Default Error codes: C1252, C1256, C1300

2006 Toyota Prius with 308,000 miles (body) engine replaced at 256,000 with one that had 56k. Has been sitting about a year because the hybrid battery needed to be replaced. Replaced it a few days ago and now these codes came up when the guy changed it. I looked up C1256, and from my finding it looks like it is the accumulator pump- is this correct? Couldnt find any info on the other codes. I donít really wanna get rid of the car because itís in good shape, no major body damage, inside is in good condition. When the breaks went out last year thatís when I found out the hybrid battery also needed to be replaced. Toyota didnít know why the breaks went out and sent me on my way. Any recommendations? Hereís a pic of the codes from the guys computer.

The 12 V battery is probably dead (or very weak) from just sitting for a year.
