C0274 GMC - Excessive Dump/Isolation Time
Tech notesIf the C0274 code is combined with other codes, fix other codes first.
C0274 Gmc DescriptionThe 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.
