Right
ABS does no work
ABS warning light on constantly
the diagnostic box works for everything except the abs socket which is dead so if i is not he relay underneath then if I connect to a replacement pump which is just tied up to the side then if the controller is well stuffed the new one wont be so it will give an error message
do you think it will work ???
going to try i tomorrow.
funnily enough the car brakes beautifully as it is
abs problem - novel solution ?

My ABS light stayed on all the time-one of the reasons it failed the MOT
So to pass MOT I tried several things as I didnt want to have to resort to taking the dial pod apart to remove the bulb
I removed the relay and voila, the light did its trick-a couple of seconds on to say its there, and then it went out-just what the MOT man wanted
So, relay removed...means no ABS right?! Wrong-just for a laugh I slammed on the brakes-ABS kicked in no probs-with no relay!!!!!
Now, someone tell me the 480 isnt full or wierd and wonderful surprises!

Don't know if this is the case for the newer type ABS, but I had this problem with the early type ( '89) with the computer in the boot.
First I cleaned all the sensors, after that I cleaned every connector to the sensors, ABS unit and computer and still had this problem. I gave up and went to Volvo. The mechanic told me that he could try to find the problem not by diagnostics, but by measuring every connection and component one by one. The idea of Volvo working a full day on this without being sure that the problem would be solved made me investigate further myself.
I thought I had cleaned all connections, but then I realised that there is an earth point below the left rear cluster. The same region as the abs computer. Cleaned the earth and problem solved. Seems that if the ABS computer has a bad earth (or power supply, would give the same effect I think) it can not work properly. Maybe something to check. If you have the newer type of ABS with the computer in engine bay you have to find its earth yourself.
