I have my trailer hooked up to the Patrol with a 50 Amp Anderson plug which charges the trailer's deep cycle battery. Have done about 20,000 km with this set up - all OK.

Last week, on the way to Googs Track, I noticed the battery was not charging.
Called into a tractor/machinery dealer at Wudinna, looking for an auto electrician (they did not have one). I left the car (4.8 L auto) idling for about 15 - 20 mins while we fiddled around with the trailer Anderson plug, removed & reconnected it many times, cleaned the terminals, etc & generally investigated. Could not get the battery box display to read that it was getting a charge. Gave up.

Then I went to drive away - DISASTER ! Immediately felt loss of power & revs. Could not get over 2000 rpm and it took forever to get to that point. The engine management light became illuminated. Headed to Ceduna in the attempt to solve the issue with a Nissan dealer via their diagnositics unit.

The manual says OK to drive but may notice power loss & increased fuel useage. Sure did! I estimate we were getting 40 L / 100 km at approx 75 kph - max 80 kph. Camped between Wudinna & Ceduna, again removing plug & trying to solve the engine m'ment issue as well as the fridge charge issue.


While waiting next morning in Ceduna for my slot in the service qeue, I fitted a new half of an Anderson plug, re connected & immediately the engine m'ment light disappeared & the car drove like always & quite OK. Towed & traversed the sandhills of Googs all OK and it ran beautifully - like normal. However, the battery did not charge for the whole 2,000 km trip.

What the hell is up?

Why, when I was mucking about removing the trailer Anderson plug, adjusting terminals etc after the tractor place, did it not come out of limp mode - but it did next morning?

More importantly - how do I fix the faulty engine managment issue it if it happens in remote regions?

Cheers for any thoughts. :cheers:

I am guessing you have a earth fault, is your earth on your trailer connected to the earth on the patrol`s chassis or direct to the Patrols battery?



Also as it was pointed out to me on Xmas day when I was stranded with faulty 02 sensors

BUY A BLAZT cable blaZt - Infiniti, Nissan software scan tool, data cable, reset check engine light

Here is how to check the engine fault code and clear it.

HOW TO SWITCH DIAGNOSTIC TEST MODENOTE:
+ It is better to count the time accurately with a clock.
+ It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit
has a malfunction.
+ Always ECM returns to Diagnostic Test Mode I after ignition switch is turned “OFF”.
How to set diagnostic test mode II (Self-diagnostic results)



1. Confirm that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
2. Repeat the following procedure quickly five times within 5 seconds.
a. Fully depress the accelerator pedal.
b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the MI starts
blinking.
4. Fully release the accelerator pedal.
ECM has entered to Diagnostic Test Mode II (Self-diagnostic results).



How to set diagnostic test mode II (Heated oxygen sensor 1 monitor)
1. Set the ECM in Diagnostic Test Mode II (Self-diagnostic results). Refer to EC-52, “How to set diagnostic
test mode II (Self-diagnostic results)”.
2. Start Engine.
ECM has entered to Diagnostic Test Mode II (Heated oxygen sensor 1 monitor).
ECM will start heated oxygen sensor 1 monitoring from the bank 1 sensor.
How to switch monitored sensor from bank 1 to bank 2 or vice versa
1. Fully depress the accelerator pedal quickly and then release it immediately.
2. Make sure that monitoring sensor has changed by MI blinking as follows.


How to erase diagnostic test mode II (Self-diagnostic results)
1. Set ECM in Diagnostic Test Mode II (Self-diagnostic results). Refer to EC-52, “How to set diagnostic test
mode II (Self-diagnostic results)”.
2. Fully depress the accelerator pedal and keep it for more than 10 seconds.
The emission-related diagnostic information has been erased from the backup memory in the ECM.
3. Fully release the accelerator pedal, and confirm the DTC 0000 is displayed.

I thought... and has been my experience... that when a car goes into limp mode in order to get it cleared you have to disconnect the battery for some time for faults to be cleared. Hence why it was OK the next morning (presume you may have disconnected the battery to fit anderson plug), and why you didn't see an 'immediate' fix to your limp mode problems (simply unplugging and replugging the plug would not clear the codes).

Not sure why an anderson plug would cause limp mode problems, unless ECU picked up non charging issues.

My 2c worth.

Cheers,
Josh

more info

Thanks blokes -

I will copy that diagnostic instructions & carry it - but phew, not sure I can do all that if broken down in the bush.

Sorry, forgot to say I twice disconnected the battery - 2nd disconnect was for half an hour - in an attempt to get system restore - or some such forlorn hope!

Trailer is earthed through trailer light connections - a seperate, conventional round trailer lights plug to the charging pAnderson.

Cheers

Hi Rick, it's Rick.

Get the Blazt cable and software. Run it on little laptop for car or your good laptop if you want. Can read codes and reset them. Tells you more about the car than you can imagine. ie, the two temps for the auto etc. So much info to be had. I have plans for a diy vid for it soon. Deditcated to 4.8's as it's what I've got. Watch this space......

Actually, I'm with the vid man right now. I'll annoy him about it.

Hi BowTieGQ,
I've been looking at getting one of those Blazt cable and software setups for a while. Did you get yours direct from the above link? What sort of $$ did it end up paying if I can ask?
I've got a 02 4.8 and the Blazt system looks the goods.

Im pretty sure it was BowTieGQ who gave me the best advise I have ever been given for free, " buy the Blazt cable" which I did THANK YOU! THANK YOU! THANK YOU!

Mine cost about $120 for the cable and software and arrived just a couple of days later, They even replied to my email on boxing day

That cable and software has been the best tool I have ever brought, cant thank you enough

I use a a 10" netbook, which is always with use when we travel, and the cable lives in the glovebox full time

rmoore does your anderson plug at the back of your patrol connect direct to the battery or to the chassis?

have a look around this site How to wire your camper for wiring ideas, because to me it sounds like you have a earth / wiring issue, or even a corroded breaker

I forget what it cost exactly but about $200ish for cable and software. Nothing it can't do. Well almost. It is a work in progress but updates are free so anything is possible with what you purchase today. I have a beta version that does ecm, bcm, tcm, abs, srs and others but not needed for Patrol. Runs a full virtual dash with more info than can fit on the screen but is selectable to show what gauges you want.

The gauges display in old school fashion with a needle but also show in the centre the actual reading be it voltage or other.

You can even do logs of all kinds of things and compare with a default log to see what is wrong with yours.

The more of us that use it the better we get at dealing with our issues and the better the developers can add stuff based on feedback. I have added heaps and they always listen and improve if possible.

OK, will suss the earth issue asap. Thanks for the diagrams, etc.

Yobbo48, I'll need to look in daylight hours, but methinks it hooks direct to the battery.

Bowtie (Rick); Appreciate your suggestion. However, I don't want to carry the laptop in the bush as it's just one more unnecessary item. I have a 7" GPS touch screen with moving map function & Ozi and 1:250,000 topo maps + hema maps etc. No other need for a laptop - when I get back to civilisation I can talk on the phone for all other matters. I sure don't miss emails - one of the reasons I go to the outback is to leave all that crap behind. Thus I am a bit reserved about getting a Blatz cable. But I am still listening to your suggestions.

Cheers

Fair call mate and agree with you. Can leave it at home anyway. Just handy when travelling. I have an onboard laptop to do gps and other things so for me not an extra item to carry. Lives on special shelf below glovebox.
