DTC Descriptor
DTC C0280: Stability System Active Too LongCircuit/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 switch is in the ON position.
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 turn ON. |
Conditions for Clearing the DTC
| • | The condition for the DTC is no longer present and the DTC is cleared with a scan tool. |
| • | 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.
