2015 Prius Plug-in ECU Skid Control Failure

Hi Everyone --

I wanted to see if anyone has experienced any of the same issues and/or could provide professional advice.

I had a collision that impacted the front passenger side tire and front suspension. That same night, it was raining and when I was driving home -- the VSC light came on. The car was towed to the shop for repairs. After I picked it up from the shop and started driving it, the parking brake light and ABS lights came on. I took it back to the shop to look at it again, since they did replace the ABS sensor on the right side -- but they could not figure it out.

Took it to Toyota for diagnostic -- they couldn't figure it out either, they had to call the techline which then suggested replacing the ECU skid control unit. Insurance denied this part of the claim as it just said internal failure/malfunction and there wasn't anything linking the two. Toyota quoted me $2533 for the Ecu replacement part and $1134 for labor, $3667 total that would be out of my pocket!! I am holding off in taking any action, the car drives normal right now.

Codes: C1231, C1345, C1368, C1451

Any suggestions or advice??

Thank you!
