ Thoroughly inspect the wiring and the connectors. Failure to carefully and fully inspect the wiring and the connectors can result in misdiagnosis. Misdiagnosis may cause replacement of parts without repairing the malfunction.
^ The following conditions may cause most intermittent malfunctions:
- Poor connections
- Rubbed through wire insulation
- A broken wire inside the insulation
^ The following conditions are other possible causes of this malfunction:
- A short to voltage in the Stoplamp/BTSI switch circuit
- A misadjusted or shorted Stoplamp/BTSI switch
^ If an intermittent malfunction exists, refer to Troubleshooting Procedures.
