Engine Immobilization Function

(Not On All Vehicles!)
The engine will be immobilised whenever the theft alarm is armed.

The vehicle may only be mobilised by using the handset or entering the correct EKA code.

The electronic engine immobilisation is controlled jointly by the engine management system's Electronic Control Module (ECM) (Z132) and the Theft Alarm Unit (Z163).

When the Theft Alarm Unit (Z163) immobilises the vehicle, it sends a signal to the ECM. The ECM then immobilises the engine management system until a mobilise signal is received from the Theft Alarm Unit (Z163).
