Code C1A10 2014 Toyota RAV4 Description
For vehicles with Forward Recognition Camera System: The Forward Recognition Camera uses the Millimeter Wave Radar Sensor Assembly to detect obstacles in front of the vehicle. When the Forward Recognition Camera receives information that there is a malfunction in the Millimeter Wave Radar Sensor Assembly, DTC C1A10 is stored.
For vehicles with Lane Departure Alert System (W/ Steering Control): The Lane departure alert system (Forward Recognition Camera) uses the Millimeter Wave Radar Sensor Assembly to detect obstacles in front of the vehicle. When the Forward Recognition Camera receives information that there is a malfunction in the Millimeter Wave Radar Sensor Assembly, DTC C1A10 is stored.
For vehicles with Pre-collision System: The Driving Support ECU Assembly uses the Millimeter Wave Radar Sensor Assembly to detect obstacles in front of the vehicle. Based on these signals from the Millimeter Wave Radar Sensor Assembly, the Driving Support ECU Assembly sends pre-collision control operation signals. When the Driving Support ECU Assembly receives an internal malfunction signal from the Millimeter Wave Radar Sensor Assembly, DTC C1A10 is stored.
