370z roof won't move warning light on

alcheng

similar thing happened to mine couple years ago, yhe top can open no problem at all.

only when it is closing, the front latch onto the windshield frame no problem but cannot complete the latching at the back.

found the it's the faulty sensor at the top-storage.

FIXED. Thanks to Top Hydraulics for their advice to reset the system AFTER I repaired the wire harness going to the hatch assembly. They told me to remove the common from the battery for 2 hours, cycle the windows than try the top- it worked!!!

I'm having the same issue, the hydraulic pump was recently replaced I've also tried disconnecting the battery. The rear bow will not engage. Top Hydraulics is also helping me trouble shoot this issue.

Check the hydraulic fluid level. Check for hydraulic leaks. If the fluid level is low or if there is air in the system it won't work completely. Klaus at Top Hydraulics told me the system is self-bleeding, which means it will bleed any air in the system automatically, but if there's not enough fluid in the system (from a fluid leak) it will only go so far then quit. I accidentally nicked a hydraulic line causing a leak. The top would only go so far then quit. I replaced the lines and filled it with new fluid. It works now.

Hello gang, I am back at it with a new set of symptoms on my 2010 roadstar. Here are the details:

1) Soft top has been in storage (top down, or open) for about a month. I start engine, no warning lights and all seems good until...
2) I hit the CLOSE button. The storage lid opens about an inch and gives up. Roof open light stays on. The lid drops back down due to gravity but the light stays on.
3) I hit the OPEN button. The motors turn and the lid closes completely. Roof open light goes out and all seems good.
4) I repeat the process again with the same results.
5) I manually raise the roof halfway, start the car and hit the CLOSE button. The soft top closes and latches as it should, and the roof open light goes out - no warnings.

I have not tried to open and close the top again. I do notice that the soft top is hitting and pulling down the storage compartment cover when it opens - which I believe is a sign of weak bungees. I have heard of the top not opening when the bungees are weak, but have not found anyone with difficulties getting the top to close.

I saw no sign of hydraulic fluid leaks in the storage compartment.

Question: Would weak bungees cause the top to rise only an inch or two and then give up? Has anyone else experienced this problem and solved it with new bungees. I need to replace them anyway, but I still wonder if that is the problem. I think I am good on the electrical because the top can be hydraulically latched open or closed without roof open warning lights at the end of travel.

I am trying to replace the fifth bow bungees, and this is a story unto itself.

Part numbers 971F8-1ET0A and 971F9-1ET0A for the bungees on each side is discontinued and replaced by the 971F8-1ET0B kit. However, the 971F8-1ET0B kit is discontinued and replaced by the 971F6-1ET0A kit. That is available by special order from my dealer parts (delivery in one day) for $233.

The same part seems to be available on [URL="https://frsport.com/search?q=971F6-1ET0A"] for $157 plus shipping(?). Anyway, the soft top bungee saga continues.

Brought my Z to a few shops now "pro's & Nissan master techs).
Now that the open/close button has power again my top will open (I have the use the tool to unlatch it from the windshield manually) the top will open all the way and BEEP once done.

However, when I press the button to close the top, it closes all the way, locks in the back, but it does not beep. The second that I let go of the button the top unlocks just in the front and pops back up immediately. I then will have to shut off the car and use the tool to close/lock it to the front.

*If you have an idea on how to reattach the defrost wire to the rear window that would also be great!

Thank you in advance ...

Update: I went through the sensor diagnostic procedure given by Top Hydraulics on their YouTube video, and found that once again I had a broken wire which I had previously repaired. Symptoms different this time, but it was the number 76 connection again (5th bow striker sensor). Top now works but I still may take on the bungee replacement as a preemptive measure.

Update No. 2: Started the bungee replacement procedure but chickened out when I got to the "cut old bungee cords out" step. They all seemed to be in good enough condition and there was no way to recover once they were cut other than to muddle through the remaining 5 or 6 hours of work (per SIDE) if I could even figure it all out. I put it back together and the top would not open because the fifth bow was hitting the back lip of the storage compartment. It looked as though the lid was about 1/4 - 1/2 inch proud of the compartment edge and therefore would not go in. I did more research and found that there is a known problem of a pin coming out of a drag link channel, and the channel needs to be opened back up (NTB14-064). This took about 3 minutes to accomplish once I saw that this was indeed the problem on both sides (note: 3 minutes does not include the manual opening of the soft top because I had already done that). Hint: I used a large screwdriver with a square shaft and put vise-grips on the shaft for more torque. Be careful! The metal you are bending is relatively soft and does not need THAT much encouragement. Top now working again. Here is the file on the Nissan Technical Service Bulletin, and a illustration that I did showing before and after.

How to reset the system?
* I've removed the common from the battery for 2+ hours ...
Cycle the windows ... do you mean to hold the window up switch to set them?

Thanks in advance

I just want to thank everyone who posted on this topic. Our 2016 370z soft top has had a couple of issues. After researching and reading all these posts we have found our issues. I've installed the 5th bow kit and now just this weekend found the broken wires. all is good now. I also bought a Mucar DTC reader. It read all the cars modules and provided me with exact fault codes for my cars top. I highly recommend it for it was only $50, and it works from my iPhone. Also want to thank the individual who led me to the manual. It was for a 2009 but it seems the top has not changed on my 2016.

Totally agree Jill, this forum is brilliant for identifying problems and getting your car fixed without wasting time and money at Nissan etc, esp when it comes to our roofs as unfortunately, they don’t understand them very well, don’t sell parts for them so for any issue they simply quote you a new roof for $15k or some ridiculous price. The forum has helped me many times so I always try and post any usual/helpful info that I come across and of course encourage everyone else to continuing doing so.
It would appear that about 90% all top not working issues are those damn wires held in by that plastic housing that's attached to the deck lid arm. I was aware of the problem when my top stopped half way when opening just before Christmas. I went straight to wires where they bend 90 deg below the bracket and sure enough had the pinched wires. I ended up replacing about 6 inchs of all the wires as while only two were broken they all were very hard and brittle due to the constant bending.
The other good tip is to not put them back into the black plastic housing as the issue will just happen all over again. I just attached mine quit loosely to the arm with Panduit/cable straps.That way they can just move freely, kind of fall naturally and not kink. I even left the hyd lines out a swell as these can also wear due to their very thin walls. Tophydraulics can sell better quality ones if required.

Mine is the same. It opens about a foot and stops. I give it a little love tap, and it opens all the way. The metal cover on mine opens, but it seems to stick a bit first.

To some of you who wants to get rid of that warning light and buzz, here's the solution:
open the battery cover under the hood, there's a small fuse box in front of the battery, on the cover there's the diagram telling you which fuse is for which component, there's two fuses for the roof, one is a big one with a 40A and there's another small one in 15A, I remember it's the 2nd one to the right on the top row.
You can remove that 15A fuse, the warning light will turn off and no more buzzing, so you can drive in peace.



What happens if you remove the 40A "Big" fuse - Obviously the roof will be disabled - Besides that will the roadster function "Normally"?

I already "Pulled" my steering lock fuse and I'm glad I did
