General Description

The anti-theft immobilizer reader module and the Ignition Switch Key Lock Solenoid (N376) are integrated in the access/start authorization switch (E415) and cannot be replaced separately.

All faults related to the access/start authorization switch are transmitted via the access/start authorization control module and the Comfort System Central Control Module (J393).

In this vehicle, the ignition key lock is electro-mechanically released.

• To remove ignition key in vehicles with automatic transmission, always shift selector lever into position "P" and then switch off ignition. Otherwise, ignition switch key lock solenoid prevents the key from being removed (key lock)!

The ignition key lock assures that the ignition key is not accidentally removed.

DTC Recognition and Display

The access/start authorization is equipped with OBD, which makes it easier to perform Fault Finding.

The "Guided Fault Finding" function is to be used for troubleshooting of the systems as described in => [ Vehicle Diagnosis, Testing and Information Systems ] Testing and Inspection.
