Variation of the yaw rate value from the combined sensor while the vehicle is
stopped or started is not within the specification.
Condition 1
The difference between the yaw rate value calculated by each
sensor and the yaw rate value from the combined sensor exceeds
the specification.
Condition 2
While the vehicle is moving forward, one of the yaw rate values is
+ and the other is - (yaw rate value calculated from steering
angle sensor signal and one from the combined sensor).
Difference between the two lateral-G values exceeds the specification (one from
the combined sensor and one calculated from yaw rate signal from the combined
sensor, steering angle sensor signal, and ABS wheel-speed sensor signal).
Signal, which indicates low voltage or over voltage, from the combined sensor is
continued for 100 ms.
Variation of the lateral-G value from the combined sensor is not within the
specification.
Inhibits TCS control and DSC control, and illuminates DSC indicator light.
(If error is detected during a TCS control, inhibits TCS control after finishing the
control.)
