grumps2JZ Posted July 23, 2012 Share Posted July 23, 2012 i took a drive over the hills the other night (quite spirited driving) about halfway through i notcied my overdrive light was flashing i proceeded to drive quietly home with the light still flashing... the next morning when i drove to work the light was no longer flashing and everything seemed fine. any ideas what was the cause of this? is it a temperature warning perhaps? or warning of iminent disaster comming my way?

stevie_b Posted July 23, 2012 Share Posted July 23, 2012 Possibly a code 42 error. These can happen once several conditions are met, two of which are: 1) coolant is up to temperature 2) travelling at over 45mph ish. Get the error codes from the ECU using the paperclip trick.

grumps2JZ Posted July 23, 2012 Author Share Posted July 23, 2012 battery has since been disconected for about 5 minutes, will this have wiped any stored fault codes? Link to comment Share on other sites More sharing options...
stevie_b Posted July 23, 2012 Share Posted July 23, 2012 Yes it will have, you'd need to drive around until the o/d flashing happens again and then try the error codes. Link to comment Share on other sites More sharing options...
