   Vehicle Speed

   Result

   Result	Proceed to
   The value of Vehicle speed is 0 km/h (0 mph) and the value of Lateral G is less than -7 m/s2 or more than 7 m/s2 .	A
   Other than above.	B

Result: 

A 

REPLACE AIRBAG SENSOR ASSEMBLY. Refer to  REMOVAL [10/2020 - ] 

Result: 

B 

See step  3

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

   Refer to INSTALLATION [03/2020 - ]

   OK

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

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

   Result

   Proceed to
   OK
   NG

Result: 

OK 

REPLACE AIRBAG SENSOR ASSEMBLY. Refer to  REMOVAL [10/2020 - ] 

Result: 

NG 

INSTALL AIRBAG SENSOR ASSEMBLY CORRECTLY. Refer to  INSTALLATION [03/2020 - ]
