CAUTION / NOTICE / HINT

Note

Inspect the fuses for circuits related to this system before performing the following inspection procedure.

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 Click here.

  • When any of the speed sensors or the airbag sensor assembly (yaw rate sensor) has trouble, DTCs for the spiral cable sub-assembly (steering sensor) may be output even when the spiral cable sub-assembly (steering sensor) is normal. When DTCs for the speed sensors or airbag sensor assembly (yaw rate sensor) are output together with DTCs for the spiral cable sub-assembly (steering sensor), inspect and repair the speed sensor and airbag sensor assembly (yaw rate sensor) first, and then inspect and repair the spiral cable sub-assembly (steering sensor).
