Code B2205 Lexus Description

The B2205 diagnostic trouble code (DTC) pertains to the kick sensor circuit in Lexus vehicles, particularly those equipped with a smart key system that allows for hands-free access and operation. The kick sensor is typically located near the rear bumper and is designed to detect a foot movement underneath the vehicle, enabling the trunk to open automatically without the need for physical contact with the key fob. This feature enhances convenience, especially when hands are full.
