What’s wrong with my truck

[Nickac]

So I’ve been having weird issues with my truck and random faults.

Intermittent electrical/module issue across multiple systems:

• BLIS fault comes on randomly, clears after restart
• Reverse auto braking unavailable / see manual message
• “Check brake system” warning occurred, cleared after restart
• Audio issue where only tweeters worked — fixed temporarily by reseating the B&O amplifier connector

Issues are intermittent and reset with key cycle

Any ideas?

Adding to this. I have some aftermarket items.

Dash cam
Off road lights
Ham radio

I did stack my grounds from these items on factory ground points with OE wiring. Maybe I should run them to a separate location. a new universal ground terminal strip I can run from the battery and put all factory wiring back with no aftermarket devices stacks on the bolt

What year is your truck? How old is your battery? Some of these may be low voltage issues.
