DTC U0123-00  : Yaw Rate Sensor Circuit Error

NOTE: 

  • Before you troubleshoot, review the general troubleshooting information .
  • This vehicle's multipurpose camera unit receives the failure information of the yaw rate sensor from the SRS unit. The SRS unit does not uses the yaw rate sensor for airbag deployment control, so the SRS system indicator does not come on even if the yaw rate sensor is faulty. If this DTD is stored, clear the DTC and then perform problem verification according to the troubleshooting flow. If this DTC is stored again, replace the SRS unit.
  • If DTC U0151-00 is stored at the same time as DTC U0123-00, troubleshoot DTC U0151-00 first, then recheck for DTC U0123-00.
