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.
