Yaw rate sensor zero point calibration is unfinished

What is your question?

Yaw rate and acceleration sensor zero point calibration is unfinished. Zero Point Calibration undone. Skid Control ECU. Abs light on since I bought the car it’s already been 2 years since that. First problem I have had that i have been told to go to Toyota for assistance. Any advice that I could try before my appointment with Toyota.
