Enable Loudness audio setting on 8.4UAQ on Alpha OBD

[Black-Wolf]

Actually after reading this my harness doesn’t allow it to connect to the radio.



From the harness provider:

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

Thanks for the clarification! That makes sense!

My 2017 doesn't require a security bypass and it won't connect to radio, well it connects,but can't make changes. Think the warning says you need a blue harness or something along those lines.

So I found the blue adapter that is needed, perhaps some adapters have built in functionality,but they are mostly used for Fiats in Europe. Saw someone with a Jeep needed a cable for proxi alignment as well.

Ah same one as I have. Now I know I won’t have access either. Thank you.
