If you have a 2018+ RAM and would like to perform diagnostics or make changes to the modules of your truck using tools like AlfaOBD or AutoEngenuity, this bypass is for you.
Does this allow access to all modules?
It has been tested connecting to the BCM and RFH. Since it bypasses the security module for both the CAN C and CAN IHS, almost all modules should be good. The one exception is the radio. The radio does not directly connect to the either CAN of the truck, it is hung off of a DMZ on the security module to protect the truck's CAN in case the radio would be comprised via the 4G cellular functionality.
Does this work with 1500, 2500, 3500, etc?
There are two different versions. One for the 1500s, and one for 2500s and up.
How long does it take to install and is the install permanent?
It take about 5 - 10 minutes to install. Installation instructions will be provided with your purchase. It can be removed in the same amount of time. The factory OBD2 port can be put back in place in less than 2 minutes without any tools.
What programs have been tested with the bypass?
At this point, AutoEngenuity, AlfaOBD, and Autel have been used with the bypass.
Should I leave the bypass installed at all times?
That is up to you. Installing the bypass does make the truck less secure by enabling the OBD2 port for use with diagnostic and configuration utilities not provided or authorized by FCA. That being said, the harness rewires the truck to be just like all previous model year RAMs. I would recommend that you remove the bypass before taking it to a dealer.
