2013 Nissan Pathfinder R51, Remote Start/Alarm, Lock/Unlock, Immobiliser

Yes, something is wrong with the Unlock output. It should be similar to the Lock output. I've heard that you can damage them with in appropriate connections. You could try using the Disarm Output. It's not exactly the same functionally as Unlock but should be OK for testing. On the Immobilizer system, the R/S should duplicate the regular key startup and turn on the chip sensing to see the keys' chip when it outputs the ignition wire outputs. Your Pathfinder should R/S with the 556U unplugged and a key held next top the ignition cylinder or inserted but not turned. Your vehicle has one Ignition wire, two Starter wires and two Accessory wires. All should be isolated and powered during a R/S. This would require an additional 30/40 Amp SPDT relay controlled by either (-) Starter or (-) Accessory and the Pink/White Flex relay programmed to either Starter or Accessory. Soldering is fun!

I will send the shop a message regarding the issue and see what can be done as the unit is a bit useless if i can't unlock Regarding the rest, it seems that I need to rewire some connections. I will connect the second starter wire with a 30 SPDT relay as you have suggested. My only problem is I cannot locate the second ignition wire. Everything suggests that there is a second one (which brings up my dash) but I cannot find it anywhere. Every other post on this forum says it is in the ignition harness plug but mine doesn't have it. All other colours match up apart from that one. So i believe i have 1 acc wire, 2 ign wire and 2 starter wires. This explains why my dash only shows up when my key is turned to IGN - and since I am missing that second wire, my dash isn't lighting up and therefore my immobiliser isn't reading my bypass module. I simply don't know where this second ignition wire is :(2013 Nissan Pathfinder 140KW

Here is what the main ignition connector looks like for U.S. R51 models : There is no IGN2 on U.S. models. Do your wire color and locations match the photo above?Soldering is fun!

This is what my harness looks like: I have: Green: (+) 12V Brown: ACC Grey: Starter 1 Light Green: Starter 2 Red: Ignition 1 Black: - I just assumed was ground (-) as it was black so I never tested it, but could it be possible that this is in fact the second wire since the harness that you have shown does not indicate a GROUND (-) 2013 Nissan Pathfinder 140KW

Possibly, I've never seen a Chassis Ground in a high current ignition connector but I've seen Black wire used for various type wires. Seems your wiring is very different from U.S. models.Soldering is fun!

Ok i will give this one a test tomorrow and see if it is IGN2 or ACC 2 as it is 23:15 now in Australia, QLD. I was also going to wire the second starter like this with a SPDT: 30: Starter 2 85: 200mA Starter Output (-) 86+87: +12v (Constant/fused) 87a: unused 2013 Nissan Pathfinder 140KW

Yes, relay wiring is good. It's almost tomorrow in OZ....   Soldering is fun!

ALso the pink/white flex relay. I thought that it automatically gets changed depending how it is wired up. Or do I need to program it myself, depending on if i even use it based on that black wire.2013 Nissan Pathfinder 140KW

The Pink/White Flex relay comes set as IGN2 as default. You can change it via option programming to ACC2 according to the 5305 manual. Guess it can't be set to Starter2. See Menu 3, Item 6. Soldering is fun!

Ok well I will be home in a few hours (at work), I will first test that black wire and confirm whether it is an ACC2 or IGN2. Ill then do the following: 1) connect the red/white wire to a constant 12v fused source 2) connect the pink/white to either the ACC2 or IGN2 (whatever that black wire is) 3) connect a SPDT relay 4) Remote start and keep a fire extinguisher nearby hahaha2013 Nissan Pathfinder 140KW
