lust2luv Posted February 3, 2005 Share Posted February 3, 2005 Broken abs? Thought you were posting about a painful stomach injury! Stupid question, but are you 100% sure you have ABS? Not all Supes do. Link to comment Share on other sites More sharing options...
s-u-p-r-a Posted February 3, 2005 Author Share Posted February 3, 2005 yeah its got a A.B.S ecu behind the dash and its got a A.B.S relay behind there aswell Link to comment Share on other sites More sharing options...
absz Posted February 3, 2005 Share Posted February 3, 2005 do you have a abs light come on when you switch the ignition ON . i think the abs relays are mounted separate on the offside inner wing inclosed in there own black box. Link to comment Share on other sites More sharing options...
Nic Posted February 3, 2005 Share Posted February 3, 2005 If there is a problem with the ABS it is turned off completely by the ECU and the ABS warning light on the dash will be permanently illuminated. Do your other warning lights work on the dash when you turn on the ignition? Might be worth doing a diagnostic test to see if the ECU has registered an ABS fault.

Ian C Posted February 3, 2005 Share Posted February 3, 2005 I smell a "dodgy car trader removes ABS bulb from dash because it's cheaper than fixing the problem" incident. -Ian Link to comment Share on other sites More sharing options...
s-u-p-r-a Posted February 3, 2005 Author Share Posted February 3, 2005 i know the abs worked when i bought the car a year ago i got the car direct from japan, i took it to toyota to get a full check on the ecu but there dident have the codes so i dont know what i can do Link to comment Share on other sites More sharing options...
TLicense Posted February 3, 2005 Share Posted February 3, 2005 Right, from my experience, and that of quite a few others on this board, the printed circuit board that the bulb mounts onto for the right hand warning lights usually has a *LOT* of dry breaks. Motor companies obviously have to make cars VERY idiot safe, and so if the ABS isn't working in any way the ABS light should come on. It should also come on for a few seconds when you first start the car. Certainly mine didn't and it was because of all the dry breaks in the circuit board mentioned above. I simply 'oiked the board out and with a continuity tester and soldering iron made sure all the connections were good. Now, I have had with my car, on one, and only one occasion, keyed on and the ABS light didn't turn off. I turned her back off and then on again and still it didn't turn off. I stsrted my drive home, and tested the brakes and sure enough no ABS. When I got home, I turned the car off went into the house to find out which fuse the ABS runs through, came back out, turned the car on, and the ABS light had gone off. I've never had a problem since. Anyway so what I'm suggesting is that you first of all check that the light is coming on when you key on. If not check the fuse. If the fuse is good, strip the RH warning panel out and check all the connestion on the circuit board. Once you've done this you should have some indication of when the ABS is working or not. (ie the light should be on all the time if it's not working) Then it's a case of checking the ECU which is behind the stereo if memory serves me right. I would make sure that the plug into the ABS ecu is inserted firmly and the clip is "clicked". If that's all good then I would suggets the next thing is to have a look at the wiring guide on mkiv.com and check there are no breaks in any of the wires. If they're all good then I would suggest you get a 2nd hand ABS ecu and try that, other than that I'm out of ideas. Let us know how you get on, Tony Link to comment Share on other sites More sharing options...
s-u-p-r-a Posted February 3, 2005 Author Share Posted February 3, 2005 cheers mate , have had a few problems with the wiring behind the dash near the warning lights but i thought i had sorted it out cheers for the advice i will have a look tonight and i will keep you posted Link to comment Share on other sites More sharing options...
