ABS BRAKING SYSTEM DIAGNOSIS
WARNING: SOME OPERATIONS IN THIS SECTION
REQUIRE THAT HYDRAULIC TUBES, HOSES AND

TUBE, HOSE OR FITTING. BE SURE THAT THE AC-
CUMULATOR IS FULLY DE-PRESSURIZED AS DE-
SCRIBED IN THIS SECTION. FAILURE TO DE-
PRESSURIZE THE ACCUMULATOR MAY RESULT IN
PERSONAL INJURY AND/OR DAMAGE TO PAINTED
SURFACES.

individually. Attempting to remove or disconnect cer-
tain system components, may result in personal
injury and/or improper system operation. Only those
components with approved removal, service and in-
stallation procedures described in this manual
should be serviced.
