Nissan Navara NP300 4wd system fault Error Investigated and FIXED for FREE ! P1819 Fault Code 

Thanks you are so helpful an knowledgeable on Bavaria enjoy watching

Yes, it’s important to give these motors a workout now and again. At least a couple of times monthly in my opinion. I found out through experience with my Land Cruiser Amazon where the centre diff lock was actuated often enough but the rear axle diff lock, motor actuated, was not needed for years at a time. When I did come to use it, I’d lost it. No error codes but no diff lock engagement ever again. In this case I didn’t bother repairing it, because I never used it. The new Ranger is a different matter because it does more extreme farm work and, due to experience, I’ll certainly engage it regularly. The other 4wd modes including the centre diff lock are used regularly anyway during day to day work. My 2014 Ranger also has electronic shifting for low range and high 4wd and is used very regularly in low range, so it has never been a problem [touch wood!]

Lovely job Simon 👏👏👏👍👍👍⭐️⭐️⭐️⭐️

Hey Simon, I have this same issue and took it to Nissan with the following conclusion from them: "FOUND CODE P1819 WORKED TH DIAG CHECKED PINS PLUG M68 BUT FOUND ISSUE IN PLUG CONNECTORS PINS 1/4 LOOSE. REMOVED PINS AND TIGHTE AND REFIT AND CLEAR CODES. OKAT TIME OF TEST" - So this aligns partly with what you found. However, I can confirm them (Nissan) removing the plug and reconnecting it has not resolved the issue. In fact, the issue is now much more frequent! I could go previously go weeks without the 4WD fault popping up and now it's every time I start the engine. They want £180 every time they diagnose the same issue and I find it very frustrating. 😕

Very good and very helpful video 👌👌🙏🙏🇬🇧🇮🇳

Often drop into 4H and 4L to keep things working. Will go somewhere I can put the locker on my hilux this weekend too.

Boom Boom!! 💥 💥

I charged my battery and the 4wd system fault hasn’t been seen since

That red Christmas tree is so annoying. 🤓🙏🦘
