1998 NISSAN PATROL multi remote

System Description
FUNCTION
Multi-remote control system has the following function.
+Door lock (and set super lock)
+Door unlock (and release super lock)
+Hazard reminder
LOCK OPERATION
To lock door by multi-remote controller, the following two signals must be received.
+Key switch OFF (when ignition key is not in ignition key cylinder.)
+All door switches CLOSED
When the LOCK signal is input to multi-remote control unit (the antenna of the system is combined with multi-
remote control unit), ground is supplied
+through multi-remote control unit terminalj
10
+to super lock control unit terminalj2.
Then super lock control unit operates to lock doors and set super lock.
UNLOCK OPERATION
To unlock door by multi-remote controller, the following signal must be received.
+Key switch OFF (when ignition key is not in ignition key cylinder)
When the UNLOCK signal is input to multi-remote control unit (the antenna of the system is combined with
multi-remote control unit), ground is supplied
+through multi-remote control unit terminalj
11
+to super lock control unit terminalj3.
Then super lock control unit operates to unlock doors and release super lock.
HAZARD REMINDER
When the doors are locked or unlocked by multi-remote controller, ground is supplied
+to terminalj
1of multi-remote control relay-1 and 2
+through multi-remote control unit terminalj
12.
Then the relays are energized and hazard warning lamp ¯ashes as follows
+Lock operation: Flash once
+Unlock operation: Flash twice
MULTI-REMOTE CONTROLLER ID CODE ENTRY
A maximum of four remote controllers can be entered. Any attempt to enter a remote controller will erase all
ID codes previously entered. Therefore, be sure to receive all remote controllers from the vehicle owner when
any ID code entry is performed.
To enter ID code entry, the following signals must be input to the multi-remote control unit.
+Driver side LOCKED signal (from driver side door unlock sensor)
+Door switch CLOSED signal
+Key switch signal (INSERTED/WITHDRAWN)
+Accessory power supply
+Signal from remote controller
For detailed procedure, refer to ``ID Code Entry Procedure'' in EL-239.

ID Code Entry Procedure
Note:
A maximum of four remote controllers can be entered. Any attempt to enter a remote controller will
erase all ID codes previously entered. Therefore, be sure to receive all remote controllers from the
vehicle owner when any ID code entry is performed.
Enter the identity (ID) code manually when:
+remote controller or control unit is replaced.
+an additional remote controller is activated.
To enter the ID code, follow the procedures below.
PROCEDURE
Close all doors and lock driver side door.
Insert and remove the key from the ignition more than six times within 10 seconds.
Turn ignition key switch to ``ACC'' position. (The hazard warning lamps will then
¯ash twice.
Push any button on the new remote controller once. (The hazard warning lamps will
then ¯ash twice.)
At this time, the new ID code is entered and all previous ID memory is com-
pletely erased.
b
Do you want to enter any additional remote controller ID codes?
A maximum four ID codes may be entered. Any attempt to enter more will be
ignored.
No Yes
ADDITIONAL ID CODE ENTRY
Release the door lock, then lock again
with driver side knob lock switch.
Open driver side door or turn the ignition key switch to ``OFF'' position.
END.
After entering the identity (ID) code, check the operation of multi-remote con-
trol system.
NOTE:
+If you need to activate more than two additional new remote controllers, repeat the procedure
``Additional ID code entry'' for each new remote controller.
+If the same ID code that exists in the memory is input, the entry will be ignored.
+Entry of maximum four ID codes is allowed and any attempt to enter more will be ignored.
+Any ID codes cannot be entered after termination of the ``setting mode''.
