Tailgate Open Warning Light

[Captkent]

Another thing I found odd under stock programming is that the bed lights will turn on when you open a cab door, but not the tailgate. Excellent programming FCA.

On all my other rams the bed lights come on with tailgate opening same as cargo light

So I’m waiting for my sgw and obd adaptors to arrive to use alpha. For those who have done it, enabled the tailgate ajar light. Is it under the body computer or sgw module. Can’t wait to get this enabled. Also will this allow me to program two new keys with the tailgate release button ? I’m assuming so.

In AlfaOBD, you do go under "body computer". Once in there you select "car configuration change". If my memory serves me correctly there were 2 different things you need to check. One is ECUConfig 4: Tailgate Ajar Indication. This was already selected as "yes" for me so I left it as is. The other is CBC Config I/O: Connector F Pin 26: Truck/Liftgate Ajar Signal Input Present. This was set to "no". Changing this to "yes" is what made my tailgate ajar warning work properly including cargo lamps coming on with the tailgate down. Hope this helps.

I don't think you can program keys with the Alpha OBD. Keys need to be programed at the dealer

Actually, apparently you can. I haven't done it myself but supposedly all you need is the PIN number of your truck from your dealer. Word on the street is some dealers will give it to you no problem while others will not.

Good to know, thanks.
Let us know how you make out.

Awesome thank you

Because I'm not currently on good terms with my local dealer (long story) I wouldn't give them the satisfaction of saying no to me about the PIN. Luckily, I'm happy enough with just 2 keyfobs so I don't really need it. There's also an android app that can supposedly pull the PIN for you. It's not free and I'm not sure if it works with 5th gen trucks.

Awesome thank you

No problem, good luck!

So happy got Alpha ODB the obd2 adaptor and the sgw bypass and fixed it. The tailgate ajar light was enabled but the trigger wire was disabled. Thanks guys.

Now to get the new key fobs from the dealer and program them and set up the remote tailgate release.

Glad it worked out for you! Good luck with the keyfobs.

2020 Bighorn Level 2 Night Edition. On my spec sheet but did not work. I used AlfaOBD and now it works. Cargo lights also come on when I open Tailgate. Build date 5/20.

I also changed drls from low beam to turn signals. Amber against black paint looks awesome!

Also disabled fog light drop out with high beams.

Any chance you remember the settings in Alfa for all of this? I tend to get a little overzealous when pushing buttons so I'd like to take the word of someone experienced so I dont ruin my BCM.

Thanks in advance

I don't recall specifically but see post #47. I think that's what I followed.

I have a new 2022 with the same issue. Anyone else?

AlfaOBD Known Changes 5th Gen

I saw this being mentioned in the AlfaOBD thread that it would be nice to have a comprehensive list in one thread of known changes that are known to work, so I figured I would kick it off and add what I know and update to the first 3 posts that I will reserve for future submissions. I come on...
