Unable to Unlock Steering Wheel (Hybrid Control System cannot Start) [07/2020 - ]: Description

The steering lock ECU (steering lock actuator or upper bracket assembly) activates the steering lock motor and moves the lock bar into the steering column to lock the steering.

The steering may not unlock when the lock bar gets stuck in the lock hole of the steering column. In this case, if the ignition switch is turned to ON while shaking the steering wheel, as is done for a vehicle with a mechanical key, the lock bar will be unlocked. If the ID code box (immobilizer code ECU) or hybrid vehicle control ECU is replaced, the system needs to be initialized. Otherwise, the steering cannot be unlocked and the hybrid control system cannot be started.
