LR3/Disco 3
The RF receiver converts the signals from the remote handset into digital messages and transmits them to the CJB
(central junction box) . The RF receiver is installed above the headlining, on the cross-rail between the top of the B pillars.
Operation of the RF receiver is powered by a permanent battery feed from the CJB (central junction box) .
CLS OPERATION
The CLS allows the doors and, where applicable, the fuel filler door, to be centrally locked and unlocked using the remote
handset or the CLS switches. Depending on the market, the CLS has either two or three locking states: internally locked,
externally locked and superlocked (all except NAS).
Configurable CLS features include automatic speed locking, automatic relocking and SPE. All vehicles incorporate crash
unlocking.
The internally locked state is activated with a single press of the CLS lock switch. The method of activating the externally
locked and superlocked states is market dependant:
In all markets except NAS, a single press of the lock button on the remote handset activates the superlocked
state. A second press of the lock button on the remote handset, within 2 seconds of the first press, changes the
CLS to the externally locked state.
In NAS markets, a single press of the lock button on the remote handset activates the externally locked state. A
second press of the lock button on the remote handset, within 2 seconds of the first press, arms the active anti-
theft system. For additional information, refer to
Anti-Theft - Active
(419-01A )
In the internally locked state:
The exterior door handles are disengaged from the latches, to prevent the doors being opened from outside the
vehicle.
The CJB (central junction box) ignores inputs from the tailgate release switch, which prevents the tailgates being
opened.
The doors can be opened using the internal door handles.
The vehicle can be unlocked using a single press of the CLS unlock switch or a single press of the unlock button
on the remote handset.
In the externally locked state:
In addition to the conditions adopted for the internally locked state, the CJB (central junction box) also ignores
inputs from the CLS lock and unlock switches.
The vehicle can be unlocked using a single press of the unlock button on the remote handset.
In the superlocked state:
In addition to the conditions adopted for the externally locked state, the CJB (central junction box) activates: The
superlock motors in the door latches, to disengage the interior door handles. The fuel filler door lock motor (where
fitted), to secure the fuel filler door.
The superlock motors in the door latches, to disengage the interior door handles.
The fuel filler door lock motor (where fitted), to secure the fuel filler door.
The vehicle can be unlocked using a single press of the unlock button on the remote handset.
When the CLS lock switch is used, the CJB (central junction box) will internally lock the vehicle regardless of the position
of the ignition switch, with or without the key in the ignition switch and with or without the engine running.
