Remote Controller Battery ReplacementEIS00DBV
1. Remove installation screw(5) on the rear of remote controller.
2. Place the key with the lower housing(4) facing up. Set a screw-
driver A wrapped with tape into illustration of the lower housing
(4) and separate the lower housing(4) from the upper hous-
ing(1).
CAUTION:
Please use only a small slotted screwdriver A for opening
the key housing.
3. When replacing the circuit board assembly, remove circuit board
assembly(2) from the upper housing(1).
(Circuit board assembly(2): Switch rubber + Board surface)
CAUTION:
Be careful not to touch the printed circuits directly.
4. When replacing the battery.
Remove battery(3) from the lower housing(4) and replace it.
CAUTION:
When replacing battery, be sure to keep dirt, grease and
other foreign materials off the electrode contact area.
5. After replacement, fit the lower and upper housing together, part
and tighten with the screw(5).

INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the theft warning system is controlled by the engine hood and doors.
To activate the theft warning system, BCM must receive signals indicating the doors are closed and locked.
When a door is open, BCM terminal 12, 14, 15 or 16 receives a ground signal from each door switch.
When the engine hood is open, IPDM E/R terminal 41 receives a ground signal
THEFT WARNING SYSTEM ALARM OPERATION
The vehicle security system is triggered by
lopening a door
lopening the hood
ldetecting battery disconnect/connection.
The vehicle security system will be triggered once the system is in armed phase,
when BCM receives a ground signal at terminals 12, 14, 15, 16 (door switch) or IPDM E/R receives a ground
signal at terminal 41 (hood switch).
When the vehicle security system is triggered, siren control unit or horn is activate.
The alarm automatically turns off after 30 seconds, but will reactivate if the vehicle is tampered with again.
THEFT WARNING SYSTEM DEACTIVATION
To deactivate the theft warning system, a door must be unlocked with keyfob.
When the BCM receives either one of these signals or unlock signal from keyfob the theft warning system is
deactivated. (Disarmed phase)

CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II INSPECTION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to the
data link connector.
3. Turn ignition switch ON.
4. Touch “START (NISSAN BASED VHCL)”.
