Upper fuse box

[Daveykid]

Interesting... I had no idea there's a fuse box behind the upper glove box. That would be THE worst place to put one, because it's hard as h-e-c-k to get to.

I've personally opened it up and there's nothing back there on my '11 LR4. Here's an electrical wiring diagram of mine and it's pretty true to it, well at least for me.

That's awesome! Thanks for the link @Daveykid. I have a bunch of files that I wish I could share with this group.

Could be anything.
You would need to check which module for the infotainment system is off line .
The modules communicate with each other via a fiber optic cable.

There are fiber optic bypass loops that you can buy and just eliminate one by one.
ie: unplug the audio amplifier, install the bypass loop. If the infotainment screen comes up, amplifier is bad.

I forgot to mention also I was getting parking brake faults but they went away the next day and i was able to clear them out

Please forgive my ignorance

im still trying to figure this one out. I have sent off my radio and there is nothing wrong with the radio. I bought the bypass loop you mentioned and checked the amp it still nothing. Where should I look next?

There are two more modules in the right rear panel, just behind the 2nd row seats.
When you install the bypass loop, cycle the key off and on.
A module that is on line will have a red light on where the fiber optic loop plugs in.

In the past, customers have decided it's cheaper to buy the bypass loop than spend money on a satellite module.

thanks! I’ll check that next

I plugged my bypass loop in both of those and nothing changed.

Can you post your VIN # ?
I'll check and see how many modules are on your fiber optic network.

Thanks

Also when I check my fuses with a test light the radio fuse doesn’t have any power to it
