No power from OBD !

[hghareeb]

Hi,

just got my nanocom. yesterday it works just as it should be in my pc but it seem my socket in my td5 defender has no power ! It was located out side the cabin just below the cubby box so i tried to clean it but no luck .
I also checked the fuses no 8 and no 5 ( engin box) its just fine ! . The socket has 5 wires i believe the purple should have 12 volt but mine has no power . So i tried to hot wire it from fuse no. 8 and it works but it seems it doesnt interact with ECU and it couldnt read the fault or any other !!

any advise

Does your internal light work? its on the same fuse

Any thoghts !!

Check for Chafed loom back to the ECU then the ECU plugs and Earth points.

Well i believe the only remaining thing to do is to trace the black loom that goes out of the ECU to somewhere , the obd socket is out of this cable but it seem its very hard to trace it and i can see no thing wrong with it from outside .

To be honest I dont really understand your post

Are you saying the OBD plug has been relocated ?
Do you have a copy of RAVE with a wiring diagram?

The wiring of the diagnostic socket is not complicated so it should be relatively easy to fix

If you dont have a wiring diagram I might be able to email you one

Thank "djam1" for trying hard to understand my weak english .

yes the socket was relocated for some reason outside the cabin, i already had a look at the RAV CD accordingly i found that the purple wire in the socket should have 12vlt. power while mine has no power .

the wires should be disconnected in the middle between the fuse box and the socket !! I ended up today to hotwire it from the fuse box to the socket and try to connect my friend ( Autologic) diag. Device and see if it read or not .

thank yoy for your help.
