Steviegeeza Posted April 11, 2006 Share Posted April 11, 2006 1993.5 Jap Supra MKIV TT auto 90K miles. The overdrive off indicator occasionally flashes 1 in 4 seconds after the car has been going quick! The box is working fine - smooth changes at the right time (best auto I've ever driven). I assume this must be the auto ECU trying to tell me somthing - Anyone know what it is ? Thanks Steve Quote Link to comment Share on other sites More sharing options...
Steviegeeza Posted April 11, 2006 Author Share Posted April 11, 2006 Should have searched first Poor quality speed signal convertor causes the flashing OD off light, and I have seen the flashing spoiler light, another symptom. Who's convertor delimiter is deemed to be best by this illustrious group? Steve Quote Link to comment Share on other sites More sharing options...

veilsideTT Posted April 11, 2006 Share Posted April 11, 2006 Mine does this too. Apparently it can be the connections inside your odometer. Pete at thor recommended soldering a wire onto the speed sensor signal (going into the unit) onto the speed sensor wire (going out of the unit). Creating a bypass if you get me Supposidly thats were the signal breaks down and causes the O/D light to flash (code 42 usually - speed sensor) HTH Quote Link to comment Share on other sites More sharing options...
jamesmark Posted April 11, 2006 Share Posted April 11, 2006 ok i have found what is at home on here mines was fault code 89, when my o/d and slip button flashed hope this helps Quote Link to comment Share on other sites More sharing options...

veilsideTT Posted April 11, 2006 Share Posted April 11, 2006 When it says "connect the pink to the blue/red wire" does that mean literally cut and disconect the pink wire from the unit and connect it to the blue/red? or just splice the pink wire onto the blue/red leaving the pink still attached to the connector also?
