* Diagnostic Procedure Instructions (Initial Inspection and Diagnostic Overview)provides an overview of each diagnostic category.

DTC Descriptor
DTC C0280 00
- Stability System Active Too Long

Circuit/System Description

The electronic brake control module (EBCM) detects a malfunction when VSES brake intervention is active for more than an excessive amount of time.

Conditions for Running the DTC

* The ignition is ON.
* The ignition voltage is above 9.5 volts.

Conditions for Setting the DTC

The EBCM detects VSES is active for more than 15 seconds.

Action Taken When the DTC Sets

One or more of the following actions may occur:

* The VSES functionality is disabled
* The TCS/VSES indicators illuminate.

Conditions for Clearing the DTC

* The condition for the DTC is no longer present.
* The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

Diagnostic Aids

* If there are any other DTCs recorded against the dynamic sensor diagnose them first.
* This DTC may be stored as a history DTC without affecting the operation of the module. If stored only as a history DTC and not retrieved as a current DTC, do not replace the module.
* If this DTC is retrieved as both a current and history DTC, replace the yaw rate/accelerometer sensor.
