Diagnostic Instructions
DTC Descriptor
DTC C0280 00: Stability System Active Too Long
Circuit/System Description
The solenoid valves are integral parts of the brake pressure modulator valve assembly. The brake pressure modulator valve assembly contains an isolation solenoid valve and a dump solenoid valve for each wheel and a traction control/stability control supply solenoid valve and isolation solenoid valve for each brake circuit. The solenoid valves are not engaged during normal system operation. When the ABS, traction control or stability control operation is required the electronic brake control module (EBCM) turns the required solenoid valves ON.
Conditions for Running the DTC

Conditions for Setting the DTC
Stability control is active for more than 15 s.
Action Taken When the DTC Sets
• | The EBCM disables the stability control for the duration of the ignition cycle. |

Circuit/System Testing
- Ignition ON, verify that DTC C0186, C0196, C019B, or C0710 is not set as a present DTC.
- Inspect the B99 Steering Wheel Angle Sensor and B119 Multi-axis Acceleration Sensor for correct installation.
⇒ | If loose or incorrect installation is diagnosed, correct the installation of the component. |
- Ignition ON, verify that DTC C0280 00 is not set as a present DTC.
⇒ | If DTC C0280 00 is present, replace the K17 Electronic Brake Control Module (EBCM) and verify DTC does not reset. If the DTC resets replace the brake pressure modulator valve assembly. |
