Yaw Rate Sensor Signal Bias Level Out of Range / Zero Adjustment Failure

With the vehicle stationary, the yaw rate sensor output value is not 0°/s.
  • Yaw rate sensor (airbag sensor assembly) (for Optitron Meter Type)
  • Yaw rate sensor (yaw rate and acceleration sensor) (for TFT Meter Type)

C006396

Yaw Rate Sensor Component Internal Failure

With the +BS terminal voltage between 9.5 and 17.4 V, a data malfunction signal is received from a yaw rate sensor.
  • Yaw rate sensor (airbag sensor assembly) (for Optitron Meter Type)
  • Yaw rate sensor (yaw rate and acceleration sensor) (for TFT Meter Type)

CAUTION / NOTICE / HINT

NOTICE:

If the yaw rate and acceleration sensor (airbag sensor assembly) was replaced or reinstalled, perform "Calibration". (for Optitron Meter Type)

If the yaw rate and acceleration sensor was replaced or reinstalled, perform "Calibration". (for TFT Meter Type)
