Here are the main functions of the EZS in a Mercedes:
1. Ignition Switch:
The EZS serves as the main ignition switch of the vehicle. It allows the driver to start and stop the engine by inserting the key and turning it.
2. Immobilizer:
The EZS incorporates an immobilizer system that prevents the engine from starting if an unauthorized key is used. It authenticates the key's electronic code with the vehicle's electronic control unit (ECU) to ensure that the correct key is being used.
3. Steering Lock:
The EZS controls the steering lock, which engages automatically when the key is removed from the ignition. This feature helps prevent theft by making it difficult to turn the steering wheel.
4. Central Locking System:
In some Mercedes models, the EZS also integrates the central locking system. It manages the locking and unlocking of all vehicle doors, including the trunk, using a single key or the remote key fob.
5. Key Memory Function:
The EZS may have a key memory function that stores the preferences of multiple drivers, such as seat position, mirror settings, and radio presets. This feature allows different users to access their personalized settings when they use their respective keys.
6. Communication with Other Vehicle Systems:
The EZS communicates with various other electronic control units (ECUs) in the vehicle. This allows it to exchange data and synchronize actions related to security, ignition, and other functions.
The EZS is a crucial component in Mercedes vehicles, ensuring that only authorized individuals can start and drive the vehicle. It combines multiple security measures and convenience features to enhance the overall driving experience and protect against theft.
