DTC C1434: Steering Angle Sensor Output Malfunction [08/2019 - ]: Procedure

1. Clear the DTCs (Refer to DTC CHECK / CLEAR [08/2019 - ] ).
2. Turn the ignition switch off.
3. Turn the ignition switch to ON again and check that no CAN communication system DTC is output (Refer to DIAGNOSIS SYSTEM [08/2019 - 08/2021] , or refer to DIAGNOSIS SYSTEM [08/2021 - 08/2022] , or refer to DIAGNOSIS SYSTEM [08/2022 - ] ).
4. Start the engine.
5. Drive the vehicle at a speed of 35 km/h (22 mph) and turn the steering wheel to the right and left, and then check that no speed sensor or yaw rate and acceleration sensor DTCs are output (Refer to DTC CHECK / CLEAR [08/2019 - ] ).
   RESULT
   
   

   Result	Proceed to
   No CAN communication system, speed sensor, or yaw rate and acceleration sensor DTCs are output	A
   CAN communication system DTC is output	B
   Speed sensor or yaw rate and acceleration sensor DTC is output	C

   HINT: 

   • If there is a malfunction in any of the speed sensors or the yaw rate and acceleration sensor (air bag sensor assembly), an abnormal value may be output although the steering angle sensor is normal.
   • If speed sensor and yaw rate and acceleration sensor DTCs are output simultaneously, repair these two sensors first, and then inspect the steering angle sensor.
