Bonjour à tous,
Quelqu'un connait les valeurs usine des hauteurs de suspension pneumatique pour RAM DT 2020.
Suite à une erreur de manipulation j'ai effacé ces valeurs.
Je me sers d' ALFA OBD.

Hello everyone,
Does anyone know the factory values for the air suspension heights for RAM DT 2020.
Following a manipulation error, I erased these values.
I use Alfa OBD.

Le NRH est la hauteur de caisse normale.

J'espère que ce sont des informations utiles jusqu'à ce que quelqu'un avec une suspension pneumatique réponde.

I was able to activate the LED bed lights after I installed the kit.

CBC Config I/0

Bed Light Switch Input Present - Pin G16: -> Yes

Connector F Pin 6: Baggage Compartment Lamps Output Present -> Yes

2014 CBC Config I/0 & FEAT.:

Bed Lighting Present - Pin A5: -> Yes

Hopefully That's new information and will help someone.

So they come on with the door open, or you can push the button at any time and they will come on. Even works well with the Decked drawer system as the LED's in the lights are designed to shine over the top of the drawers.

So I installed the bed light kit in my 2020 3500 CC LB SW Larime HO Cummins. However, I have a couple questions regarding AlfaOBD (I have the bypass installed and MX+).
1) Most Important: How do I create a backup of the current state before I make any changes?
2) On the "Home Screen" - I chose RAM 3500 (D2,DD,DR); Body Computer; Body computer MY2020+ PowerNet
3) Then under "Select procedure to start" I chose "Car configuration change"
4) I see the:
CBC Config I/O
- Bed Light Switch Input Present - Pin G16
- Connector F Pin 6: Baggage Compartment Lamps Output Present
BUT, I can't find/see
- Bed Lighting Present - Pin A5

The only A5 I find is 2014 CBC Config I/O & Feat: Front Park/Signature Lamp Right - Pin A5

I found a video by Kyle Talbot (https://youtu.be/w-RvP93iR3k?t=470) for a 2018 and he selected 2014 CBC Config I/O & Feat: Truck Bed Lighting Feature...which I also don't have...

Any help is appreciated.

Thank you.

anyone?

I’ve got a 2020 and the security guy module is above the driver side kick panel. Way up high. Behind the tranny release box.

Raife · May 19, 2023

I have the bypass all installed and operational...I just can't find the correct settings (particularly the CBC Config I/O & Feat Bed Lighting Present - Pin A5).

Thank you.

2019+ HD Ram bed lights are wired differently than the pre-2019 bed lights, so there is no Pin A5 circuit for the bed lights (that is now the right front signature lamp circuit for the headlights).
All you need is:
CBC Config I/O: Bed Light Switch Input Present - Pin G16- YES

CBC Config I/O: Bed Lighting Present - Pin D6- YES

CBC Config I/O: Connector F Pin 6: Baggage Compartment Lamps Output Present- YES

Raife · May 19, 2023

Unfortunately I get nothing with turning those on...

Check the wiring install then. Make sure you didn’t use instructions for a pre-2019 install.

Raife · May 19, 2023

So interestingly the new switch in the bed will turn the cargo light (the one on the back of the cab) on and off.

~~I'm pretty sure I used the latest instructions, but don't have them on me now.~~

Just checked the instructions and using ones dated December 4, 2019.

Based on the switch working, but the lights not working any thoughts on where to check regarding the install. The connection under the dash was not fun...

Thank you.

Not sure if the HD is the same as the standard Ram. Also 2020 year is going to be different than the 2019, RAM made a lot of changes from the 2019 DT to the 2020 DT on the BCM and ECM setups from my understandings.

Did you make the correct wire modifications under the hood too?

The only difference between those two is the Z automotive one has a splitter providing an extra OBD port, that’s it. They both serve the same purpose, bypass the the same way, and install the same way. Neither allow access to the radio module.

Are you speaking on just the radio because I know that somewhere it states its on a DMZ.. im trying to figure out if that's referring to the RFH (radio frequency hub).. and has anyone been able to make additional keyfobs?

Based on another forum, I think my connection under the hood may be incorrect (C3, PIN 17) as that is the cargo lamp circuit as opposed to the switch circuit (which is apparently the under dash C7 PIN 16). I'll work on it this weekend.

Raife · May 26, 2023

My connection to the C3 Pin 17 was incorrect. Now in correct slot and all working great!

I can confirm many of the listings in the above two links work on the 2021. I changed the drop-out's as well as added in the bed lighting on my 2021. Made some other changes to 5th Gen trucks owned by others in the club. I also know that the bypass cable from the 2018 works on the 2019+ but you have to flip the slots. IE: (assuming you have the yellow and brown cable) if the yellow cable was plugged into #4 it should be swapped with #16 on the OBD plug.

Resurrecting an old post, sorry. But I just installed the cargo bed lights and made the changes in AlfaOBD, but they don’t work. They don’t turn on at all. Any suggestions? I did not let the truck reboot after every change I made, so maybe that’s the issue?

LoveMachine · Jul 22, 2023

Figured it out. I wired up the ECM based on looking at the diagram as if it was showing where to put the pin from the plug side. But the diagram shows where to pin it from the wire side. Stupid mistake, I know, but I feel like it’s an easy one to make. Lesson learned and hopefully it will help someone else out too!

Jim S · Sep 14, 2023

I need to calibrate my speedometer to the new tires i got. OEM's were 275/55 - 20 . I got rid of the crappy Bridgestones and replaced them with Hankook Dynapro AT that are 60's not 55's.
Can anyone point me in the right direction?
