I own an Isuzu MU 3 litre turbo diesel of 1999 manufacture and I have a problem concerning the ABS system.

For 12 months or more I have had the ABS fault light permanently on whilst I drive.
2 days ago I found a garage here in southern Russia which has the computer programme for my vehicle.

They checked out, amongst other things, my ABS fault.

They cleaned all the wheel sensors but told me that a relay in the ABS brake fluid system requires changing.

The computer programme is in Russian and the computer identified the part as "Relay for pump for brake fluid in ABS system"

The garage is not an Isuzu garage and they could not point to the part that requires changing. I have looked through the .pdf Manual I have for Isuzu [PubNo RV99_02-01.E] which I obtained off the Internet but being a non-mechanic myself I am at a loss to identify the part that requires replacement.

Could anyone help me out and identify "Relay for pump for brake fluid in ABS system"

Many thanks,

Jeff Gordon
