OBD-II on the Pajero

Howdy

Has anyone had any experience with using scantool software available on the net to get info from their Pajero?

Specifically, my Paj is a 2000 NM, and the information out there says that it should be ODB-II ISO compliant, but i can't get the car to talk to my pc.

I've know the dealers use their computer to hook up to it, and the Auto trans guy I took the car to was able to use a scan tool from SnapOn, and was able to get lots of lovely live data from the transmission, as well as the engine.

So I know it's there, but in what language?!

Regards, Paul.

Don't you have to use a scantool for the OBD 11 terminal ??
Do you have the correct lead to hook up to your laptop ?
I had a problem with my Verada recently that a generic scantool couldn't diagnose. When Mitsu had a look at it their scantool couldn't reveal anything either. It ended up being the crank angle sensor which they said their scantool didn't pick up and they had to use a specific tester.
I tried getting the imfo out of the dude and from what I could gather they hooked in a laptop and using a specific Mitsu software programme managed to find the problem.
I'm not sure if it's a secret Mitsu site with a password for techs only ??
I do know they can download ECU software patches from some secret internet site.
You do know you can pull any fault codes out of your ECU with a multi-meter ?
The problem with the OBD 11 is being generic there are hundreds of potential fault codes and they may not all relate to your specific vehicle (as I found out the hard way)...................

:rofl: A few years ago my grandfather had exactly the same problem, with exactly the same symptoms, on his VL Commodore - but intermittently. He was trying to diagnose the problem himself (mechanic all his life) and eventually had to admit defeat and take it to a dealer - they diagnosed and fixed it quickly.

I figured there was no way your problem was so simple, so I didn't bother posting. :shock:

Sorry Frank. :oops:

Ta for the reply.
The "scantool" and the "correct lead" is what I'm trying to emulate. For less than $100, you can do the same thing as the $1000+++ tools the dealers use.

I just need to pull my finger out and go back to the auto dude. His $$$$++ scantool did everything except fix the car, so I just need to look a bit closer.

I'm not so much wanting to fix a particular fault, but rather want access to the live data available.

It @#$%s me that the only "happy engine" guage that you get is a temperature guage that sits at the same point whether or not you're towing, cruising, stuck in traffic, melting, speeding, hillclimbing, etc.

You can get economy, power, pressures, temperatures (that vary...) fuel trims, and all sorts from the ECU, all available to be put on a display of my liking.

More research to be done, just not enough hours in the day...

I suspect CAN (newer communication protocol) capable scanner tool is required. I've looked at the connector on my recently acquired Montero LS (GL in AU?) and it looks like a crossover between ISO and CAN (has pin #7 for ISO but also got pin 14 required for CAN although pin #6 is missiong at the same time) :bad-words:
You can learn about connector here:

These are two quotes I never wanna see in the same thread again - disgusting!! :shock:

So - did your grandfather end up getting his "crank angle" fixed :D
