Code C1AA6 Lexus Description
For vehicles with Forward Recognition Camera System: The Skid Control ECU (Brake Actuator Assembly) receives vehicle stability signals from the Yaw Rate Sensor. If the Skid Control ECU (Brake Actuator Assembly) detects a Yaw Rate Sensor zero-point malfunction signal, it informs the forward recognition camera via CAN communication, and DTC C1AA6 is stored.
For vehicles with Lane Departure Alert System (W/ Steering Control): The Skid Control ECU (Brake Actuator Assembly) receives vehicle stability signals from the Yaw Rate Sensor. If the Skid Control ECU (Brake Actuator Assembly) detects a Yaw Rate Sensor zero-point malfunction signal, it informs the forward recognition camera via CAN communication, and DTC C1AA6 is stored.
What are the Possible Causes of the DTC C1AA6 Lexus?
- 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)
