C0275 Gmc Description

The Electronic Brake Control Module (EBCM) microprocessor grounds the isolation coil to energize and close the isolation valve. This will prevent any additional brake pressure applied by the driver from reaching the wheel. Further increases in brake pressure will be prohibited. Each isolation valve is closed independently to isolate each wheel. The EBCM microprocessor also uses software subroutine to monitor for any ABS event which would initiate an isolation command. This subroutine is performed every 1.0 second.
