Diagnostic Information and Procedures
DTC C0283
Circuit Description
The traction control switch is a momentary-contact, normally open switch that can be used to disable the TCS. Each time the traction control switch is pressed, the TCS enabled/disabled status changes. When TCS is disabled, the EBCM illuminates the traction off indicator by opening the service traction control signal circuit.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
The EBCM detects low voltage on the traction control switch signal circuit for 10 seconds.
Action Taken When the DTC Sets
If equipped, the following actions occur:
The EBCM disables the TCS.
The traction off indicator turns ON.
Conditions for Clearing the DTC
The conditions for setting the DTC are no longer present and you use the scan tool Clear DTC's function.
Diagnostic Aids
Thoroughly inspect connections or circuitry that may cause an intermittent malfunction. Refer to Testing for Electrical Intermittents,
Testing for Intermittent and Poor Connections, Wiring Repairs and Connector Repairs in Wiring Systems.
Test Description
The number below refers to the step number on the diagnostic table.
4. This step tests the traction control switch circuitry. If the fuse opens when you perform this test, the traction control switch signal circuit is shorted to ground.
