Code C1AA5 2015 Toyota RAV4 Description
For vehicles with Forward Recognition Camera System: The Forward Recognition Camera receives vehicle stability signals from the Yaw Rate Sensor Assembly. If the Yaw Rate Sensor Assembly detects an abnormal Yaw Rate Sensor signal or Yaw Rate Sensor Assembly power supply voltage, it informs the Forward Recognition Camera via CAN communication, and DTC C1AA4 or C1AA5 is stored.
For vehicles with Lane Departure Alert System (W/ Steering Control): The Forward Recognition Camera receives vehicle stability signals from the Yaw Rate Sensor Assembly. If the Yaw Rate Sensor Assembly detects an abnormal Yaw Rate Sensor signal or Yaw Rate Sensor Assembly power supply voltage, it informs the Forward Recognition Camera via CAN communication, and DTC C1AA4 or C1AA5 is stored.
What are the Possible Causes of the DTC C1AA5 2015 Toyota RAV4?
- Faulty Vehicle Stability Control System
- Faulty Yaw Rate and Acceleration Sensor (Airbag Sensor Assembly) (For Forward Recognition Camera System)
- Faulty Forward Recognition Camera (For vehicles with Forward Recognition Camera System)
- Faulty Lane Departure Warning Camera (For vehicles with Lane Departure Alert System)
