Question about 1993 Chevrolet Suburban
Most abs faults start at the sensors in the wheels
can be dirt or other material between the sensor and the rotor, broken wiring, missing wiring, faulty wheel bearings allowing the rotor to touch the sensor tip
there is no real necessity for abs system as the antiskid action is only there to allow steering control under heavy braking
for easy stopping and moderate braking , it doesn't work.
it is an electronic controlled pump that maintains line pressure to foot brake pressure for when a wheel stops turning , the valve releases the ;line pressure for a split second and then reapplies the line pressure when wheel rotation is again recorded
get yourself a workshop manual for the vehicle ( any gm product ( suburban , s10, blazer ) will have the same system installed and the principle of operation is the same for all manufacturer models

i recomend getting a book from the auto parts store. it will have all the electrical diagrams. it costs less than $20.00 and will be a good investment. i have a book for all my cars and have never had to go to a shop.

Both show as trans codes in my book. #73= Pressure Control Solenoid"If return amperage varies more than 0.16 amps from command amperage" and # 86 =Low Ratio, and this one has no definition. and they are listed under 96 disel W/4L80E and 94 gasW/4L60E.Well hope this helped.
