98 3.9 OBD II?

(1/3) > >>

skip:
I picked up my disco yesterday and so far so good, however I have already had a couple of backfires on gas. I'd like to check that the AFM hasn't been killed so I was wondering if the dico is OBD II or not and if so where the connector is?

A friend of mine has a reader so it'll give me a good chance to see what it's all about.

Thanks Skip.

OBDII is an industry standard thing isn't it?

Skippy:
Not on a Lucas hotwire injected Disco it isnt!  You can get some basic srror codes from the Hotwire system but not really that much, and im not sure that it's OBD compliant?  The "Thor generation had OBD 2 prior to2001 when it became std in the UK, but that was only because it was sold in the US where it was allredy std.

Thanks so far, what do I need to retrive fault codes and the like from this beastie?

BTW I now know why everyone raves about the V8, ooooooooooohhhh! it's nice :lol:

Range Rover Blues:
Sorry I got mixed up, if it's 14CUX/Lucas hot wire than you need testbook or Rovacom.  Shame you are so far away.

To clear the faults you can disconnect the battery for a few minutes.  To diagnose them you need a garage.

Rovacom beats test book into the ground here, you can watch all the signal inputs and outputs on the screen real-time.
