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.
