2010 TOYOTA TUNDRA with 29000.0 miles

My vehicle began to display the vsc (vehicle stability control) light, constantly on, last week when i turned it on. Several days later the brake light and abs light also became constantly on. I decided to take it to the nearest Toyota dealer and they stated that the vehicle is giving the following codes: C1203 - ecm communication circuit C1232 - deceleration sensor C1336 - zero point calibration of deceleration sensor undone the service manager told me that they were going to try to re-flash the computer and calibrate affected items but if it wasn't possible that the sensor assembly, yaw sensor was bad and needed replacement, totaling $1305. 2 hours later he called me back to tell me that they couldn't re-flash the computer and that the issue is not the sensor assembly, yaw sensor but the abs actuator assembly, totaling over $2700. I'm reporting this since i've seen a bunch of similar cases but nothing concrete from Toyota. I really don't know if this issue is un-safe or not since there are no physical symptoms except not having abs nor traction control.

2008 TOYOTA TUNDRA with 109000. miles

The brake pedal feels "soft" when applying the brakes. Pedal travels farther than usual, must step down hard for brakes to fully engage - no air in brake lines - brake fluid reservoir is full - all brake pads/shoes w/90% life remaining. C1336 code keeps coming up referring to "zero point" calibration, and abs pump. Condition is present during all types of driving - city - highway - turning - backing. Symptoms started in early september 2017.
