ANTI-THEFT ALARM AND CENTRAL DOOR LOCKING (CDL) DESCRIPTION Anti-Theft Alarm The anti-theft alarm system fitted to New Range Rover consists three main areas: - Perimetric protection. - Volumetric protection. - Vehicle angle monitoring. Perimetric Protection The Body Control Unit (BCU) protects the outside of the vehicle by monitoring the condition of all four door switches, the bonnet switch, and the upper tail door switch and sounds the alarm if any are triggered. Volumetric Protection The BCU protects the inside of the vehicle via an volumetric sensor mounted in the centre of the headlining. It the volumetric sensor detects movement within the passenger compartment, it informs the BCU to sound the alarm. When the alarm is first armed, the BCU allows 15 seconds for the air within the passenger corn partment to stabilize. The alarm will then become fully armed after a further 15 seconds. Vehicle Angle Monitoring The BCU protects against the vehicle being illegally towed away, or any of the wheels being stolen by measuring the longitudinal and transverse angle of the vehicle. The angle of the vehicle is monitored by the tilt sensor, which is located beneath the front passenger seat. When the vehicle is first armed the tilt sensor stores the angle of the vehicle it its memory. If the angle changes more than 1.2° (longitudinal) or 1.4° (transverse) the tilt sensor informs the BCU to sound the alarm. After the alarm has been triggered once, the threshold is lowered to 1.1° and 1.3° to make the alarm even more sensitive to vehicle angle movement. NOTE: If the upper tail door is unlocked using the RF transmitter, the tail door switch, volumetric sensor, and tilt sensor will be reactivated 30 seconds after the last door is closed and locked. An anti-theft alarm LED is mounted in the rear view mirror to act as a visual deterrent. The flashing sequence of the LED is dependent upon the status of the anti-theft alarm system. Central Door Locking (CDL) and Superlocking Two levels of locking are available; Central Door Locking (CDL) and Superlocking. CDL locks all doors, the tail door and the fuel filler flap. Superlocking carries out the same function as CDL but also inhibits operation of the interior door handles and sill buttons. Superlocking is activated when either the Radio Frequency (RF) handset or the key is used to lock the vehicle. CDL is activated it the CDL master switch mounted on the fascia is pressed. The HF handset, which is incorporated into the head of the ignition key, has three buttons. Pressing the large 'Land Rover' button once locks all doors and the tail door. This is followed by a single confirmation flash of the hazard warning lamps to inform that the vehicle has been locked successfully. Pressing and holding the 'Land Hover' button for longer than 2 seconds locks all the doors and tail door and also closes any open windows (including the sunroof). Completion of this Is again followed by a single confirmation flash of the hazard warning lamps to inform that the vehicle has been locked successfully. Pressing the unlock 'Arrow' button once unlocks the drivers door. Pressing the unlock 'Arrow' button a second time unlocks the remaining three doors and the tail door. Pressing and holding the 'Arrow' button for longer than 2 seconds opens all the windows and the sunroof. NOTE: Automatic opening and closing of the windows and sunroof is suspended if the lock or unlock button is released before the operation has been completed. A third button on the handset operates the upper tail door lock. A single press of this button will unlock the upper tail door and temporarily suspend operation of the anti-theft alarm system. Once the tail door has been closed the tail door is automatically locked and the anti-theft alarm system reinstated. This is confirmed by a single flash of the hazard warning lamps. OPERATION Anti-Theft Alarm Power Distribution Feed from the positive battery terminal (C0192) is supplied to fusible link 1, fuse 15, fuse 43, and fuse 53 (C0632) on an R wire. All are located in the passenger compartment fuse box. Fuse 15 (C0586) provides a constant battery feed to the Body Control Unit (BCU) (C0660) on an RS wire. The BCU (C0660) is earthed on an NB wire. Fusible link 1 (C0588) provides a constant battery feed to fuse 14 of the rear fuse box (C2024) on an R wire. Fuse 14 (C2022) provides a constant battery feed to the radio frequency (RF) receiver (C0674) on an RB wire. Fuse 43 of the passenger compartment fuse box (C0586) provides a constant battery feed to the following: - The Battery Backed-Up Sounder (BBUS) (C0666) on an RN wire. - The volumetric sensor (C0359) on an RW wire. - The tilt sensor (C0960) on an RB Wire. Fuse 53 of the passenger compartment fuse box (C0583) provides a constant battery feed to the ignition switch (C0028 on V8 vehicles) on an R wire. When the ignition switch is turned to the 'ignition' position current flows across the switch (C0028 on a V8 vehicles) to fuse 6 of the passenger compartment fuse box (C0585) on a G wire. Fuse 6 (C0587) provides an ignition feed to the interior mirror (C0698) on a GW wire. RF Receiver The RF receiver (C0674) is located at the top of the upper tail door and is provided a constant battery feed from fuse 14 of the rear fuse box (C2022) on an RB wire. The RF receiver is connected to an element in the rear screen via a pair of B wires. The RF receiver uses the rear screen element as an aerial. NOTE: The B wires connecting the RF receiver to the rear screen element are not shown on the system circuit diagrams as they are fly leads incorporated into the manufacture of the rear screen. The RF receiver converts high frequency wave forms transmitted by the remote handset into bi-phase, pulsed signals that can be understood by the BCU. The RF receiver (C0674) is connected to the BCU (C0660) by WY wire. Volumetric Sensor The volumetric sensor monitors the inside of the vehicle by emitting a series of ultrasound pulses and measuring the profile of the returned echo. The sensor (C0359) is located the centre of the headlining, and is provided a constant battery feed from fuse 43 of the passenger compartment fuse box (C0586) on an RW Wire. When the anti-theft alarm is armed, the BCU (C0661) 'switches on' the volumetric sensor by providing a pulsed voltage signal to the tilt sensor (C0960) on a BS wire. This signal is relayed to the volumetric sensor (C0359) on a BW wire. If the volumetric sensor detects movement within the passenger compartment, it provides a feed to the BCU (C0661) on a BY wire. The volumetric