DTC C124F-62: Yaw Rate Sensor Signal Compare Failure [11/2021 - 10/2023]: 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 

REPLACE AIRBAG ECU ASSEMBLY. Refer to  REMOVAL [11/2021 - 10/2022]  , or refer to  REMOVAL [10/2022 - 10/2023] 

Result: 

C 

USE SIMULATION METHOD TO CHECK. Refer to  HOW TO PROCEED WITH TROUBLESHOOTING [11/2021 - 10/2022]  , or refer to  HOW TO PROCEED WITH TROUBLESHOOTING [10/2022 - 10/2023] 

Result: 

A 

See step  2

1. Turn the ignition switch off.
2. Check that the yaw rate sensor (airbag ECU assembly) has been installed properly.

   Refer to INSTALLATION [11/2021 - 10/2023]

   OK

   The yaw rate sensor (airbag ECU assembly) is tightened to the specified torque.

   The yaw rate sensor (airbag ECU assembly) is not installed in a tilted position.

   Result

   Proceed to
   OK
   NG

Result: 

OK 

REPLACE AIRBAG ECU ASSEMBLY. Refer to  REMOVAL [11/2021 - 10/2022]  , or refer to  REMOVAL [10/2022 - 10/2023] 

Result: 

NG 

INSTALL AIRBAG ECU ASSEMBLY. Refer to  INSTALLATION [11/2021 - 10/2023]
