Re: ABS accumulator valve relay/ABS bleeding ???

Testing my Bosch relay and the OEM Matsu**** (pretty funny that it deleted the "sh*ta") shows the 87-87a prongs on the Bosch are in continuity as you would expect but the corresponding OEM prongs are NOT... Another question..some manuals say you can bleed the 2 bleeders on the ABS unit just like the brakes(see below)...pump-open-close..while I have read one description where it says you have to cycle the ABS unit (like on newer units) to bleed the ABS unit. Anyone bleed the ABS unit "conventinally" ??

""BLEEDING BRAKE SYSTEM
NOTE: Use FMVSS No. 116, fresh DOT 3 or 4, brake fluid only.
Ensure brake fluid reserve tank never becomes empty. Check
all brake system lines and connections for leaks.
ABS BLEEDING PROCEDURES
1) Using conventional manual brake bleeding method (using
vinyl tubing and container, with foot pressure on brake pedal), follow
sequence in BRAKELINE BLEEDING SEQUENCE table. See Fig. 3 or 4.
2) Attach one end of tubing to bleeder screw and place other
end into container. Have assistant depress and hold pressure on brake
pedal. Open bleeder screw 1-2 seconds and then close it. Release
pressure on brake pedal. Repeat procedure until air has been
discharged from system. See BRAKELINE BLEEDING SEQUENCE table. Bleed
each caliper until air bubbles stop appearing from bleeder tubing in
fluid bottle. Close bleeder screw. ABS system bleeding is completed.
3) When air has been removed from all six connections,
depress brake pedal using about 66 lbs. (30 kg) force and hold it for
about 20 seconds. Check pedal for any unusual movement. Install
wheels. Test drive car for 1-2 miles, ensuring proper operation of
brakes and ABS system.
BRAKELINE BLEEDING SEQUENCE TABLE

Application Sequence
Legacy ......................... (1) HS, RF, LR, (1) HP, LF, RR
SVX ............................ (1) HP, (1) HS, RF, LR, LF, RR
(1) - HP (hydraulic unit primary bleeder between LF and RR);
HS (hydraulic unit secondary bleeder between RF and LR).
