What type of wheels were installed and are they the same size as the OEM wheels?
The code you are getting is related to the YAW system. I will try to explain it. The Yaw rate sensor measures the car's rotation rate. Basically, the sensor determines how far off-axis a car is tilting in a turn. This information is then fed into a microcomputer that compares the data with wheel speed, steering angle and accelerator position. If the system senses too much yaw, braking force is applied. Lastly, the wheel speed sensors measures the wheel speed. If there is a change there (difference in wheel size) the stabilitrac system will malfunction and the ABS will stop working. The entire car is being monitored. Basically, steering, speed, stopping, the vehicle's axis is monitored, and everything comes together to determine if the computer needs to compensate for driver error. I hope this helps and doesn't add further confusion in your life.
As far as the parts they want to replace, I would have to question why they were fine prior to the new wheels.
