Help/Advice with Yaris Cross PCA/LTA Malfunction 'C05261C'

[MrEthical12]

Hi there folks, hope you’re all doing well.

I had a minor collision a few months ago with my Yaris Cross on the passenger side, and I’ve since had it repaired. The damage was mainly to the bumper, headlight, and the wishbone on the passenger side. All of those parts have been replaced, and the car’s been aligned. However, since the repairs, I’ve been dealing with a Pre-collision malfunction, LTA malfunction, and a brake hold malfunction.

I’ve got access to Techstream V18 and managed to pull up some codes related to the Brake System / Front Radar Sensors. The codes I’m getting are U012987 and C05261C. One thing that stood out to me is an issue with the steering angle sensor. The data list shows 0 degrees for the steering angle point, but the brake system data shows a steering angle of 33 degrees. I’ve tried clearing the DTC codes and resetting the memory before performing a zero-point calibration, but every time I drive above 20 km/h, the errors reappear and stay until I clear them again.

I’ve gone through and checked every fuse in the vehicle, and everything seems to be in order. The wiring harnesses look fine as well—no visible signs of damage. Since I only replaced the wishbone on the side of the impact and not the track rod end or hub, I’m wondering if that might be part of the issue. But no matter what I do, the error codes keep coming back.

I’m attaching some images from Techstream to give a better picture of what’s going on. Any help or advice would be really appreciated—thanks in advance!
