Kaamos Posted January 11, 2012 Share Posted January 11, 2012 Everything's pretty much in the title..... My OD/Off light has always been flashing from time to time, rather rarely, since I bought the car... but for the last week it has been flashing almost constantly every 1 and a half second or so..... Any clue of what this could mean ? Quote Link to comment Share on other sites More sharing options...
David P Posted January 11, 2012 Share Posted January 11, 2012 (edited) It's telling you there's an electrical fault, pin the diagnostic port and read the fault code. Then fix the fault.

SPG Posted January 11, 2012 Share Posted January 11, 2012 Do you have an Aftermarket ECU, as my light does the same thing with my MINES fitted and no fault codes Quote Link to comment Share on other sites More sharing options...
Gabriella Posted January 11, 2012 Share Posted January 11, 2012 That's a code 42 speed sensor issue. The car has probably been delimited badly rather than buying a Thor delimiter. Not a lot to worry about. Quote Link to comment Share on other sites More sharing options...
Kaamos Posted January 12, 2012 Author Share Posted January 12, 2012 David P, thanks, but I forgot to mention that both diagnostic ports are mute SPG-26, thanks for the hint but no Karolina : this would explain why, from time to time, cruise control doesn't work and active spoiler behaves weirdly (unfolds at 10mph and stays inside doing 80) Quote Link to comment Share on other sites More sharing options...
Robzki Posted January 12, 2012 Share Posted January 12, 2012 This is usually connected(excuse the pun) to the buffer in the odometer can't remember the wire colours(blue/pink?) but usually the dry solder joint in the odometer can be bypassed and solves the issue. From memory the speed sensor sends its signal via the odometer for some reason then on to the ecu. It then causes issues as you describe Mine did the same when I got it and this sorted it. was intermittent, If it was down to a thor delimiter I'd assume it would be constant R.

ronttuk Posted January 12, 2012 Share Posted January 12, 2012 does this apply to uk spec (except the delimiter of course) Quote Link to comment Share on other sites More sharing options...
Guigsy Posted January 12, 2012 Share Posted January 12, 2012 My of light and trc light flash on my uk. It's intermittent and I can't notice anything wrong. Various garages it's been to also can't work it out. But on a jspec it's usualy speed limited but you need to check the codes to be sure as could be something else Quote Link to comment Share on other sites More sharing options...
Kaamos Posted January 12, 2012 Author Share Posted January 12, 2012 Mine is an UK-spec and beside the cruise-control and active spoiler I didn't notice anything wrong so far, except it has been rarely intermittent for 2.5 years and now for 2012 it became constant Robzki, thanks for these details.

ronttuk Posted January 12, 2012 Share Posted January 12, 2012 my uk does it till it has a 30 min run then it stops im wondering if its condensation on the connectors when it warm its fine until it stops flashing the cruise wont work though Quote Link to comment Share on other sites More sharing options...
jim Posted January 12, 2012 Share Posted January 12, 2012 I thought it was supposed to flash depending on your speed, ie it'll flash to 'recommend' that you turn the O/D off if you're driving in heavy traffic for example. Quote Link to comment Share on other sites More sharing options...

The Raven Posted January 12, 2012 Share Posted January 12, 2012 My uk spec did this, but also went into limp home mode, TPS was the issue Quote Link to comment Share on other sites More sharing options...
David P Posted January 12, 2012 Share Posted January 12, 2012 Edit: It's telling you there's an electrical fault, un-'mute' a diagnostic port then pin it and read the fault code. Fix the fault. Quote Link to comment Share on other sites More sharing options...
Kaamos Posted January 12, 2012 Author Share Posted January 12, 2012 Edit: un-'mute' a diagnostic port then pin it and read the fault code. Fix the fault. I went to a couple of toyota garages a while ago, they couldn't "un-mute" the diagnostic ports for they didn't have the elecrical diagrams for the supra, so this was never sorted out....

Hi, bit of a thread Hijack but can you add your UK spec to the UK spec register. It's in the members section or you can follow the link in my signature below. Thanks Quote Link to comment Share on other sites More sharing options...
Kaamos Posted January 12, 2012 Author Share Posted January 12, 2012 (edited) you add your UK spec to the UK spec register. PM'ed The Raven : thanks, I'll be looking for this guide Edited January 12, 2012 by Kaamos (see edit history) Quote Link to comment Share on other sites More sharing options...

Shane Posted January 13, 2012 Share Posted January 13, 2012 (edited) 2 out of the 3 mkiv supras I have owned have had this fault and both were down to the buffer circuit in the odo as previously mentioned. On both of mine there was no fault code stored. Search for pink wire odo or something like that. Its a 5 minute job and worth doing if only to eliminate it from the equation .

Kaamos Posted January 18, 2012 Author Share Posted January 18, 2012 Thanks for the link David P, sounds much useful ! 2 out of the 3 mkiv supras I have owned have had this fault and both were down to the buffer circuit in the odo as previously mentioned. On both of mine there was no fault code stored. Search for pink wire odo or something like that. Its a 5 minute job and worth doing if only to eliminate it from the equation . I'm not quite sure what to do with this wire but thanks for sorting the pink one from the blue one Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 18, 2012 Share Posted January 18, 2012 You first need to get the diagnostic ports working. You need a wiring diagram and an auto electrician. Wiring diagrams are in the proper shop manuals, these are downloadable I believe. I bought factory paper ones. Quote Link to comment Share on other sites More sharing options...
