DTC C1436: Yaw Rate Sensor Malfunction [06/2017 - 10/2020]: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Enter the following menus: Chassis / ABS/VSC/TRAC/EPB / Data List.

   Chassis > ABS/VSC/TRAC/EPB > Data List 

   Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
   Yaw Rate Sensor	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 > ABS/VSC/TRAC/EPB > Data List 

   Tester Display
   Yaw Rate Sensor

4. Check the yaw rate and acceleration sensor (airbag sensor assembly) output value displayed on the Techstream.

   Result

   Result	Proceed to
   The value of Yaw Rate Sensor is 0°/s when the vehicle is stopped and the output value fluctuate when the vehicle turning right or left	A
   The value of Yaw Rate Sensor is not 0°/s when the vehicle is stopped	B
   The value of Yaw Rate Sensor is 0°/s when the vehicle is stopped and the output value does not fluctuate when the vehicle turning right or left	C

Result: 

B 

REPLACE AIRBAG SENSOR ASSEMBLY. Refer to  REMOVAL [06/2017 - 09/2019]  , or refer to  REMOVAL [09/2019 - 03/2020]  , or refer to  REMOVAL [03/2020 - 10/2020] 

Result: 

C 

USE SIMULATION METHOD TO CHECK. Refer to  HOW TO PROCEED WITH TROUBLESHOOTING [06/2017 - 08/2018]  , or refer to  HOW TO PROCEED WITH TROUBLESHOOTING [08/2018 - 09/2019]  , or refer to  HOW TO PROCEED WITH TROUBLESHOOTING [09/2019 - 03/2020]  , or refer to  HOW TO PROCEED WITH TROUBLESHOOTING [03/2020 - 10/2020] 

Result: 

A 

See step  2

1. Turn the ignition switch off.
2. Drive the vehicle straight ahead at 15 km/h (9 mph) or more for at least 1 second.
3. Check that the steering wheel is correctly centered while driving straight ahead.

   HINT: 

   If front wheel alignment and steering are adjusted as a result of an off-center steering wheel, acquire the yaw rate and acceleration sensor zero point again after the adjustments are completed.

   OK

   The steering wheel is correctly centered.

   Result

   Proceed to
   OK
   NG

Result: 

NG 

ADJUST FRONT WHEEL ALIGNMENT OR STEERING. Refer to  ADJUSTMENT [06/2017 - 08/2018]  , or refer to  ADJUSTMENT [08/2018 - 09/2019]  , or refer to  ADJUSTMENT [09/2019 - 03/2020]  , or refer to  ADJUSTMENT [03/2020 - 10/2020] 

Result: 

OK 

See step  3

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

   Refer to INSTALLATION [06/2017 - 09/2019] , or refer to INSTALLATION [09/2019 - 03/2020] , or 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 [06/2017 - 09/2019]  , or refer to  REMOVAL [09/2019 - 03/2020]  , or refer to  REMOVAL [03/2020 - 10/2020] 

Result: 

NG 

INSTALL AIRBAG SENSOR ASSEMBLY CORRECTLY. Refer to  INSTALLATION [06/2017 - 09/2019]  , or refer to  INSTALLATION [09/2019 - 03/2020]  , or refer to  INSTALLATION [03/2020 - ]
