Diagnostics socket????

[supadik]

Hello again, does anybody know if a 95 4.0ltr chim has a diagnostics socket? If it does where is it and does any body know the pin assignments?

Cheers

Yes there will be a diagnostic socket floating about on part of the loom associated with the relay panel above the battery in the passenger foot well. I f you haven't already located the battery, remove the carpet panel which is at the deepest point in the passenger foot well - it's not fixed in place other than by friction. If it's the same as my '94 model then you should find two conectors - they are both for diagnostics - one connects to a simple fault reader and the other connects to a more sophisticated diagnostic unit.

If you have a suitable fault reader then you shouldn't need to know the pinout. I'm pretty sure that the protocol isn't ODB but could be wrong.

Got me confused there, the Lucas 14cux, only has one 4 pin diagnostic socket, and its a serial data pin connector, with a unique coding. No way OBD complient, so you need the correct reader. I cant pass comment on the latter Lucas Sagen units or indeed if these where ever fitted by TVR.

Hi. Do you know the location of the socket, it's colour and dare I ask the wire colours or am I being too hopeful

It's black and square and is part of the trailing loom in the passenger footwell.

Mark: no, TVR never switched to the GEMS system.
