Dear Scotty,
Greetings from the heat of Arizona. I have a 2006 Prius with 91,355 miles and with an automatic transmission. It currently has codes C1310, P3107, and B1610. It also displays the word problem on the trip display screen. On the combination meeter, the big red triangle of death is also displayed. I did clear the codes and they came right back.

Dear scotty and members,
I wanted to give an update on this topic. It has been a year since I posted this question and I wanted to give an update in regards to this and what came to a conclusion to fixing the problem.
These are the codes I will be focusing On the first part P3107, C1310, B1610
in the first part. the codes of P3107 which is lost communication with airbag system control module and C1310 is hv system hault . These are triggered by the code of B1610 which is front right airbag sensor. The C1310 comes since the. hv system is tapped into the airbag system. I spent countless hours/breaking my head trying to figure out why theae codes would come one and which of them caused to trip their little friends. I finally found a form online and it was in Russian thanks to good old Google for translating. Someone had the same issue and mention where the front right airbag sensor is it has two wires black and white. They listed a wire diagram and the wires led to a bundle of wires underneath the headlight and found spit wires. So I decided what the heck at this point who knows if this will even work. And sure enough I found the harness and behold!!! Seems someone was there before and let's just say they didn't do a well job. Fixed them properly and triangle of death turned off so did the airbag and the little "problem" displayed on the display screen. I can finally use my cruise control.
Now for the code B1248 which is AVC LAN communication. Looked into code and fixed it by mistake while working on the B1610 code. I took the entire dash apart and found on the inside drivers side. There is a conjunction box and behind it had a yellow wire that was just hanging out there and chilling. It also had a red or pink wire, brown wire. That code went away when replacing that connector with another one with the same color wires and connector. I'll see if I can find the paper I printer from alldata which didn't help that well explaining the locations of these connectors and diagrams.
So, I hope anyone in this group has a similar what I had and will find this helpful.
thank you for posting the solution
Those codes suggest a problem in the hybrid control system or ECU. (The last two are airbag communications codes that may be triggered by the C1310.) You're probably going to need a mechanic experienced in hybrid systems to sort this out.
There is a video out there claiming an "easy fix" for C1310 but that's due to water intrusion through the rear hatch which seems unlikely in Arizona.

Thank you! A new hybrid battery was installed a month ago. It ran perfectly fine after installation. it even passed emissions. This happened after changing the oil. I placed the care in maintenance mode to check the oil and that's when the issues occurred. could be possible that the airbag codes are causing the C1310. Yeah, I checked the normal 12v battery. For some reason, a lot of people are saying water gets there why is knows.
I don't know enough about hybrids to say but it seems that some latent issue having to do with installation of the new battery would be more likely to trigger the C1310 than airbag issues. I was thinking that they all may point to some wiring or grounding problem. Or, maybe the hybrid ECU has decided to go out on you. Like I said I think you're going to need someone experienced in hybrid electrical systems for this one. Maybe one of the other guys or @scottykilmer would have some ideas.
Thank you. I made sure when the battery was installed all cables were connected properly, and no grounds or connections were missing. I took many pictures and marked where everything goes. We may need the godfather scottykilmer on this one. I check the connections to the HV ECU and everything was okay. I disconnected everything to see any damaged wires and everything was good. It ran pretty really well after installation for a month. I drove it all over town and drove really well. I remember in school. Sometimes when one thing goes bad it can throw other codes and at times are connected together. I really appreciate the help.
@scottykilmer any recommendations or suggestions?
