2020 Ram 3500 Flatbed install

[Sleepersilverado]

I thought I would put this on here for any future guys looking for this information. I searched the internet high and low and never found a direct answer on how to get rid of the Blinker out warning and the blind spot error message that I got after installing a flatbed and removing factory led tail lights with blind spot sensors. I was able to piece the info together through multiple sources so wanted to leave it here in one spot.

You will need alfa obd to change these settings. I am no expert in alfa but found enough information and messed with it enough to fix these problems.

To Disable Blind spot alert:

-Connect to your BCM
-Go to active diagnostics tab
-Scroll to bottom and select "car configuration change"
-go to "cabin net RBSM right blind spot modular"
--select value "not enable"
-go to "cabin net BSS blind spot sensor / LBSS left blind spor sensor"
--select value "not enabled"
-go to "doors blindspot mirror present"
--select value "no"
-go to "vehconfig 7- active blind spot present"
--select value "no"
-go to "cust.set menue 1-blind spot alert can present"
--select value "no"

To fix the hyper flashing and blinker out warning:

-go to "rear light dts disable"
--select value "yes"


Hope this helps. I am going to play with combining the tails and blinkers like on the newer trucks, if I figure that out I will update here.

What brand is the bed?

I like the look. Kind of combines the look of an expedition style and utility style.

It is a custom bed made by Herrin welding / Herrin Haulers. I would consider it most like a goose neck service body but they refer to them as a Custom Ultra legacy Hauler.

I can confirm that this set of instructions works on a 2024 2500 but there were two typos but infortunately I don't recall the correct spellings!....cust.set.menu is cust.sc?.menu and rear light dts disable is also slightly wrong. It was my first time using AlfaOBD so I struggled but did get it done.
