Hi,

I have a missing bluetooth, sdars, tpms, and audio module under the driver seat

What is required to make the dashboard work? Right now its just flickering.. I want it to enter it's natural state. I'm guessing just the Bluetooth module

Ok, so you are trying to get the screen to stop the boot loop by using the minimum required modules for that to work.

There isn't a lot of people around that would have that exact answer from trying to recover flooded Jags. There is a good reason for that, but anyway.

This will require some trial and error with fiber loops to see what will work, it could be no modules at all, or all of them. All these modules are connected by an orange fiber optic cable in a series, called the MOST network. It is like a strand of Christmas lights, if one bulb goes out, the entire chain goes dark. This causes the flicker and boot loop that you see. Here are the diagrams.

You want to add a fiber loop to complete the circuit for any module missing, or maybe all of them at once using the fiber optic lines coming from the main harness that enters the under seat area to just return the signal. Here is some I bookmarked that could work but you need to confirm compatibility on your own. Maybe if you post a picture of what plugs you have sticking out, someone can chime in with what you would need to execute the bypass.

For sure you will still have dash errors if any expected modules are missing unless you code them out from the configuration, even if the main screen becomes operational with the bypass.

Found someone that did similar but shows what a battle this can become, good luck.

Thank you very much. I've been asking about this for a couple of weeks couldn't find an answer. Appreciate your reply👍👍
