Code C1AA5 2014 Toyota RAV4 Description

For vehicles with Lane Departure Alert System: The Yaw Rate Sensor is integrated with Airbag Sensor Assembly. the Skid Control ECU (Brake Actuator Assembly) sends the vehicle stability signals to the Lane Departure Warning Camera. If the Skid Control ECU (Brake Actuator Assembly) detects that the Yaw Rate Sensor is malfunctioning, the Skid Control ECU (Brake Actuator Assembly) sends a malfunction signal to the Lane Departure Warning Camera via the Controller Area Network (CAN) communication, and the Lane Departure Warning Camera stores Diagnostic Trouble Code (DTC) C1AA4, C1AA5 or C1AA6.

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.
