Tech Tips


  • When DTC U0073, U0123, U0124 and/or U0126 is output together with DTC C1433, inspect and repair the trouble areas indicated by DTC U0073, U0123, U0124 and/or U0126 first Click here.

  • When any of the speed sensors or the yaw rate and acceleration sensor has trouble, DTCs for the steering angle sensor may be stored even when the steering angle sensor is normal. When DTCs for the speed sensors or yaw rate and acceleration sensor are output together with DTCs for the steering angle sensor, inspect and repair the speed sensor and yaw rate and acceleration sensor first, and then inspect and repair the steering angle sensor.
