Hi Guys/Gals I have been having the same problem with almost all Nissan Titans and can't seem to chase it down. I've used the search on the forum and google but nothing. I hope someone has come across this and knows whats going on.
Details- Ultra Start 1272/3085/3295, CrimeStoppers RS7-G5, RS2-G3 always using a fortin evo-all. Seems that as soon as I program the evo-all the trucks seem to have door lock problems. If you start the vehicle with the remote starter or the key the doors auto lock if the blower motor is on. I found this out by testing if heater works with remote starter. If you leave the heater fan off the locks stay where they were left, doesn't matter if you use the starter or the key. BUT, even with the vehicle running if you turn the blower motor on the doors will lock, you can turn it off and back on and it with try to lock again. The bypass and the starters were wired D2D, fortin bypass updated as per fortin website.
I have disconnected the can-bus wires, wired bypass W2W, turned lock functions off in fortin, disconnected arm/disarm wires(in empty pins at bcm), even unplugged every wire from starter and bypass and the trucks still act the same way.
Any help would be great, if I've missed any info please ask I will reply asap.
Thank you

On all Titans I have worked on I tag the arm and disarm wires in the driver door at the main switch for lock/unlock. Both are negative and disarm is double pulse. Try that and see if that fixes the issue.

No one has come across this? I have done many Titans and have narrowed it down to the Pro-4x, the others have not done it.

Although, there are no such complains with this automobile, yet if you are still facing the similar issues, it is advisable to get it inspected by a professional auto centre. A proper look can give a better idea for the problem.

I have not used that unit on that vehicle, but I have not run across this problem. Only question I would see is are you using diodes on the alarm wires? Some units use a common ground rail internally so I could see weird things happening like this...
Think about if the blower motor is off ground is available somewhere and when the blower is switched on the ground is removed. Its a short circuit to ground on a ground activated signal for sure but where I haven't got a clue.
