C0280 GMC 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 turns the required solenoid valves ON.
