Yaw Rate Sensor Wrong Installation (X0456) [11/2021 - ]: Procedure

1. Perform the Health Check using the GTS.

   Result

   Result	Proceed to
   DTCs are not output	A
   DTCs are output	B

Result: 

B 

GO TO DIAGNOSTIC TROUBLE CODE CHART. Refer To  DIAGNOSTIC TROUBLE CODE CHART [11/2021 - ] 

Result: 

A 

See step  2

1. Check Data List item "yaw rate sensor value".

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

Result: 

B 

REPLACE AIRBAG SENSOR ASSEMBLY. Refer to  REMOVAL [11/2021 - 03/2024]  , or refer to  REMOVAL [03/2024 - ] 

Result: 

C 

USE SIMULATION METHOD TO CHECK. Refer to  HOW TO PROCEED WITH TROUBLESHOOTING [11/2021 - ] 

Result: 

A 

See step  3

1. Check that the yaw rate and acceleration sensor (airbag sensor assembly) has been installed properly.

   Refer to INSTALLATION [11/2021 - 03/2024] , or refer to INSTALLATION [03/2024 - ]

   OK

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

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

   Result

   Proceed to
   OK
   NG

Result: 

NG 

INSTALL AIRBAG SENSOR ASSEMBLY. Refer to  INSTALLATION [11/2021 - 03/2024]  , or refer to  INSTALLATION [03/2024 - ] 

Result: 

OK 

See step  4

1. Using the GTS, clear the Vehicle Control History (RoB).

   Chassis > Brake/EPB > Utility 

   Tester Display
   Vehicle Control History (RoB)

   Result

   Proceed to
   NEXT

Result: 

NEXT 

See step  5

1. Drive the vehicle straight ahead at 35 km/h (22 mph) or more for at least 5 seconds.
