Seeking Advice on 2005 Nissan Terrano's Fault Stored Warning and Central Fault Memory Lock Activation

Hey there! You're not alone. I've also owned a Nissan, a 2002 X-Trail to be precise, and ran into something pretty similar a while back. My beast was showing an engine saavy too, and I was certain it had to do with the Central Control Unit (CCU). From my experience, these faults are usually triggered by the CCU when there's some issue with the electrical bit of your ride. I took my X-Trail to my local garage, a place I trust, and they did a full diagnostic check to determine the root cause. Turned out, the engine control module needed a bit of work, specifically, the connectors were a bit janky. It wasn't serious, but it could've led to some major issues down the line if not addressed. After fixing that, my X-Trail ran like a dream. I can’t say if this is precisely what's up with your Terrano but it could be worth having checked out. And remember, don’t stress too much, it's a common issue, and usually not a major one. All the best with solving this!

Hey there! Your advice really puts my mind at ease, and I'm glad I'm not the only one facing this issue. I do have faith in my local garage as well, so it's about time I visit them. Quick question though, do you remember the ballpark figure you paid for the repairs? And has anything else cropped up since it was fixed? Really appreciate your help, cheers!

Hey! Yep, indeed, had to shell out around 625 quid to get it all sorted out. The actual component area we thought was defective had to be addressed, which ran up my bill that much. Once that was done, however, everything was back to normal. And ever since the mechanic got on to it, the Central fault memory lock has been acting just fine, no issues whatsoever. Hands down, best thing I ever did was to listen to my guy at the garage. Money well spent, I reckon. After the fix, my trusty X-Trail has been chugging along without a problem. So, rest easy, it's very likely your Terrano will be good as new. Cheers!

Hi again! Your detailed response is a huge reassurance indeed! Seems like the trouble and cost are worth the peace of mind in the end. I'm going to ring my local garage first thing tomorrow and hope for a result as great as yours. If anything noticeable comes up after the repair, I'll be sure to share it here with the community. Really appreciate the guidance and for sharing your experience. Cheers!
