Definition:
Yaw Rate Circuit
Description:
Ignition ON.
Cause:
Vehicle speed has reached at least 15 km or h (9 mph) from a stop more three times during the same ignition cycle.During the time the vehicle is stationary;the yaw rate signal value is more than 7 deg or sec for 2 seconds.When vehicle speed is more than 25 km or h (16 mph) in a turn the difference between the yaw rate,steering angle,lateral acceleration,and wheel speed sensor values are not correlated three consecutive times.Yaw rate changes greater than 20 deg or sec in 6 ms four times in one second.Combination sensor fails an internal self test.Ignition voltage to the combination sensor is less than 9.5 volts.Communication is lost between the EBCM and the combination sensor.
