2001 Nissan Frontier, Autopage RS855

Reverse the polarity of the relay to give a negative signal. Connect 87 to ground and the output on 30 should be a negative..

Does anybody have a tech sheet for a 2001 Nissan Frontier that shows the location/wire color driver's door unlock motor wire, and the door triggers for driver, passenger, and rear doors.

MetaverseWhen you wire up this alarm for double pulse unlock, does the alarm send the pulse to H10/14(pink) first or to the H7 blue wire? I'm looking at page 17 diagram, 2 STEP UNLOCK WIRE CONNECTION FOR GROUND SWITCHED DOOR LOCKS.Thanks

Notes:	*1 Not required for remote start. *2 The ECM is located below the heater box to the right of the accelerator pedal, behind trim panel. The tach is in the top row, 3rd pin left of center of the plug. The VSS is in the 2nd row from the top, 4th pin right of center. *3 Located at the Smart Entrance Control Unit above the hood release in the drivers kick panel. The door lock wires only meter when turn the key in either door key cylinder. *4 If equipped with factory dome light delay, use GREEN/ red(-) for the drivers door and GREEN/ black(-) for the passenger door. Diode isolate each wire. The RED / black may also be found in the drivers A pillar. *5 These wires are for the low beams. For the high beams use RED / green(+) and RED / white(+) at the same location. *6 Use WHITE/ blue for intermittent, WHITE/ red for low, and blue/white high. *7 Unlock requires a double pulse. On vehicles without the factory alarm, can also find lt. GREEN/ red for lock and brown for unlock. *8 A single pulse to the unlock wire will disarm the factory alarm without unlocking the doors. *9 It is purple on the 2 door models, and blue/red on the 4 door.

Look at the diagram on page 18..it includes use of the pink wire. The pink wire should give a double pulse unlock along with the blue. Maybe you meant page 18 instead of 17..my electronic PDF of RS-855 install manual has it on page 18. Look at the setting on page 21 alarm feature B programming..set it to double pulse. Also look at the Alarm feature C programming on page 21 Tell it the pink wire is to be used for two step unlock output. I understand it is the default setting, but, go verify it nonetheless. There is a way to to tap into the door lock timers on nissan's to use the priority unlock that the factory remote fob's use..Unfortunately, I don't know that circuitry..blah..would come handy on both of my nissans...lol.

I figured out which wire controls the central lock, but I am confused about which wire is for the door lock motor. There are two GREEN / WHITE wires at the SECU. One is a heavier gauge wire than the other. Is the door lock wire usually a heavier guage? How do I test the wire to see if it is the right one? All the tech sheets say to test it with the key cylinder. What does that mean?

Take a look at this link: Lock tips

I found the wire. It was the heavier gauge wire out of the two. I tested it and only the driver's door locked. I'm finished with the alarm, but I haven't started to program it yet. Anything I should know about the process, or is it straight forward?

I got everything working, almost. The remote start works great. This isn't a bad alarm at all. I cut the driver's door lock motor wire and applied 12volts to the motor side, and it just unlocked the driver's door like it should. However, when I press the unlock button on the transmitter, it unlocks both doors. I couldn't find the yellow and yellow/red wires at the secu, so I used the alternate wire colors that were on my tech sheet for vehicles without factory alarms. I tested this wire with and a single pulse would unlock all doors. How are alarms usually set up when programmed for double pulse? There is two unlock wires coming from the brain. One wire goes to the relay hooked up to the door lock motor, and the other goes to the central door switch. Does the brain send a single negative pulse to both wires with one press of the transmitter and another pulse to the main switch upon the second press? Also, I went into test mode and tried to adjust the shock sensor, but I can only get the first warning out of it. It is supposed to be a 2 stage shock sensor, but I am only getting a warning and not full alarm in test mode or out. I even set the sensitivity high and tapped on the shock sensor, still no luck. Any ideas?

I don't think test mode will do a full trigger..it is just to verify if the sensor is even working and to adjust warning.. As for the lock..you got me. If you wired it up as the picture below, it should work..
