Onboard Computer/Systems going crazy !?

[Kbm]

So, since yesterday my car/computer is going berserk on me, alerts goes on and off (mostly on) with the following warnings:

TPMS
ABS / BRAKES
DSC / Traction Control
Cruise Control

... and off course, all those lights are amber on my dash (kind look cute, it is like a xmas three off season ! :lol and none of these work anymore... in addition to the turning signal that now also don't turn off after a curve, I have to hit it again to turn off.

For the record, the radio still works ! :happyanim:

I'll bring it to some shop this weekend to get it checked, but if someone has any idea what the heck is going on please share
