greeksuprakent Posted July 26, 2010 Share Posted July 26, 2010 Helo Guys, Just bought my Supra yesterday ... has one problem which I want to sort out first... when it is driven "hard" on a round about... or about 100mph (there is a wheel vibration since I need some tracking) ... the Master light and Interior light come on flashing randomly but always together never first one and the other ... they both come on simultanesly. I am sure it is some sort of sort circuiting... but where will I find it and cure it. My supra does not have a front splitter so the master light cannot be coming from that... (I dont even have the switch for the front splitter on the dashboard so I dont think it was ever fitted.) Cheers Vasilis. Link to comment Share on other sites More sharing options...
Smallshinyant Posted July 26, 2010 Share Posted July 26, 2010 Sounds like its the switch that notices if the door is closed or not. When you are parked up, you should notice that when the door is open the interior light is on and a warning light. Check if its the same ones your getting at speed, if so check the switch around the doors. Link to comment Share on other sites More sharing options...
greeksuprakent Posted July 26, 2010 Author Share Posted July 26, 2010 Yeap it is the door switch of the passenger... nothing to worry about there :-) the door needs adjusting anyway :-) Link to comment Share on other sites More sharing options...
neo2810 Posted July 26, 2010 Share Posted July 26, 2010 Get your wheels balanced before your tracking and see if that fixes the vibration. I have the same problem and it's balancing but my car is in on Sat for a full tracking geo anyway so it will get sorted there. Link to comment Share on other sites More sharing options...
