Pathfinder MOST Bus Fault

I'm experiencing a frustrating issue with my 2002 Nissan Pathfinder diesel. The MOST bus seems to be faulty. Symptoms include no audio output, the entire audio system is dead, and the navigation system is non-functional. Car diagnostics also show an error stored in the error memory. Given the mileage is at 91687 km, it's probably a defect in one of the control units installed in the MOST bus. Anyone experienced similar?

Sounds familiar! I've had similar issues with my Pathfinder. No tunes, nav system kaput... Super annoying. Is there anything happening intermittently, or is it just completely dead all the time?

Good question. It's completely dead all the time. I've checked the fuses; those seem fine. Did you manage to find out what the specific culprit was in your case? Was it a specific control unit causing the whole bus to fail?

Yep, sounds like the same headache I had. Unfortunately, I didn't get down to which module was faulty. I ended up taking it to a workshop, as diagnosing MOST bus issues requires specific tools. I'd recommend doing the same rather than chasing your tail.

Thanks for the insight. I suspected as much, and I'll follow your advice and book it in. From what I've researched, I am anticipating a repair cost of around 1000€ to fix it. I appreciate the shared experience!
