paulrenn Posted October 3, 2002 Share Posted October 3, 2002 Hmmm...was nosing around the fuse box (as one does) and noticed the ABS2 fuse was missing. I presume everyone else has this fuse all present and correct? I guess the previous owner wanted to disable the ABS for some reason. But what puzzles the hell out of me, is that ABS1 fuse is still in there. Anyone heard of pulling the ABS fuses before, and which ones, and why...!

FaithStalker Posted October 3, 2002 Share Posted October 3, 2002 i think mine is missing as well, i dont think it should actually be there. although others with more knowledge should chip-in at this point! Quote Link to comment Share on other sites More sharing options...
paulrenn Posted October 5, 2002 Author Share Posted October 5, 2002 Bumping this up, could someone take the trouble and check which ABS fuses are present in their main fuse box (engine bay)? Thanks Quote Link to comment Share on other sites More sharing options...
Steve W Posted October 6, 2002 Share Posted October 6, 2002 Sorry Paul, I've had a UK Handbook all this time and couldn't be ARSED to pick it up and look ! ! (I DO apologise ! !). If you're still worried....this is the diagrams in the book: (next 2 replies = 2 photos) Interestingly, on advice from others on here, I've tried pulling the TRAC fuse (No.24 on pic) to try disabling the traction to see what it was like......made NO difference at all ! ? ! (except the TRAC light staying on/blinking at me !) NOW it appears that ABS No. 2 and 1 (No.40 and44? ?) MAY have something to do with the Traction Control ? ? [unless it's more like the actual POWER supply to the TRAC and fuse 24 is the operating one ? ?] Fat S. Quote Link to comment Share on other sites More sharing options...

Steve W Posted October 6, 2002 Share Posted October 6, 2002 I'll pop outside in a minute (if I can be ARSED !?) and see if mine's got ABS 1 and/or/ ABS 2 in there....... Fat S. Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted October 6, 2002 Share Posted October 6, 2002 Fuse no. 45... Diff cooler!?!?!?! - Obviously only applicable to UK cars but why would a diff cooler require power??? Quote Link to comment Share on other sites More sharing options...
Steve W Posted October 6, 2002 Share Posted October 6, 2002 From what others have said on here, I gather that the UK one has a Diff' Cooler ? ? (Jap' Spec hasn't ? ?) Is the Pump for it an electric one, or, mechanical ? ? I would suspect electric ! ! = fuse ? Fat S. Quote Link to comment Share on other sites More sharing options...

Steve W Posted October 6, 2002 Share Posted October 6, 2002 Just got off my ARSE and had a look under bonnet.... I DO have ABS 1 and ABS 2 still in place (?!). The ones which are absent (by the manual) are 30 - HEADLIGHT, High Beam, R/H 31 - HEADLIGHT, High Beam, L/H 32 - HEADLIGHT, beam level control system Well, as us TRUE ricey-boys haven't got auto h'light leveling I wasn't expecting 32, but, why haven't I got seperate High/Low beam fuses ? ? It must be right 'cos on the underside of the fuse cover the 2 H-L fuses (28 + 29) are just called HeadLamp R/H and HeadLamp L/H so Jap'spec doesn't seperate - UK does ? (safety law ? ?) STRANGE. NOW, I want to know about these ABS fuses............. ? Anyone know which does what (can't go exactly by what manual says !) Fat S. Quote Link to comment Share on other sites More sharing options...
paulrenn Posted October 6, 2002 Author Share Posted October 6, 2002 Hi Steve Many, many thanks for the info. So looks like ABS2 is something to do with the traction control system. Wierd! Because I know my trac is definitely still enabled. I tried doing some donuts on gravel and it soon interfered with proceedings! Perhaps there are two fuses that need to be pulled to deactivate it...maybe 40 and 44? But then, don't want to lose ABS completely. Very annoying. I guess I should just get a new fuse and get ABS2 back online. Quote Link to comment Share on other sites More sharing options...

Steve W Posted October 6, 2002 Share Posted October 6, 2002 ? ? Sorry Paul, we need someone who REALLY knows why/what the THREE Traction Control System fuses each do ! ! Your right....can't pull all THREE if it's gonna affect ABS too ! (well, you could, but.....) Matt says he fitted one of the TRAC butterfly removers - (think Phil did/has as well) So the TRAC thinks it's still working but it doesn't shut the throttle......mmmm......maybe. [ I WOULD like to be able to turn the TRAC right off, but still have ABS, AND, not have the TRAC light blinking ! ! ] ANYONE ? ? Fat S.

paulrenn Posted October 6, 2002 Author Share Posted October 6, 2002 Time to check mkiv.com I suppose. LOL @ paint preservation Quote Link to comment Share on other sites More sharing options...
paulrenn Posted October 6, 2002 Author Share Posted October 6, 2002 Well, found this page on there. Just says pull "a 7.5 amp fuse" but which one!!! Or, seems like we can pull connector from the trac system itself, but I bet that lights up the TC lamp? Quote Link to comment Share on other sites More sharing options...

Steve W Posted October 6, 2002 Share Posted October 6, 2002 Yeah, that's No.24..... That's the one I pulled..... made the light blink.... Didn't really give it a good hard welly-ing but still didn't seem to want to spin ? ? Fat S. Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted October 6, 2002 Share Posted October 6, 2002 If you unplug the trac motor or pull the fuse, it will disable the TC and make the warning lights flash. Also, if you have an auto, it'll make the gearshift a lot harsher as the butterfly closes slightly during gearchange. It's noticeable under hard acceleration - Drag racing etc. Steve, in the dry, you'd be hard pushed to get the Supra to wheelspin from standstill - Try again in the wet Quote Link to comment Share on other sites More sharing options...
SimonB Posted October 7, 2002 Share Posted October 7, 2002 I finally got fed up with mine flashing and took the bulb out. Dunno if it's the same on a pre-facelift car, but on mine you just take off the top bit of dash, unscrew the bit where the warning light is and twist and remove the bulb. It's a bit like a Christmas tree light... Quote Link to comment Share on other sites More sharing options...
Ian C Posted October 7, 2002 Share Posted October 7, 2002 Can I suggest that the UK/US/NATO spec Supras have the traction control system that uses the rear brakes as well as the throttle butterfly bitchslap system, and the rear brakes would be powered for TC purposes by the ABS system. This would probably be as seperate a system as possible to ensure ABS worked even if TC was switched off or failed in some way. So, there would be a fuse and a relay for this part of the TC system but it uses the ABS system, therefore the labelling is ABS. Sound OK? I know in the small relay box on the turbo side of the engine only has three relays in it, the fourth being marked as ABS as well. Mine being a j-spec, this is understandable as it doesn't have the braking component of the TC system. -Ian Quote Link to comment Share on other sites More sharing options...

It is my understanding that the system is almost entirely seperate from the normal braking system bar use of the brake fluid tank. I guess that's why it is so easy to get rid of the TRAC, just pull the fuse which disables the TRAC ECU and pump. I should be having my TRAC pump and ECU removed in the next month or so.

Frank Posted October 7, 2002 Share Posted October 7, 2002 Paul, I noticed that I had no ABS 2 fuse but when I looked at where the fuse would locate there were no metal contacts at ABS 2 in the fuse box. My car is a Jap 1997 TT manual with UK spec Brakes and the ABS is working ok. Hope this is some help. Regards Frank. Quote Link to comment Share on other sites More sharing options...
