2005 prius wont engage drive... abs related issue

I replaced my hybrid battery with one I bought off ebay for $1000 installed. Now when trying to start the car again for the first time with new battery, it will not start all the way and go into gear. it begins to fire-up then just doesn't. it flashes ready 4 times then when usually the speedometer would throw up a zero, there is nothing. the codes I got were c1241 c1259 c1310 c1378 the abs icon is displayed with every code. I erased these then ran again and still had the actuator code. Does this mean that I need to replace the actuator or is there maintenance that can suffice? or do you think its something dif all together and it should start with that code?
I have been getting a beeping noise when I touch the brake pedal for a while now. it goes off after the car fully turns on..

 

Yes I hear the 3 clicks. And have the plug down. The accumulator pump malfunction code is still there so I don't think my brakes are working properly. How should I trouble shoot the brakes? And could that keep the car from starting?

 

I just bought and installed a brand new prius 12 volt optimo battery today, to be sure that wasn't the issue, plus I don't have another vehicle and need to get to work at 5:00 a.m evry morning :/
I am using an innova scanner model 3030 f. 100$ From Walmart. I erased all the existing codes (using the scanner). When I re-started the car I didn't even touch the brake peddal. The only codes I got were c1259 (hv system regenerative malfunction) and c1310 (malfunction in hv system). I'm still having exact same problem

 

Ok thank you. Where can I get a mini Vci?

 

Is there anywhere I can buy a mini Vci today? In phoenix

 

My hybrid battery went out in July and literally blew up a cell. I started taking it apart to replace the cells myself but got in a little over my head and just bought one off eBay and had it installed by the technician there brought it to me. After practicing on my first battery I knew my way around them a bit and since then have replaced cells for a few other and all were successful. Now the one I bought and had professionally installed by "high voltage solutionz" has gone bad. They said they would replace it for free but the tech wouldn't get to me for a week. After speaking with the tech personally one week turned into three weeks and now we're going onto five weeks but in the meantime he has sent me two good cells which I installed myself a few days ago. Now over the phone that tech has instructed me to buy that OB D2 scanner and now is telling me that the inverter is the problem and that's why my battery was dropping cells. I found a used inverter here for $200 with a 30 day moneyback gaurauntee. I'm going to swap them tonight.

 

Lol yeah if it gets fixed within the next day or two I will still think it's worth it to have the prius. Love this car (except for this prob)

 

Anyone know of a good step by step Set of instructions for swapping a gen 2 prius hybrid dc/dc inverter?

 

Thank you that selidori link is great. How can I get book 22 so I can figure out how to drain my fluid?
