So I broke the wire going to passenger side wheel. (The wire for abs, what’s it called the VSS or something like that?) My abs light was on, replaced wire, abs light still on. So tonight I check the code. And it’s just a 1. I looked in the manual and 1 = abs pump motor over run (page19-56). Looking at the flow chart (page 19-57 – 58) its could be 1) I need to bleed air from antilock brake system, 2) Faulty ABS pump motor 3) faulty solenoid (leakage) replace the modulator unit 4) replace the pressure switch.

My guess, and hope, is that I need to bleed the air. I am looking at the process on page 19-86. Do I really need all them special tools? Is this a project I can do on my own, or with someone helping me?

Thanks

did you reset your ECU?

Following the flow chart on page 19-57 here is what I did.

-Bleed high-pressure fluid from the maintenance bleeder with the bleeder t wrench. I did not do this due to lack of bleeder t wrench.

-Remove the abs pump motor relay

-Connect the #29 and 30 terminals using a jumper wire for about eight seconds. I did this.

-Does the abs pump motor run with an increasingly loud raspy sound? Yes or no.
No mine ran relatively quietly, and it did not increase in sound.

-Pump runs with a constant soft sound: bleed air from anti-lock brake system using the procedure on page 19-86 and check the pump sound again.

Following reading the directions on page 19-86 it talks about an ALB checker. Is this something that only a shop will have or can I pick one up at the local auto parts store?

Thanks!

You dont need the ALB checker or the T- wrench to check/bleed the pump!

IABS pump motor relay: How to check
make sure ignition is switched off
remove the pump motor relay
place ohmmeter probes between relay terminals C and D
ohmmeter will read infinity (open circuit) if good
whilst ohmmeter still connected, apply 12 volt supply to replay terminals A and B
ohmmeter will read zero (continuity) if good
if readings are different from above relay might be defective.


ABS pump motor: How to check

IT IS IMPORTANT not to force the pump to run for more than 10 seconds
check fuse for pump motor
check ABS pump relay as previously described
if these prove ok remove pump relay
join pump relay female terminals 1 and 2 with a bridge wire
pump motor should run and begin to labour quickly
if motor is not running apply 12 volts directly to the 2 pin large orange connector plug
if motor is not running, replacement pump is required


How to bleed ALB2 hydraulic system without Honda/Rover tools

upon replacing pump top brake fluid resevoir up to maximum level
with modulator bleed valve open and a pipe to safely channel fluid to a container,
bridge the pump motor relay female terminals 1 & 2, until clear bubble free air is seen
ensure fluid is topped up continuously so as not to run pump dry
individually bleed each wheel in sequence: RHR, LHF, LHR, RHF.
top resevoir to back up to maximum

If, as I suspect, there is no fluid then your pump is broken. What normal happens i is that the two pistons in the pump seize and do not slide in or out = no pump.

This can be fixed quite easily yourself but it does mean removing the ABS modulator & pump.

taters,
wow! thanks for the info. i will try to get around to checking that this weekend, and let you know how it goes.
