HINT:

When U0073, U0123 and/or U0126 is output together with C1434, inspect and repair the trouble areas indicated by U0073, U0123 and/or U0126 first.
Refer to DTC U0073: Control Module Communication Bus OFF; DTC U0100: Lost Communication with ECM / PCM; DTC U0123: Lost Communication with Yaw Rate Sensor Module; DTC U0126: Lost Communication with Steering Angle Sensor Module; DTC U0151: Lost Communication with Airbag ECU [06/2017 - 10/2020]
When a speed sensor or the yaw rate and acceleration sensor (airbag sensor assembly) is malfunctioning, DTCs for the steering angle sensor may be stored even though the steering angle sensor is normal. When DTCs for a speed sensor or yaw rate and acceleration sensor (airbag sensor assembly) are output together with DTCs for the steering angle sensor, inspect and repair the speed sensor or yaw rate and acceleration sensor (airbag sensor assembly) first, and then inspect and repair the steering angle sensor.
