2017 Volvo VNL Interior Power Problem

Good morning everyone!

I have a 2017 Volvo VNL 780 with a very odd problem. The truck sat for a month or so while we were waiting for the camshaft to show up. (later model 2017 with the fake CR engine, spun a lobe)

The truck's interior lights are not turning on, they are flashing on-off instead. Dash works fine. 12V outlets are not working, none of them including the ones in the bunk. The fridge is not getting power either.

We checked all the fuses and the relays. Swapped relays, still nothing.

What are your thoughts? @nasriza , maybe you have an idea on this?

Thank you all!

 

Hey Nas! That’s exactly what we are doing this Sunday when they come back. Pretty sure the low voltage disconnect is the issue. Either not plugged in or missing the connection.

By now, the LVD would reset itself since it saw enough voltage from the battery.

Thank you for the feedback brother. As always!
