Well after a load of dirty fuel over the weekend I had the Patrol in the local Nissan dealer yesterday. It ended up costing me a tank of diesel and $140 for a new fuel filter and for them to delete the fault code on the engine computer.
My question is if this happened out in the scrub I can change the fuel filter, but is there a simple way I can delete this fault code or reset the computer?
Thanks in advance
Snowy

You think as I do in respect to computer engine management, I guess if your in the
Simpson Desert you just pop over to the nearest Dealer....is there any near the
Lone Gum Tree , That's one of the reasons why I like my old and Basic 94 Troopy, No electronic stuff, No Electric windows though a left side one would be handy,
So is there anyone reading Snowy's post who has had THE experience way Outback
and whats the solution, One buys an Off road vehicle , takes it Off road and the computer craps itself, It would be covered under under Warranty but do they go to the crossing of
Lake Poeppel to fix it.???

Just disconnecting the battery for a while is usually best way - typically 1 hour.

'No reason you cant drive the car with a fault code anyway '
exactly. Does anyone have the early 3.0l
Gregory's manual as it had all the fault codes and probably tells you how to reset them?

Easy. Get the
gregory's manual. Make up a wire link that fits into the connector. Read the codes as per instructions. To erase, just re-insert the link, leave for 2 seconds, and pull out.
In any case, there would be no need to erase the code as such. It does not affect operation in any way.
If the engine
check light came on due to water in the filter, then this does in fact not store a code. The float switch inside the filter is wired in parallel with the output from the ECU to the engine
check light. The ECU does not detect activation of that switch.

Hmmm,
I wouldn't disconnect the battery because then you would need to know and re-enter the security code for the radio for starters.
The Engine Management Computer should be protected by a fuse and this you can pull out, leave for an hour or even overnight, then reinsert.
This will reset the computer back to factory default and not interfere with any other electronic devices in the vehicle.

Disconnecting the battery is the correct Nissan approved way to remove the codes - sometimes it doesn't work because battery is not disconnected long enough - Nissan recommends 24hr but 15 mins is often enough and haven't seen one myself that takes longer then the 1 hr I suggested.

Why wait for that long if you can do it in less than 30 seconds?

Another thing i didnt mention that will throwa spanner in the works for you. If you disconnect the battery long enough, it MAY loose more than the fault codes , some times , ecu programing goes astray and vehicle could end up in limp mode .
So , if the car is running and you get a fault code , just drive it till you get somewere were you can fix it lol . Within reason of the fault code or course

Hi
Rock Crawler
Don't need to guess or worry about unseen things in this situation, thats why its easier ( but not the quickest as Hl suggests ) to just stick with factory reccomendation.

Here's a resetting proceedure for a TD5 Disco;
Stop car turn off ignition
Open drivers door
pull key from ignition
close drivers door
re insert key into ignition
close drivers door
re-start car
Fault should clear (ie) dash light of the fault should go out, in my case the ABS/TC lights on the dash.
I have a faulty rear ABS sensor which i will replace soon, and occasionally i get a light come on in the dash, which i clear with the above proceedure.
BTW, ABS and TC still work even though one sensor is faulty.
If it doesn't go out then no big deal i just get it cleared next time i'm near a dealer, which cost from $25 to $45 depending on where you are.
Techknoledgy don't ya just love it ;-))
