HINT:

When U0126/63 is output together with C1231/31, inspect and repair the trouble areas indicated by U0126/63 first.
Refer to DTC U0073/94: Control Module Communication Bus OFF; DTC U0120/96: Lost Communication with Starter / Generator Control Module; DTC U0123/62: Lost Communication with Yaw Rate Sensor Module; DTC U0124/95: Lost Communication with Lateral Acceleration Sensor Module; DTC U0126/63: Lost Communication with Steering Angle Sensor Module; DTC U0293/59: Communication Error from HV ECU [06/2015 - ]
When a speed sensor or yaw rate and acceleration sensor (airbag ECU assembly) is malfunctioning, DTCs for the steering sensor may be output even when the steering sensor is normal. When DTCs for a speed sensor or the yaw rate and acceleration sensor (airbag ECU assembly) are output together with DTCs for the steering sensor inspect and repair the speed sensor and yaw rate and acceleration sensor (airbag ECU assembly) first, and then inspect and repair the steering sensor.
