Lights won't turn off!

I had this happen in my cascadia try turning off your batteries for 30 mins. If you don't have a switch you'll need to unhook the cables. I latter was told this was caused by me not letting the truck completely boot up before starting,meaning I wasn't waiting for the gauges cycle before I turned the key all the way

 

Yeah the tech that told me said it's like your laptop starting without all the files loading. This was on a 2011 cascadia, not letting boot all the way can also start causing a lot of dash codes too

 

Not sure of your make of truck,but on a 2009 cascadia when I had that problem ..it was due to windshield leaking behind panels onto a cab ecm that caused that ...there are something like 7or8 computers on a cascadia

 

Anybody else think it's asinine to have the lights hooked in with the computer

 

Take it to a mechanic so he can see what year, make, model truck you have, we can't see it from here so you'll have to tell us if you want real help.

 

A simple wiring and toggle switches works for me. But hey, let's make things more complicated

 

Yes, it is Volvo. If light switch goes bad, LCM turns on light! Pull LCM codes!!!
