fastnfurious Posted September 22, 2011 Share Posted September 22, 2011 (edited) is this normal? i read articles about O/D light flashing after removing the TRAC fuse but not the MANU light, which is kinda weird really... any advise? thanks! btw, i've not been driving the car for almost 8 months now. only warming it up every alternate days for 15-30mins (with aircond and ICE running) to keep the electrical and mechanical parts moving.

Robbie Posted September 22, 2011 Share Posted September 22, 2011 (edited) HI, unfortunately the flashing is normal when you remove the trac fuse. I can't recall th other flashing though. Have you tried pressing the manu button on and off a few times to see if it goes off Edited September 22, 2011 by Robbie (see edit history) Quote Link to comment Share on other sites More sharing options...
fastnfurious Posted September 22, 2011 Author Share Posted September 22, 2011 i think after removing the TRAC fuse, the MANU function won't work anymore thus pressing this button won't toggle the MANU light ON/OFF. the MANU light only flashed once in a while and seems gone now... this is really weird and hope it's not a symptom that my sweet auto box dying anytime soon...

Chris Wilson Posted September 24, 2011 Share Posted September 24, 2011 Starting it every other day from cold is a very bad idea, I would just disconnect the battery and leave it until you want to use it again, even if it's over a year.

fastnfurious Posted September 25, 2011 Author Share Posted September 25, 2011 hi Chris, how come you said it's a very bad idea to warm up the car every other day? i thought it's better for the electrical and mechanical parts? please advise, thanks!

Chris Wilson Posted September 25, 2011 Share Posted September 25, 2011 Plagiarised, as time is short (pub day, today ) It's true, 80 to 90 percent of your engine's life is consumed by cold and dry start ups. Engines usually shut down hot, at which point the oil is thin and drips away from the bearing and other "friction intense" areas. Gradually the oil cools, thickens and becomes difficult to pump. When starting an engine, the lubrication process involves filling all oil galleys, filling the filter, pressurizing the rod, main and cam bearing as well as the entire valve train (filling the lifters and lubricating the cam lobe and rocker arms). Unfortunately, your engine is running while this lubricating process and is meshing metal against metal, hence massive engine wear takes place. Studies have been done by the Society of Automotive Engineers concerning engine wear and engine failures due to the lack of oil and oil pressure during cold start. (S.A.E. Technical Papers # 780370, 3790729, #790751, #821204, #821206 and #821247). From these, and other S.A.E. studies, it has been determined that up to 80% of entire engine wear occurs during cold start ups. A recent test by McDonnel Douglas of Long Beach indicated that up to 90% of all engine wear takes place during the "oil starvation' period of the cold start (New York Times Syndicated Release 5-6-85).

fastnfurious Posted September 25, 2011 Author Share Posted September 25, 2011 won't the electrical parts (say, electronic boards and switches) failed if not been active for a long time? likewise, the mechanical parts too... btw Chris, any idea why the MANU light flashes once in a while (only showing up this week but it's gone now) after removing the TRAC fuse (2 years ago)?

Chris Wilson Posted September 25, 2011 Share Posted September 25, 2011 No, of course not, why should they? Often the cause of TRAC and Manu lights flashing is a faulty speedo converter installation, or the throttle pots being set up wrongly, The latter is a job for someone with patience, that's preferably done it before. What happens if you put the fuse back? Quote Link to comment Share on other sites More sharing options...
fastnfurious Posted September 25, 2011 Author Share Posted September 25, 2011 oh... never done any speedo converter installation before neither throttle pots setup, only removed the TRAC fuse as shown in this forum to bypass the clumsy TRAC function (was informed the TRC light will stay on and O/D light will be flashing - this is normal but not the MANU light which shouldn't be flashing) Quote Link to comment Share on other sites More sharing options...
Guigsy Posted September 25, 2011 Share Posted September 25, 2011 (edited) What I think chris is trying to say is warm your oil before you start the car. Just like the f1 boys do. I don't follow this chris. Everyone starts the car from cold. It's unavoidable. I must have got the wrong end of the stick. For what it's worth on the trac/Manu issue. My uk spec has done this since I got it. Sometimes trc is on and Manu flashing. Other time they are both off. Sometimes it doesn't happen for ages then all of a sudden it happens all the time. Sometimes I can switch the car off and start it again and it's gone. Or the reverse. Sometimes it takes 3/4 times doing this before it goes. Sometimes it just doesn't go. Car drives the same. Manu mode just doesn't operate. Doesn't stop you selecting the gears manually tho. I can't remember if trac control works or not. Iv mentioned this to 3 separate garages (supra specalists) and none of them managed to fix it or have a clue what it could be. Mine is a uk spec so doesn't have a speed converter. So it's not that.

Chris Wilson Posted September 25, 2011 Share Posted September 25, 2011 What I was saying is there is no good reason to to start it every other day. If it is in storage, then once every six months or more is fine. In ny personal opinion. Loads of cold starts for no good reaon - loads of excessive wear for no good reason!

fastnfurious Posted September 26, 2011 Author Share Posted September 26, 2011 thanks for the info guys, it's much appreciated. in this case, will just leave the MANU light flashing since it won't do any harm i suppose. will warm-up the car everyday instead of every alternate day, good advise Chris and cheers~ Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 26, 2011 Share Posted September 26, 2011 Errr, no, I meant don't start it until you next need to use it, even if it's a year away from now Quote Link to comment Share on other sites More sharing options...
fastnfurious Posted December 26, 2011 Author Share Posted December 26, 2011 what i did today... put back the TRAC fuse and the O/D flashing light and TRC light are back to normal now. however, the MANU light is on now and when shifting into R, N, D, 2 or L - both 2 and L lights stay on! what could be the problem now? also notice some kinda air/vacuum noise coming from the undercarriage after putting back the TRAC fuse and when i put the gear into D. is this normal?

bigbloodyturbo Posted December 26, 2011 Share Posted December 26, 2011 why did you remove the trac fuse in the first place? Quote Link to comment Share on other sites More sharing options...
fastnfurious Posted December 26, 2011 Author Share Posted December 26, 2011 many in the forum have removed the TRAC fuse to remove the speed limiter and disable the annoying traction control but in exchange, this will cause the O/D light to flash and TRC light to stay on all the time.

To remove the speed limiter fit the proper piece of kit to do it. When you pull the trac fuse i'm almost sure you stop the autobox from pulling timing during gearchanges to protect itself. I seem to remember some people on supraforums doing this to get harder/quicker shifts and whatnot and ending up with gearbox issues, was years ago when i read it mind.
