sos ...Is this car serviceable?

I'm being told I don't have permission to view that.

 

C1259 and C1310 just mean "hey, there are power management control ECU codes, go look there", so that's all about the P0A94.

C1241 is weird (usually weird low) voltage arriving at the brake system. It can be because of low voltage on the 12 volt aux battery (but can also be other things, like problems in the wiring on the way from the battery to the brake system).

But here we've got a P0A94, which is a problem with the system that charges the 12 volt battery, so there's a pretty good reason to think that battery could have low charge.

The C1241 should have a "freeze frame" that shows what some key voltages were at the time the code was set. It could also be worth just going and measuring what voltage is on the 12 volt battery now.

Don't clear the P0A94 code; it might qualify you for a free converter replacement. I've forgotten what the time/mile limits are on that for a v.
