Tech notesIf the C0269 code is combined with other codes, fix other codes first.
C0269 Gmc DescriptionThe Electronic Brake Control Module (EBCM) microprocessor grounds the dump coil to energize and close the dump valve. This will release the excessive brake pressure which was applied by the driver to the wheels. If the EBCM microprocessor generates a dump command on one or more wheel for greater than nine seconds, the DTC will set.
