DTC C1436: Malfunction in Yaw Rate Sensor [04/2018 - ]: Procedure
- READ VALUE USING TECHSTREAM (YAW RATE SENSOR)
- Select the Data List on the Techstream.
Refer to DATA LIST / ACTIVE TEST [04/2018 - ]
Chassis > ABS/VSC/TRAC > Data List
Tester Display Measurement Item Range Normal Condition Diagnostic Note Yaw Rate Sensor Yaw rate sensor 1 Min.: -128 degrees/s, Max.: 127 degrees/s Vehicle stationary: 0 degrees/s
Turning right: -128 to 0 degrees/s
Turning left: 0 to 127 degrees/s- Yaw Rate Sensor2 Yaw rate sensor 2 Min.: -128 degrees/s, Max.: 127 degrees/s Vehicle stationary: 0 degrees/s
Turning right: -128 to 0 degrees/s
Turning left: 0 to 127 degrees/s- Chassis > ABS/VSC/TRAC > Data List
Tester Display Yaw Rate Sensor Yaw Rate Sensor2 - Check the yaw rate sensor output value displayed on the Techstream.
Result
Result Proceed to NG (The yaw rate sensor (airbag ECU assembly) output value is 0 deg/s when the vehicle is stationary, but the value fluctuates when turning.) A NG (The yaw rate sensor (airbag ECU assembly) output value is not 0 deg/s when the vehicle is stationary.) B OK C
Result:
B
REPLACE AIRBAG ECU ASSEMBLY. Refer to REMOVAL [04/2018 - 08/2020] , or refer to REMOVAL [08/2020 - 08/2021] , or refer to REMOVAL [08/2021 - ]
Result:
C
USE SIMULATION METHOD TO CHECK. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [04/2018 - ]
Result:
A
See step 2
- Select the Data List on the Techstream.
- CHECK AIRBAG ECU ASSEMBLY INSTALLATION
- Turn the power switch off.
- Check that the yaw rate and acceleration sensor (airbag ECU assembly) has been installed properly.
Refer to INSTALLATION [04/2018 - 08/2020] , or refer to INSTALLATION [08/2020 - ]
OK
The yaw rate and acceleration sensor (airbag ECU assembly) is tightened to the specified torque.
The yaw rate and acceleration sensor (airbag ECU assembly) is not tilted.
Result
Proceed to OK NG
Result:
OK
REPLACE AIRBAG ECU ASSEMBLY. Refer to REMOVAL [04/2018 - 08/2020] , or refer to REMOVAL [08/2020 - 08/2021] , or refer to REMOVAL [08/2021 - ]
Result:
NG
INSTALL AIRBAG ECU ASSEMBLY CORRECTLY. Refer to INSTALLATION [04/2018 - 08/2020] , or refer to INSTALLATION [08/2020 - ]
