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.
The ignition is ON.
The EBCM detects low voltage on the traction control switch signal circuit for 8 seconds.
• | The EBCM disables the VSES. |
• | The stability indicator turns ON. |
The DTC clears automatically from Current status when the fault is corrected. Use a scan tool to clear the DTC from history status.
Thoroughly inspect connections or circuitry that may cause an intermittent malfunction
Antilock Brake System Schematics
Traction control can be disabled/enabled when the traction control switch is pressed and released.
⇒ | If DTC C0283 does not reset, go to Diagnostic Aids |
⇒ | If DTC C0283 does not reset, replace the traction control switch. |
⇒ | If the DTC C0283 resets, check the TCS/mode switch signal circuit for a short to ground or replace the BCM. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
