C0283

DTC C0283

Circuit Description

The mode switch is a momentary-contact, normally-open switch that can be used to disable the vehicle stability enhancement system (VSES). The mode switch is directly monitored by the electronic brake control module (EBCM). Each time the mode switch is pressed, the VSES enabled/disabled status changes. When VSES is disabled, the EBCM sends serial data messages to the instrument panel cluster (IPC) to turn ON the stability indicator.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC C0283 Mode Switch Circuit Malfunction

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 8 seconds.

Action Taken When the DTC Sets

^ The EBCM disables the VSES.
^ The stability 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 DTCs function.

Diagnostic Aids

Thoroughly inspect connections or circuitry that may cause an intermittent malfunction. Refer to Testing for Electrical Intermittents, Testing for Intermittent Conditions and Poor Connections, Wiring Repairs, and Connector Repairs.

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.
