Tech Tips


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

  • When a speed sensor, or the yaw rate 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 sensor (airbag sensor assembly) are output together with DTCs for the steering angle sensor, inspect and repair the speed sensor or yaw rate sensor (airbag sensor assembly) first, and then inspect and repair the steering angle sensor (for optitron meter type).

    When a speed sensor, or the yaw rate and acceleration sensor 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 are output together with DTCs for the steering angle sensor, inspect and repair the speed sensor or yaw rate and acceleration sensor first, and then inspect and repair the steering angle sensor (for TFT meter type).
