roboldham Posted October 21, 2002 Share Posted October 21, 2002 Hi guys, just joined up - posted this on smartgroups uksupras - but wanted to run it by you folks too: Late '98 MKIV TT VVTi Tiptronic I can't reliably switch off my Slip Control - sometimes when the engine is cold I can - but if I put it back on (default) then I can't switch it off again. When SNOW mode is on for whatever reason, I CAN normally switch it off (but not always). I can always switch on SNOW mode though. This leads me to the verdict that the OFF switch could be at fault (although not likely as it normally works for switching off SNOW mode) or there is some logic or mechanical problem elsewhere. Anyone any more ideas? Thanks - any help appreciated as I like to drive like a man :-) R Quote Link to comment Share on other sites More sharing options...
Syed Shah Posted October 21, 2002 Share Posted October 21, 2002 You could take the fuse out, to turn it off for good. Quote Link to comment Share on other sites More sharing options...
redline Rooster Posted October 22, 2002 Share Posted October 22, 2002 Well I had the SAME PROBLEM on my car!!! - its not as new as yours but what it turned out to be was the "TRC OFF" warning light has a nice little safety feature built in that if the light is not working, it wont let you turn the TC off "for safety reasons" as there is no way to tell you TRC is off until you spin out and hit that nice oak tree over thar!! Basically on my car if i hit the dash board sometimes the TRC would work properly, so i lead me to believe a dry joint was lurking!! - i took the display unit apart ans low and behold there it was the most sh*tty soldering i've even seen! - i ran some new decent solder joints over it put it back in and the TC now works fine and i've had not a bit of trouble in over 3 months! You may just have a blown bulb as you car is so new - but if the soldering is still as crap then it could be a dry joint! P.S - does your red warning light come on too sometimes when you try to switch the TC off?!?! L8R Rooster :flame Dev Quote Link to comment Share on other sites More sharing options...
Terminator Posted October 22, 2002 Share Posted October 22, 2002 Rooster, just curious, but the crap soldering you refer to, is this original or had a previous owner run a muck with a hot iron? Quote Link to comment Share on other sites More sharing options...
roboldham Posted October 22, 2002 Author Share Posted October 22, 2002 WOW someone who doesn't think I am crazy! Thats a good idea - I'll check the joints at the back of the bulb itself (or connector at least) It has worked once or twice - and no I didnt get a warning triangle at any point. But thanks - I'll check it out and let you know! All I have to do now is figure out how to get behind the lighting unit - any bright sparkies out there?

Terminator, Well the soldering was the original!!! - basically the Printed Circuit Boards that hold the lights are "wave Soldered" by machines, this is automatic very cheap and very fast!!!!! - the only thing is if its done too fast the joints dont get thier fair share of solder - then over the years the extreme heat and cold that a dash board encounters in a car eventually weakens and cracks the joints, as it did in my car!! coz on hot days the TC worked fine but cooler days it was totally temporamental! as the jointed expanded and shrunk with temperature!! So i just re soldered them by hand giving each joint a good emount! job done! - toyota wanted £160 for the new light unit!! OUCH!! good job i fixed it myself!!

R roboldham, well its work checking - but seeing as yours is a '98 car i'd be supprised if the joints had gone already! - it will most likely be the bulb as they can just pop just like that even if they're not used much! as for getting behind the dash you just need to take the top cover off, above the clocks, this then exposes the light display units for diagostics and TC OFF light - its about 5 screws thats all, just be carful of the wiring - AND DO NOT TURN THE IGNITION ON WITH WIRES UNPLUGGED!!!! other wise you WILL trip you airbag warning system and you'll have to take it to Toyota for them to reset it!! cool hope that helps mate! good luck!!

NOt quite true, you can reset this with a piece of wire and some dexterity. Quote Link to comment Share on other sites More sharing options...
Branners Posted October 24, 2002 Share Posted October 24, 2002 Originally posted by Martin F NOt quite true, you can reset this with a piece of wire and some dexterity. cool, where can I buy this dexterity you talk of I have the same problem with my UK car, and I know I have dash light problems so it is probably related to that. Basically my heating LEDs mess about and sometimes work and sometimes dont. So its probably more than just a blown bulb or dry joint..must get it checked some time.

Ian C Posted October 24, 2002 Share Posted October 24, 2002 You know on facelift versions, with the trac warning light in that top bit of the dash, are you saying that if you take this bit of dash off and disconnect all the multiplugs, then switch the ignition on, the airbag light will come on and need to be reset? I ask because I have not only had the ignition on with the whole dash off before, but also driven to Halfords and back without the dash on, and never had an airbag warning light issue. Your indicators don't work with the top bit removed, though, I can certainly vouch for that! -Ian Quote Link to comment Share on other sites More sharing options...

JB You've either got it or you haven't. I had that problem with my car as well (intermittant heater lights) and it tuned out to just be the connections to the A\C amplifier box on top of the radio working loose.
