Climate Control doesn't work, Flooded with B1 Error Codes
So I've been trying to figure out why my climate control doesn't work anymore.
I went to troubleshoot it, and got a ton of codes
A month ago, it started puffing out white smoke and it had a faint smell of something burnt, but still worked.
Then a few days later, it would only stay on for a brief moment then turn off. I'd have to turn off/on AC to restart it, but then it would do it again.
Now, it just doesn't turn on at all. None what-so-ever.
I'm pretty dumbfounded.
Honestly I don't know where to begin with trying to fix it, was hoping to get some insight here.
Please and thank you.

I just bounced over here from the 240 forum,and don't know anything about 850's.However from my diesel tech. experience,when there are many codes,it usually is caused by a power supply interruption issue to, or within the ECU or controller. When the power is interrupted,the data (sensor return voltage),and update rates are erratic,thus setting multiple codes.
