Alarm going off spontaneously

[RichMorris]

My 14 3500 Aisin started spontaneously alarming about one minute after locking with the key fob. It happened several times in a row. The EVIC message said the remote start was blocked and to start the truck to reset. I tried several times but nothing changed. Of course this started after 6 pm and the dealers mechanics had all left for the day. Any ideas? Thanks.

The radio hub flash recall was released to fix problems like that. Mine did the same thing a couple of times but hasn't done it since I had the flash done. I think it's the P15 recall, I don't have the paperwork available so I'm going by memory.

Try disconnecting the battery's until you can get it in and have it scanned. There should be a monitor to show why the alarm was triggered.
