C1294

CIRCUIT DESCRIPTION
This Diagnostic Trouble Code (DTC) occurs when internal self checking safety logic has determined that the Stoplamp switch is continuously on. This is important because the Traction Control System (TCS)/Active Handling (if equipped with RPO JL4) cannot be activated when the Stoplamp switch is on.

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

ACTION TAKEN WHEN THE DTC SETS
Antilock Brake System (ABS) remains enabled, Traction Control System (TCS)/Active Handling (if equipped with RPO JL4) are disabled.
^ Indicators that turn on:
- Car Icon (TCS indicator)
^ Messages displayed on the Driver Information Center (DIC):
- Service Traction System
- Service Active HNDLG (if equipped with RPO JL4)

CONDITIONS FOR CLEARING THE DTC
^ Condition for Diagnostic Trouble Code (DTC) is no longer present and Scan tool clear DTC function is used.
^ Fifty ignition cycles have passed with no DTCs detected.

DIAGNOSTIC AIDS
^ It is very important that a thorough inspection of the wiring and connectors be performed. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction.
^ Possible causes:
- Stoplamp switch circuit shorted to voltage.
- Stoplamp switch misadjusted or shorted.
- Binding pedal.
