DESCRIPTION AND OPERATION SECURITY AND CENTRAL DOOR LOCKING
SYSTEM - FROM 02MY
The following description details the functionality and operation of the 10AS Security and Central Door Locking
(CDL) System fitted to 2002MY Defender. The system contains some new features and also retains some
features from previous Defender models. The alarm system and CDL system are controlled by the 10AS anti-theft
alarm ECU.
New door lock barrels are introduced and use the same key as the ignition switch barrel, thereby eliminating the
requirement for a separate key for the doors.
NOTE: Some markets will only have some of the features described and some will have no
security or central door locking functions.
The security system comprises the following components:
10AS anti-theft alarm ECU
Remote handset transmitters
Transponder coil
Volumetric sensor
CDL actuators
Bonnet switch
Driver’s door key barrel switch
Door switches
Bonnet switch
Battery Backed-Up Sounder (BBUS) or alarm sounder
Security LED
Engine immobilised warning lamp
Direction indicators
