Access/Start Authorization System Overview
Access/Start Authorization System Overview
DTC recognition and display
The access/start authorization system has OBD.
Use Vehicle diagnostic tester in "Guided Fault Finding".
General Information
The access/start authorization regulates keyless opening, locking and starting of the vehicle.
Opening
The ID sensor in ignition key must be located within reception range of lock location (approximately 1.5 meters (5 ft.)). The proximity sensor located on the inside of the door handle is activated whenever the handle is touched. This then speaks to the ID sensor inside the key and the door unlocks immediately if the identification is valid. Pulling the door handle opens the vehicle.
Starting
The ID sensor in ignition key must be located in the vehicle interior. The clutch pedal must pressed on manual transmission vehicles. On vehicles with an automatic transmission and DSG, the selector lever must be in "P" and the brake pedal must be pressed. Press the start system button (E378) briefly. This speaks to the ID sensor in the key and if the identification is valid, the steering wheel unlocks and the vehicle can be started.
It is only possible to start the engine with the start system button when a valid ID sensor is located in the vehicle interior.
Locking
The ID sensor in ignition key must be located within reception range of lock location (approximately 1.5 meters (5 ft.)). Touching the locking sensor on the outside of the door handle activates the sensor. This then speaks to the ID sensor inside the key and the vehicle unlocks if the identification is valid.
The access/start authorization control module (J518) controls all access/start functions.
