Fuse NISSAN TERRANO 2004 Service Repair Manual

Trouble Diagnoses
If doors can not be unlocked by remote controller operation then the following procedure is required.
A) Unlock the vehicle by a mechanical key in the drivers door key cylinder.Note: this may cause the alarm to sound.
B) Put the key in ignition, turn to ON position for at least five seconds. Assuming the ignition key contains a valid transponder then a signal will be generated by the immobilizer which will disarm the alarm and allow
key learn mode to be entered.
C) Turn ignition OFF and wait for ten seconds.

SETTING THE THEFT WARNING SYSTEM
Initial condition
(1) Close all doors.
(2) Close hood.
Pre-armed phase and armed phase
The theft warning system turns into the ªpre-armedº phase when hood and all doors are closed and locked by
key or multi-remote controller. (The security indicator lamp blinks intermittently for 30 seconds.)
After about 30 seconds, the system automatically shifts into the ªarmedº phase (the system is set).
CANCELING THE SET THEFT WARNING SYSTEM
When the following (a) or (b) operation is performed, the armed phase is canceled.
(a) Unlock the doors with the multi-remote controller.
(b) Insert key in ignition key cylinder and turn it to ON. Then NATS IMMU will send a disarm signal to the timecontrol unit.
ACTIVATING THE ALARM OPERATION OF THE THEFT WARNING SYSTEM
Make sure the system is in the armed phase. When the following operation (a) (b) (c) or (d) is performed, the
system sounds the horns and flashes the hazard lamp for about 30 seconds.
(a) Engine hood or any door is opened before unlocking door with the multi-remote controller.
(b) A door is unlocked without using the multi-remote controller.
(c) The ignition is switched ON without using a NATS registered key.
(d) The ultrasonic sensing is triggered.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times.
IThrough 10A fuse [No.
16, located in the fuse block (J/B)]
I to combination meter (security indicator lamp) terminal q
27.
I through 10A fuse [No.
5, located in the fuse block (J/B)]
I to time control unit terminal
U09.
With the ignition switch in the ON or START position, power is supplied
I through 10A fuse [No.
26, located in the fuse block (J/B)]
I to time control unit terminal
U01.
Ground is supplied
I to time control unit terminal
U16
Ithrough body groundsF36andF47(LHD models), orM33andM754(RHD models).
INITIAL CONDITION TO ARM THE SYSTEM
The operation of the theft warning system is controlled by all the doors and hood.
To activate the theft warning system, the time control unit must receive signals indicating all the doors and
hood are closed and the doors are locked.
When a door is open, time control unit terminal
U06orU07receives a ground signal from each door switch.
When a door is unlocked, time control unit terminal
U25,U35orU36receives a ground signal from each door
unlock sensor.
When the hood is open, time control unit terminal
U32receives a ground signal
I from the hood switch
I through body grounds
M33andM754.

System Description (Cont'd)
EL-245

THEFT WARNING SYSTEM ARMING (With key or remote controller used to lock doors)
If the key is used to lock doors, time control unit terminalU29receives a ground signal
I from terminal q
2of the key cylinder switch
I through body grounds
B18andB10.
If this signal or lock signal from remote controller is received by the time control unit, the theft warning sys-
tem will arm automatically.
When arming the theft warning system, time control unit terminal
U18supplies ground intermittently to termi-
nal q
40of the combination meter. The security lamp will blink intermittently for approximately 30 seconds (and
then blink every 2.6 seconds, due to NATS).
Now the theft warning system is in armed phase.
THEFT WARNING SYSTEM ALARM OPERATION
The theft warning system is triggered by
I opening a door
I opening back door
I opening the hood
I unlocking door without using the multi-remote controller
I switching the ignition ON without a NATS registered key
I triggering the ultrasonic sensors
Once the theft warning system is in armed phase, if the time control unit receives a signal at terminal
U25,
U35,U36(door unlock sensor),U06,U07(door switch),U32(hood switch), orU30(ultrasonic sensor) the theft
warning system will be triggered. The hazard lamps flash and the horn sounds intermittently.
Power is supplied at all times
I through 10A fuse [No.
16, located in the fuse block (J/B)]
I to theft warning horn relay.
If the theft warning system is triggered, ground is supplied
I from terminal
U43of the time control unit
I to theft warning horn relay.
The hazard lamps flash and the horn sounds intermittently.
The alarm automatically turns off after 30 seconds but will reactivate if the vehicle is tampered with again, or
if the initial cause remains present.
THEFT WARNING SYSTEM ALARM DISARMING
The theft warning system alarm operation can be deactivated by either unlocking the vehicle with the remote
controller, or turning the ignition to the ªONº position with a registered NATS key.
