Immobilizer system control

The immobilizer system is a vehicle theft prevention device that only allows a remote transmitter that has been previously programmed to the vehicle to start the engine.

(See IMMOBILIZER SYSTEM.)

On-board diagnostic system control

The start stop unit is equipped with an on-board diagnosis function which records DTCs in the event of a malfunction.

(See ON-BOARD DIAGNOSIS SYSTEM [START STOP UNIT].)
