Code B2781 2014 Toyota RAV4 Description

The Steering Lock ECU and Steering Lock Motor are built into the Steering Lock Actuator Assembly. The Steering Lock ECU detects whether the steering lock is in the lock or unlock position by using the lock position sensor of the steering lock motor. The Steering Lock ECU receives lock and unlock request signals from the Certification ECU (Smart Key ECU Assembly) and responds with lock and unlock operation signals. The Diagnostic Trouble Code (DTC) will be set when the steering lock/unlock position sensor is malfunctioning, or the steering lock motor activation circuit has a short circuit.