sensor (C0359) is earthed or an N wire. Tilt Sensor The tilt sensor monitors the angle of the vehicle. If the angle of the vehicle moves more than the thresholds outlined in the Description section the alarm will be triggered. The sensor (C0960) is located beneath the front passenger seat, and is provided a constant battery feed from fuse 43 of the passenger compartment fuse box (C0586) on an RW wire. When the anti-theft alarm is armed, the BCU (C0661) 'switches on' the tilt sensor (C0960) by providing a pulsed voltage signal on a BS wire. When the anti-theft alarm system is activated, the tilt sensor (C0960) provides a voltage pulse to the BCU (C0661) on a BU wire. If this isn't received within a set time, the BCU determines that the unit is defective. If the tilt sensor is triggered it provides a voltage pulse to the BCU (C0661) on a BU wire. Recognizing this signal, the BCU (C0661) returns a pulsed voltage signal to the tilt sensor (C0960) on a BS wire. Battery Backed-Up Sounder (BBUS) The BBUS (C0666) is mounted adjacent the brake servo, and is provided a constant battery feed by fuse 43 of the passenger compartment fuse box (C0586) on an RN wire. Dependant upon market configuration, the BBUS can emit one of three tones: - Continuous. - Pulsed. - Modulated. When the anti-theft alarm is armed, the BCU (C0661) 'switches on' the BBUS by providing a pulsed voltage signal to the tilt sensor (C0960) on a BS wire. This signal is relayed to the BBUS (C0666) on a BG wire. When the alarm is triggered, the BBUS (C0662) provides a feed to the BBUS (C0666) on a BU wire. The BBUS (C0666) is earthed on an N wire. Perimetric Protection The BCU (C0660) is located beneath the front passenger seat, and is provided a constant battery feed from fuse 15 of the passenger compartment fuse box (C0586) on an RS wire. The door, bonnet, and tail door switches are all normally open switches. When any of these panels are opened, the switch contacts close and an earth path is created. The BCU (C0660) monitors the condition of door bonnet and tail door switches as follows: - The BCU monitors the condition of the drivers door switch (Cl449) via the drivers door module (C2058) on a UR then NW wire. The drivers door switch (C1449) is earthed on an N wire. - The BCU monitors the condition of the front passenger door switch (C3451) via the passenger door module (C22057) on a UR then NW wire. The passenger door switch (C1451) is earthed on an N wire. - The BCU monitors the condition of the LH rear passenger door (C0442) on an NS then NG wire. The LH rear passenger door switch (C0442) is earthed on an N wire. - The BCU monitors the condition of the RH rear passenger door (C0442) on an NW then NG wire. The RH rear passenger door switch (C20442) is earthed on an N wire. - The BCU monitors the condition of the bonnet switch (C0007) on a PG wire. The bonnet switch (C0007) is earthed on an N wire. - The BCU monitors the condition of the upper tail door switch (C0383) on an SW wire. The upper tail door switch (C0383) is earthed on an N wire. NOTE: The LH rear and RH rear passenger door switches have the same connector member as they utilize the same harness. Anti-theft Alarm LED The anti-theft alarm LED is located in the rear view mirror. The flashing sequence of the LED (C0698) is controlled by the BCU (C0661) on an SBY wire. Central Door Locking (CDL) Power Distribution Feed from the positive battery terminal (C0192) is supplied to the following on an R wire: - Fusible link 1. - Fuse 11. - Fuse 15. - Fuse 24. - Fuse 60. All are located in the passenger compartment fuse box (C0632). Fuse 15 (C0586) provides a constant battery feed to the BCU (C0660) on an RS wire. Fuse 60 (C0582) also provides a feed to the BCU (C0662) on an RW wire. The BCU (C0660) is earthed on an NB wire. Fuse 24 (C0583) provides a constant battery feed to the passenger door module (C2016) on an RW wire. Fuse 11 (C0585) provides a constant battery feed to the drivers door module (C2017) on an RP wire. Fusible link 1 (C0588) is connected to fuse 14 and fuse 16 of the rear fuse box (C2024) on an R wire. Fuse 14 (C2022) provides a constant battery feed to the RF receiver (C0674) on an RB wire. Fuse 16 provides a constant battery feed to relay 8, which is also located in the rear fuse box. RF Receiver The RF receiver (C0674) is located at the top of the upper tail door and is provided a constant battery feed from fuse 14 of the rear fuse box (C2022) on an RB wire. The RF receiver converts the radio frequency signals from the remote handset and converts them into a digital signals. The RF receiver (C0674) provides the digital signal to the BCU (C0660) on a WY wire. The BCU processes the signal from the RF receiver and carries out the appropriate function. CDL Master Switch The non-latching CDL master switch is mounted on the fascia, below the hazard warning switch. The BCU (C0661) monitors the condition of the switch (C0700) by providing a feed on an SN wire. When the switch is pressed, the switch contacts close and a momentary earth is created on an N wire. When the BCU registers this earth, it will lock all four doors, the tail door, and the fuel filler flap. Pressing the button a second time unlocks all four doors, the tail door and the fuel filler flap. NOTE: Superlocking is not initiated when the CDL master switch is pressed. Drivers Door The BCU controls operation of the drivers door lock via the drivers door module. The drivers door module (C22017) is provided a constant battery feed from fuse 11 of the passenger compartment fuse box (C0585) on an RP wire. The module (C2017) is earthed on an N wire. The BCU (C0660) communicates with the drivers door module (C2058) via the P-bus on a UR wire. If the drivers door module (C2058) receives an unlock signal from the BCU, it provides a feed to the door lock motor (C1449) on a U wire. Current flows across the motor (C1449) and is provided an earth path via the drivers door module (C2058) on a B wire. The drivers door can also be unlocked using the key. The drivers door module (C2058) monitors the condition of the door lock barrel switch (C1449) on a WB wire. When the door lock is moved to the unlock position, the switch contacts close and an earth path is created on an N wire. Sensing this, the drivers door module unlocks the drivers door. If the drivers door module (C2058) receives a lock signal from the BCU, it provides a feed to the door lock motor (C1449) on a B wire. Current flows across the motor (C1449) and is provided an earth path via the drivers door module (C2058) on a U wire.

