Automatic headlights - Stalk & sensor transplant into an S

Thu Mar 30, 2017 8:45 pm

Stalk pn: 25560-3KA8E combination switch

Optical sensor pn: 28576-1HH0A

I'm going to try installing the combination switch and sensor to see if I can get auto headlights in my '15 S.

I have an independent mechanic who says his Nissan Consult works on a 2014. Anyone know if that will work on a 2015? I think the BCM needs to be programmed to turn on the auto headlights.

Don't even know it the wiring for the sensor is there. If not I'll wire it up to the BCM.

Let's have some fun.

Here are my notes on how to make the connections.

Unfortunately, there are no wires on the M24 BCM harness for the Optical Sensor input (#14) and the Sensor Power Supply output (#17). There is however a wire for Sensor Ground (#18).

I wired everything up and cut the hole out for the Optical Sensor next to the AC sensor.

Here are some pictures:

Combo switch (stalk) - no need to remove the steering wheel. Just remove the top/bottom covers (2 screws) and there are 4 screws holding it together, 2 each on the left/right sides.

Connector M24. The paperclip is on Optical Sensor Input # 14.

Cutting the trim that holds the Optical Sensor. There's a pattern of the sensor hole on the bottom of it, which make it easy to cut.

Here's what needs to be done in Consult 3+ in order to turn on the Auto Headlight feature:

I now need to find someone with a Consult 3+ to make this work.

So I contacted Jim (aka WattsLeft of LeafSpy) and asked if LeafSpy Pro is able to turn on the Auto Headlight function.

Turns out the newest version is capable of doing just that.

I have an older version on an Android phone that I bought just for LeafSpyPro when I wanted to change the settings on the door locks. I haven't looked at it since.

I'm going to check it out when I get home.

Here is an image I got off the web of the appropriate service screen:

Either this will work, or I did something wrong with the wiring. We'll see...

Got the Beta version of LeafSpy Pro and although I can change the settings, the auto light function still doesn't work.

I've done some more homework on the Auto Light feature. I even went so far as to track down the different versions of the BCM which I found out should not be program-specific but instead build-date specific (ie. 284B13NF0B for 10/2014-8/2015, and 284B13NF0A for 12/2012-10/2014).

After looking at the combo switch inputs/outputs thinking that maybe certain wires could be missing, I've concluded that it can't be because other common functions are associated with Output 4 / Input 3.

I found a manual setting for this feature in the BCS manual. Apparently, I need to manually set the "Auto Light" under the BCM configuration to a setting of "With".

The next step is that I need to get this setting manually set and try again.
