Limp Home mode on Volvo 680

Does anyone know what this means? it all started after I had to stop before the RR tracks (hazmat load) on a sheet of ice. I was not gaining any traction afterwards given it all happened on 3” of ice covered road just outside Olivia, Minnesota US-71.
I have a Volvo 680 and the company shop told me I can’t drive nor get the problem fixed soon. Glad there’s a couple trucks stops I was able to crawl to.
In other words: Am I screwed?

 

I don’t have any leaks, pressure shows 120 psi on the dash which is normal. I’m trying to look what the problem is but nothing visible.
Given Volvo’s reputation: is this an electrical problem?

 

Yes they are. Tandems and drives.

 

Thanks!

 

Oooh let me try this. One sec
