DTC C124F-62: Yaw Rate Sensor Signal Compare Failure [12/2019 - 11/2023]: Procedure

1. Perform a road test.
2. Check the yaw rate sensor output value displayed on the GTS.

   Chassis > Brake/EPB > Data List 

   Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
   Yaw Rate Sensor Value	Yaw rate sensor	Min.: -128°/s Max.: 127°/s	Vehicle stopped: 0°/s Turning right: -128 to 0°/s Turning left: 0 to 127°/s	-

   Chassis > Brake/EPB > Data List 

   Tester Display
   Yaw Rate Sensor Value

   Result

   Result	Proceed to
   NG (The yaw rate sensor output value is 0°/s when the vehicle is stationary, but the value fluctuates when turning.)	A
   NG (The yaw rate sensor output value is not 0°/s when the vehicle is stationary.)	B
   OK	C

Result: 

B
