Control of the electronic steering lock

After authentication by the CAS, current is applied to the electronic steering lock. Only at this point can the lock be unlocked or locked.

The engine may only be started if the electronic steering lock has been unlocked and secured.

The electronic steering lock can only be locked when the vehicle is stationary and the engine has been stopped.

If no unlocking procedure or locking procedure is carried out, the electronic steering lock is rendered free of current and deadlocked.
