Fault code pulling - 1988 5000 TQ

[Denis]

  Very easy

  check http://www.sjmautotechnik.com/trouble_shooting/100ecuf.html

  I just did on my 100Q , 200T.

  Start the car , warm it.
  Plug the jumper (or a switch wired to it as i did+ led) for more than 4sec, say 5.
  The CEL (Check engine light) ll bright 2.5 secondes to show it ll show the fault code.

  Then will flash the four digit code.

  ex: 2311 ll display as; 

  O  O             O O O             O             O O .......   then a 2.5 sec bright to do again the fault code display...

  its coolant temp sensor.

    Does anyone know which terminals you would use for the LED indicator when pulling codes. My check engine light appears to be burned out. I have a check box I've built, and want to use it. Also, can anyone verify that the two terminals on the top of the FP relay triggers the sequence.
