Door sensor NISSAN TERRANO 2004 Service Repair Manual

5. Bleed the air from the rear brake piping.
6. To adjust the LSV correctly, proceed as follows:
a. With unladen vehicle (12 liters of fuel, radiator coolant andengine oil are full). Spare tire, hand tools and mats in desig-
nated positions. Ensure all doors are closed and no one is
inside of the car. Check the length of LSV spring ªLº.
b. If the spring length is different from that specified, move the regulation lever (2) until the specified value is obtained. Move
the LSV lever (1) until it contacts the stopper bolt and recheck
the spring length.Sensor spring length ªLº Hardtop: 211 mm (8.31 in)
Wagon: 209 mm (8.23 in)
NOTE: Do not disturb stopper bolt.
c. Start the engine and run it at idling speed.
d. Slowly depress the brake pedal until an input pressure of 4,805 kPa (48.1 bar, 49 kg/cm
2, 697 psi) is obtained (at the front axle
pressure gauge) and an output pressure of 1,736 - 2,501 kPa
(18 - 26 bar, 17.7 - 25.5 kg/cm
2, 252 - 363 psi) is obtained (at
the rear axle pressure gauge).
If the output pressure at the rear axle pressure gauge is not within
the specified values, adjust LSV spring length as described under
b) until the output pressure measured is within the specified range.
Unit: kPa (bar, kg/cm2, psi)
Front axle* 4,805 (48.1, 49.0, 697)
Rear axle* 1,736 - 2,501 (18 - 26, 17.7 - 25.5, 252 - 363)
* Load conditions as indicated under 6.a, driver seat occupied.

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.
