Code C1A14 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 vehicle is determined to be driving in a straight line or on a gradual curve based on signals from the yaw rate sensor etc., the Millimeter Wave Radar Sensor Assembly performs self-diagnosis to check if the sensor beam axis has deviated from the vehicle movement direction. When the Millimeter Wave Radar Sensor Assembly beam axis has deviated, the Forward Recognition Camera detects this, and stores DTC C1A11. After installing a new Millimeter Wave Radar Sensor Assembly, if sensor beam axis adjustment is not performed, DTC C1A14 is stored.
For vehicles with Lane Departure Alert System (W/ Steering Control): The Forward Recognition Camera uses the Millimeter Wave Radar Sensor Assembly to detect obstacles in front of the vehicle. When the vehicle is determined to be driving in a straight line or on a gradual curve based on signals from the yaw rate sensor etc., the Millimeter Wave Radar Sensor Assembly performs self-diagnosis to check if the sensor beam axis has deviated from the vehicle movement direction. When the Millimeter Wave Radar Sensor Assembly beam axis has deviated, the Forward Recognition Camera detects this, and stores DTC C1A11.
After installing a new Millimeter Wave Radar Sensor Assembly, if sensor beam axis adjustment is not performed, DTC C1A14 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 this information, the Driving Support ECU Assembly sends pre-collision control operation signals. When the vehicle is determined to be driving in a straight line or on a gradual curve based on signals from the airbag sensor assembly etc., the Millimeter Wave Radar Sensor Assembly performs self-diagnosis to check if the sensor beam axis has deviated from the vehicle movement direction. When the Millimeter Wave Radar Sensor Assembly beam axis has deviated, the Driving Support ECU Assembly detects this, and stores DTC C1A11. After installing a new Millimeter Wave Radar Sensor Assembly, if sensor beam axis adjustment is not performed, DTC C1A14 is stored.
What are the Possible Causes of the DTC C1A14 2014 Toyota RAV4?
- Faulty Millimeter Wave Radar Sensor Assembly
- Millimeter Wave Radar Sensor Assembly harness is open or shorted
- Millimeter Wave Radar Sensor Assembly circuit poor electrical connection
- Faulty Forward Recognition Camera (If equipped)
- Faulty Driving Support ECU Assembly
How to Fix the DTC C1A14 2014 Toyota RAV4?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
Code Tech Notes
When the Millimeter Wave Radar Sensor Assembly is replaced with a new one, adjustment of the radar sensor beam axis must be performed.
If the Forward Recognition Camera has been replaced with a new one, be sure to perform Recognition Camera/Target Position Memory and Recognition Camera Axis Adjust.
What is the Cost to Diagnose the Code?
Labor: 1.0
