Tech Notes for C1A14 2017 Toyota RAV4

When replacing the Driving Support ECU Assembly, make sure to replace it with a new one. If a device that was installed on another vehicle is used, the information stored in the Driving Support ECU Assembly will not match the information from the vehicle, and as a result, a DTC may be stored.

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.
