abs bleeding, clarification?
can someone clarify the below for me? specifically - is it nec to use "special honda tester tool"?
im getting this code, and hoping an abs bleed will work, otherwise, the motor is most likely shot. ive already bled the brake system with no luck, except for improved braking.
this is on a 92 accord, btw.
-----------
A code 1-3 for the pump motor may indicate a failure to build up pressure because the fluid level is low or there is air in the system. There's a special "maintenance bleeder valve" under a red cap on the modulator that must be opened to relieve pressure inside the modulator any time the modulator, pump or accumulator is serviced. Honda has a special T-handle wrench (07HAA-SG00100) that can be used for this purpose. To relieve pressure, turn the bleeder screw one complete turn (key off), then stop. Wait until the pressure is relieved, then close the screw.
If air is trapped inside the ABS modulator, the maintenance bleeder screw can also be used to vent air. But if there's a lot of air inside the solenoid valves, the system will have to be bled using the special Honda ABS tester tool to cycle the solenoids. If you don't have this tool, another method is to manually cycle the solenoids while bleeding the system with a pressure bleeder. To do this, you need a wiring diagram to figure out which terminals on the wiring connector can be jumped to cycle each solenoid one by one.

I think you need it, or something like it. I know someone with an '89 Legend, and that 'tool' lets you run the pump & cycle the valves to work the air out.

On my GS-R you don't have to cycle anything, it just bleeds OK. Newer cars (like my other 3 cars) don't even have an ABS bleed valve or separate reservoir. It all depends on which ABS system is in your car.

I have actually bled brakes while the car was running, thus the booster was helping to force out the fluid. I did this a couple of times and was able to get the air out. Hope this helps.