Anti theft system components

Customer: replied 14 days ago.
Does the hood have to be closed also
Expert:  Chad Farhat replied 14 days ago.

yes you have to have it closed because the alarm hood switch needs to be closed ,before the lock and unlock with key

Expert:  Chad Farhat replied 14 days ago.

that Hood switch( also called Bonnet switch) will be # 3 in the diagram, if you locate it and don't want to shut hood, but a duck tape on it or something to hold switch down

Customer: replied 14 days ago.
Wow... I never closed the hood back down.
Expert:  Chad Farhat replied 14 days ago.

well maybe it will work for you hopefully :)

Customer: replied 14 days ago.
I'm waiting the 15 minutes the hood is closed...doors never got opened... So I'm waiting the 15 minutes
Expert:  Chad Farhat replied 14 days ago.

ok cool , let me know

Chad

Customer: replied 14 days ago.
sir
Expert:  Chad Farhat replied 14 days ago.

Thanks

Customer: replied 14 days ago.
Didn't work
Expert:  Chad Farhat replied 14 days ago.

1-as you can see several Components are involved and any of them bad can trigger that .

2-I would do it few times the reset ,if not it will be best to invest in proper scanning so we can narrow it down ,is it the key lost the sync, the module , the antenna receiver, door switch ,hood switch etc ...

3- Check all fuse in all fuse box with a test light

4- I wish i can confirm it for you but I will be guessing with out that info, now the hood switch ,key fob circuit board, that send rf signal or the receiver are most common failures

Customer: replied 14 days ago.
Can't gain access inside vehicle...will try your reset again
Expert:  Chad Farhat replied 14 days ago.

you can not use the blade metal key in the driver door and open manualy ?

Customer: replied 14 days ago.
No ... It just turns as if there's nothing in there
Expert:  Chad Farhat replied 14 days ago.

oh, i see, the lock cylinder froze and now you can not unlock and also can not disarm the system since the cylinder want turn

try reset again but i doubt it will work .

next get a lock smith ,pop it open and take door panel apart and check the lock cylinder, is this first time this happens

'

Customer: replied 14 days ago.
its the first time this has happened... Still no access..
Expert:  Chad Farhat replied 14 days ago.

I m sorry man ,nothing else you can do other than what i mentioned earlier

lock smith ,door panel apart ,then you can also scan , you need access to it ,i doubt you have one ,but in rear at license plate is there a place to insert the metes key to open the trunk lift gate ?

Please let me know

Thank You

No sir... No key insert for trunk....buzzard luck..if I get into vehicle by breaking glass... Will it still start even though its in super lock
Expert:  Chad Farhat replied 14 days ago.

NO IT WILL NOT START AND YOU WILL PAY TO FIX THE WINDOW GLASS for nothing, THAT CYLINDER NOT LOCKING IS AN ISSUE for alarm being triggered . And why battery died , get a lock smith ,get access to inside be my advice ,wish there was something else i can tell you to do but there is not much you can do if you don't gain access to inside from what you describing to me

Please let me know if you need anything else

Thank You
