No Tailgate Ajar Warning (MY22)

Looking at the schematics, it’s the same operation as the hood latch:
It’s looking for about 1700 ohm resistance when the tailgate is closed, and open circuit sets the tailgate ajar indications in the cluster.
So, if you enable the two settings in AlfaOBD, and if your cluster is capable of the feature, it will show the tailgate ajar indications since there is an open circuit from not having the correct wiring or latch

This is a known working/programmable fob for the 5th gen 1500’s:

AlfaOBD can’t program the fobs, but I can set you up with a way to program them yourself if you want to PM me.
Ok thanks ! Let me check my bankaccount lol. im looking at doing the brake controller to soon. Thats a good price for the fob on ebay..

I believe I read 4. Could be higher, but I know it's at least 4. Look farther down, Jimmy said 8.

That's an amazing price!

Can I buy one FOB with tailgate open (for myself) and will the other two still work? I’d hate to have the others deactivated.

How much are you guys paying to get these FOBs programmed? And where did you go (dealer/shop)??

What do you all do with left over wiring harnesses?

I have a few--LED bed light install, headliner from installing intermittent wipers, tail gate from installing tailgate ajar. The clips are damaged or a few of the clips are broken. Ends and wire are still fin

Anyone tried this on a 2500? Parts the same? I have the 22 Laramie 2500. I can drop tailgate with my key fob or a button on the truck. Bed lights/cargo lights do not come in when tailgate is opened. No tailgate ajar warning. I enabled it in Alfa but haven't had the opportunity to check pin 26 yet. Thanks in advance!

Won’t work for an HD Ram. There is no such tailgate latch part that has an ajar sensor for the HD’s, and a 1500 latch won’t fit.

Thank you, I appreciate it! Wondering now if the BCM has the pins for it and it's in the software then I could set up my own switch.

Hey all, any instruction for programming using a JSCAN? Also, how do you know if you have a small screen? My Build Sheet says Instrument Cluster Theme Level 1. I'm guessing I'm good to go to do this mod, except I just use JSACN.

Curious as well. I can see the tailgate ajar option but no F pin 26 on JScan.

CBC Config I/O: Connector F Pin 26 - Set to Yes
ECUConfig 4: Tailgate Ajar Indication - Set to Yes

Ok so JScan says it’s these last 2. Look for “Ajar.”
