I have a 2015 I/C CE300 that occasionally the NCLB won't disarm. I have had three different drivers have it happen to them so I don't feel as though its a "procedure" issue.

My question to the masses is there a way to kill the system so to speak when it acts up? Is there a fuse or breaker that can be removed to deactivate it? Trying to find a simple way to get the thing quieted down after the bus has finished its route. My wife drives the bus and I need to figure out an easier method of turning off the thing than having her crawl under the bus and disconnect the horns..... I drive our longest route and get back to the shop after she does.

I am by no means wanting to disable it for good, just shut it down should it act up.

Thanks all!!

there is a post trip inspection relay just above the chassis fuse holder in the left compartment by drivers window , if you pull that it should shut down, not sure though
