Bet you don't know the answer to this

If anyone can answer this question I'll be well impressed. I'm actually quite impressed with myself for asking it in the first place.
No 50:50/phone a friend/ask the audience/coughing.
On the ECU diagnostic plug there are 3 pins. The plug is a standard rover one. I presume 1 is +12v, 1 is signal ground. Is the last pin J1850+, J1050-, K-line or L-line?
Cheers,
Richard

It is a three wire serial interface which is proprietary to the Rover fault code reader.
I believe that they are gnd, TX and RX but don't hold your breath!
Why do you want to know? Trying to build your own fault code reader?

Not quite - though I wish TVR had included the LED fault code display fitted to USA exported RR. It really would be very useful to be able to see if a code is being indicated as they are quite informative.
Presently my 99 Chim 4.0l is poorly at the menders. She failed the MOT emissions test due to a missfire which has been intermittently present for a few months. The independent dealer (no names) seems to be having difficulty sorting this problem out, having put her on the 'star tester' which didn't find a problem.
In my car I have a sat nav system which has an OBD II add on module. This can interface with the ECU via an OBD socket and report fault codes. I've just bought this module as I intend to keep my sat nav and install it in my cars in the future. I was interested to know if I could use it for the Chim.

The connection details are in the bible 2 along with the codes and potential causes but in my experience they are not brilliant. You can get a plug in reader but is not that clever. It can lead to replace the injection system by stealth because of too much reliance on it.
The RR NA system you refer to uses the GEMS ECU which is not the same version as the one used in the TVRs so they are not compatible as far as I can tell.
I did look into this but came to the conclusion that hooking into a professional system gave far more information and help than knowing that a particular code had been reported.
