hi all.
the cap is missing from the end of the test book connector, i have found pictures of the connector but cannot see which terminals are bridged together when the cap is on. it also looks like from the pictures a wire bypasses the loom end of the connector and loops around into the cap end of the plug. can any tell me the lay out of the connector and cap plug . cheers


'97 disco
 
Are you sure the picture represents an actual wire? Maybe it's just a thing to stop the cap getting lost? Many of us drive around with no cap at all on our diagnostic connectors, going commando as it were. If you search on here I think there's some discussion about swiping suitable caps of other cars in scrapyards, but they don't really need one.
 
1. i have recently purchased a fuel injection fault display from e bay usa to suit a 14 cux fuel system in my 97 disco . The info i have via a britsh v8 site Rover 14CUX Hot Wire Mass Flow EFI: Service and Troubleshooting about the 14cux system with this display , to clear the faults on the display the cap has to be removed then reconnected so i either need another way of clearing the fault code or info for the layout of the cap for the plug so i can make one up . does this make sense?

2. also i have followed some info from steve heath engineering site about wiring one these displays in and i think i have wired in into a power supply ( key on feed) that cuts out before it can save any codes , perhaps the unit should have constant power ? any one know?
 
Ah, the V8 I'm not so sure about, not having had one. The diesels are fairly straightforward, you just leave the plug open and plug in a diagnostic device when you need to.
 
FWIW my Disco 2 TD5 doesn't have a cap on the end of the socket. I'm assuming the socket is the one under the dash where the garage plugged his autologic gadget into.?

Are there other diagnostic sockets anywhere else - engine bay etc.?

Sorry for the thread hijack! ;)
