flashing O/D light???

Hi all.

 

For a while now my O/D light starts to flash now and again for a few minutes.

It can go a couple of days without doing it and then it will just start up for no reason.

 

I know it does this if you pull the Trac fuse. But i know i havent ever pulled my Trac Fuse (Not sure i should be admitting that!!) and my ecu has been reset too.

 

My Overdrive still works fine but ive always had a bit of a problem with my cruise controll. I can imagine the two problems are related. Someone suggested in a previous post that it was a speed sensor problem??? (Search button used thank you) ive had a full auto box rebuild and it did it before and still does it now.

 

Aparantly i can pull the codes somehow to see what the problem is. Does anyone know how i do this? or is it done through the diagnositics port? I have the workshop manual, is it in there?

 

Thanks

Scott

De-limiter is favourite....

 

I've got a used HKS SLD for sale.....specific to the auto Supra.

 

Can also recommend the TRL dsc.....this is a combined de-limiter speedo converter

Yes UK i am!

I also have no active spoiler.

Done the TRL mod to stop the Spoiler light flashing!

 

No1 speed sensor is on the gearbox output transmision shaft isnt it?

Worth changing it or not??

I like my cruise controll you see and this problem is stopping it from working some of the time.

I've NEVER found a failed speedo sensor.

 

It's either been a converter problem on the JDM cars or else the odometer output drive has failed. (Either solder joint or just plain failed)

 

If the odometer output has failed then my DSC can repair this.

 

Regards

Ive seen a few people on the supraforums had this problem and it was down to the odometer not sending the signal back out.

 

Aparently bad connections in side the odometer!

One person resolved this by connecting a peice of wire from the input to the output wire thus still leaving the original wiring into the odometer but also making sure the output was getting through.

I'm sure someone posted similar problem.... they resolved it by re-soldering some connections behind odo meter.

 

yep that'll be right. I've just removed my ODO cluster and right-hand warning light cluster and after 5 mins of driving my O/D light flashes. Car still seems fine though.

I'm in the middle of a Thor TSD install while trying to sort a code 42 error that's causing light steering and I'm sure active spoiler issues. I'm wondering if my odometer output drive is bad.

 

How could I tell Pete? How do I know which solder joints to check? Hopefully the TSD install fixes that problem. Check your e-mail Pete, I sent you some questions about the install.

 

Here is a picture of my odometer. Note the lower left corner of the display. Looks like something might have burned up.
