EWS I OPERATION







The EWS I system is controlled by the Central Locking System of ZKE, by the On-Board Computer code function (if equipped) or by the DWA system (E31).

The Starter Immobilization Relay is activated when;
- the vehicle is locked from the outside (Central Locking - GM output to Relay).
- the On-Board Code function is set.
- DWA is activated (E31).

An activated relay performs two functions to deter vehicle theft;
- Ignition and Injection functions of DME are disabled (switched high output signal.)
- the KL 50 start signal circuit is opened to prevent starter operation.
