Locking of Steering Lock The battery voltage must be greater than V and the vehicle must be stationary. The ABS ECU transmits vehicle speed on a hardwired connection with the steering lock ECU. The steering lock ECU uses the signal to determine when the vehicle has stopped. When the key is removed and the steering lock ECU receives the 'no valid key in lock' message from the immobilisation ECU, the steering lock motor is activated. The safety release solenoid actuator in the steering column is energised, withdrawing the pin from the locking bolt. The Hall sensor in the solenoid actuator informs the steering lock ECU that the lock is released. The steering lock ECU then operates the steering lock motor in the lock direction. Movement from the unlocked to the locked position is detected by the Hall sensor in the motor and sensed by the steering lock ECU. The safety release solenoid actuator is de-energised and rests on the locking bolt.
