ETACS refers to a control system which looks after security and convenience features in some vehicles. Since 2005, its role has been expanded to act as a central hub for the car's entire electronic functions.

Electronic Time and Alarm Control System (Early ETACS)

Early ETACS was used to provide security, interior lighting and central locking for vehicles. It has been used in a wide range of Mitsubishi vehicles and first served in the Magna from the TP onwards.

Key to the system are a security system with immobilisation, central locking, interior light timer with dimming, ignition key illumination with timer, a rear window demister which turns off automatically after 20 minutes and a power window system which can be used for 20 seconds after the car is turned off.

Electronic Total Automotive Control System (Newer ETACS)

ETACS was revised and renamed in 2005. As with Early ETACS feautres vary across the Mitsubishi model range. ETACS has grown to become the hub for all the vehicle's electronic functions. It allows for the customisation of standard features and the addition of optional equipment.

The system uses the Controller Area Network (CAN) and Local Interconnect Network protocols (LIN) defined by Bosch. CANs are used to connect various control units (powertrain, safety, entertainment, door lock control, etc) and allow intercommunication between them while LINs complement the CAN to connect sensors, switches and actuators to the car's control units.
