Ok, many thanks, I’ve run the unlock software a few times and cleared faults but it comes up with the same every time so I’ll ignore that as you say it may be bogus. What can be done about the alarm sounder? Sorry, I have no idea what, where it is and if I can simply isolate without causing...

Do you recon that’s what’s blowing the fuse? How do I clear those faults? They would have been there for years, then I can run it again and see what the current faults are.

Well, cleaned C104 and C204, spliced in new OBD changed fuse 44, that set the alarm off and blew the fuse. I’m guessing like my first post on this thread. Anyway I thought I’d try and run the software expecting it to be in the same condition with no Rx values, to my surprise it ran as should...

I’ll post results darthdude but I’m down another rabbit hole at the mo...... by the way, OBD wasn’t corroded. Check my previous post where I con checked it after I cut it off. Perhaps the reason the fuse blew is the other corroded connectors. See my response to pwood999 for explanation. Thanks...

Many thanks, I’ll find those connectors and check for corrosion. In the meantime I found fuse 44 blown, air suspension. Perhaps if I’d checked fuse 44 before I cut the OBD connector off?

Hi there! In answer to the timer question there has been no work on the vehicle on that system in the 6 years I’ve had it. Pic of back side of connector attached. I took the vehicle to a shooting buddy of mine who runs a garage and is an ex LR tech. I got him to connect his diagnostic to the...

Grrr, that’s over my head.... OBD connector and relays?

Wet will be contact cleaner that hasn’t dried, the nick looks worse than it is but I’ll have a closer look.

Popped the panel down and got a look at the back of the OBD socket, looks ok, no corrosion as far as I can see. I’m thinking what’s next after I change the OBD socket and there’s still no return signal? I guess I’ll cross that bridge tomorrow......

That looks like a better idea, the one I’ve got coming today/tomorrow has 16 flying wires that I’ll need to solder and shrink sleeve or put bullet connectors on. That’s a week away time I order it and get it. What to do ........

Nope, haven’t got to it yet, tomorrow I hope.

A quick update, I plugged into a mates P38 and the software ran as expected. Rx and Tx values running in both columns so lead is good and the OBD port on my vehicle is duff with corrosion. I’ll try and clean with rat tail and abrasive paper then if still no Rx signal change the OBD socket...

Yep

Did that and still getting ads, perhaps my member isn’t full enough......

I’m in! Small price to pay for a billion years of experience........

Thanks, I’ll give it a go before I cut the OBD2 off and fit a new one. A question, if I perform step 5 now and get the same numbers do I need to go through step 1 to 5 then 6?

Amazon prime, it’ll be here Friday ready for Saturday. Hope there’s enough slack on the harness........

cheers

Yep, that’s what I thought. There are a couple of crossheads that look to be holding it in but they just spin so I’ll need to prize them out at the weekend. I’ll let you know how I get on over the weekend. Let’s hope it’s not the cable from p38spares. Thanks gents.
