Code C0280 Cadillac Description

The solenoid valves are integral parts of the brake pressure modulator. The brake pressure modulator contains an isolation solenoid valve and a dump solenoid valve for each wheel. A traction/stability control supply solenoid valve and an isolation solenoid valve for each brake circuit. The solenoid valves are not engaged during normal system operation. When the ABS, the traction control, or the stability control operation is required the Electronic Brake Control Module (EBCM) turns the required solenoid ON. The Diagnostic Trouble Code (DTC) will be set due to the extended operation of the ABS, the traction control, or the stability control.
