2008 Nissan Pathfinder S - Standard Key - OEM Alarm

Fortin EVO-ONE With NIS2 Harness

Guide Followed: 75611

Unit was flashed to recommended/newest firmware prior to install.

Service No: 002B07200206

Everything is installed and working (As far as the Remote Starter Goes). When using the OEM Remotes the vehicle will lock and unlock as it always has. However, when using the RF642W remotes, The remote start works flawlessly (Push button, parking lights on, start/Crank, Run) The lock button locks the doors, but the unlock button also locks them (and does not unlock). The OEM Remote will unlock the door as normal with the remote starter running, but I would really like to not have to carry two remotes with me.

Vehicle Running

Oem Remote: Only Solid Yellow is on, No Blue Flashes

RF642W: Lock - Solid Yellow, Blue Flash - Locks Doors
RF642W: Unlock - Solid Yellow, Blue Flash - Locks Doors

Did I miss a step? Enable/disable a wrong option?

Any help is greatly appreciated. Thank You in advance.

Well, good news is that the door locks are analog connections. Meaning, easy to test. 


So first would be to check the lock-unlock and disarm connections. 

  • Purple = Lock output
  • Purple/White = Unlock output
  • Orange = Disarm connects to Purple/White not purple


Also, when the module receives unlock, the blue led should flash twice. If it does not, make sure antenna is in the blue port and not the black port. 


Being analog connections, you can also turn off option A1.

Thank you for the reply.

I turned off A1 as suggested. The problem turns out to be user/installer error. When the unit was installed the Purple wire and the Purple/White wire were inserted into the wrong places on the BCM connector. The Orange wire was run to the Purple/White wire correctly. I swapped the places of the Purple wires and everything works as it is supposed to.

Thank you for your time and help with this issue.
