System DescriptionEIS001RE
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 ignition switch must be at OFF.
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 terminal 5

to time control unit terminal 32.
Then time control unit operates to lock doors and set super lock (models with super lock).
UNLOCK OPERATION
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 terminal 6

to time control unit terminal 33.
Time control unit operates to unlock driver's door and release super lock (models with super lock).
Then, if an unlock signal is sent from the remote controller again within 5 seconds, all other doors will be
unlocked.
HAZARD REMINDER
When the doors are locked or unlocked by multi-remote controller (signal from driver side unlock sensor), sup-
ply power to hazard warning lamp flashes 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.
To enter ID code entry, the following signals must be input to the multi-remote control unit.

Ignition switch (ON)

Signal from remote controller
For detailed procedure, refer to BL-89, "
ID Code Entry Procedure" .

NATS (NISSAN ANTI-THEFT SYSTEM)

System CompositionEIS001RS
The immobilizer function of the NATS consists of the following:

NATS ignition key

NATS immobilizer control unit (IMMU) located in the ignition key cylinder

Engine control module (ECM)

Dongle unit (RHD models)

Security indicator
ECM Re-communicating FunctionEIS008F1
Performing following procedure can automatically perform re-communication of ECM and NATS IMMU, but
only when the ECM has been replaced with a new one (*1).
*1: New one means a virgin ECM which has never been energized on-board.
(In this step, initialization procedure by CONSULT-II is not necessary)
NOTE:

When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-II
Operation Manual, NATS.

If multiple keys are attached to the key holder, separate them before work.

Distinguish keys with unregistered key ID from those with registered ID.
1. Install ECM.
2. Using a registered key (*2), turn ignition switch to “ON”.
*2: To perform this step, use the key (except for card plate key) that has been used before performing
ECM replacement.
3. Maintain ignition switch in “ON” position for at least 5 seconds.
4. Turn ignition switch to “OFF”.
5. Start engine.
If engine can be started, procedure is completed.
If engine cannot be started, refer to CONSULT-II Operation Manual NATS and initialize control unit.

OK or NG
OK >> Check harness for open or short between security indi-
cator lamp and NATS IMMU.
NG >> NATS IMMU is malfunctioning.

Replace NATS IMMU. Ref. part No. A

Perform initialization with CONSULT-II.

For initialization, refer to “CONSULT-II operation man-
ual NATS”.
Diagnostic Procedure 7EIS008FC
Self-diagnostic results:
“LOCK MODE” displayed on CONSULT-II screen
1. CONFIRM SELF-DIAGNOSTIC RESULTS
Confirm SELF-DIAGNOSTIC RESULTS “LOCK MODE” is displayed
on CONSULT-II screen.
Is CONSULT-II screen displayed as shown in figure?
Ye s > > G O T O 2 .
No >> GO TO BL-119, "
SYMPTOM MATRIX CHART 1" .
2. ESCAPE FROM LOCK MODE
1. Turn ignition switch OFF.
2. Turn ignition switch ON with registered key. (Do not start engine.) Wait 5 seconds.
3. Return the key to OFF position.
4. Repeat steps 2 and 3 twice (total of three cycles).
5. Start the engine.
Does engine start?
Yes >> System is OK. (Now system is escaped from “LOCK MODE”.)
No >> GO TO 3.
3. CHECK IMMU ILLUSTRATION
Check NATS IMMU installation. Refer to BL-131, "
How to Replace NATS IMMU" .
OK or NG
OK >> GO TO 4.
NG >> Reinstall NATS IMMU correctly.5 (OR) – Ground : Continuity should exist intermittently.

Control OperationEJS004G9
MODE CONTROL DIAL
Controls the air discharge outlets.
Positions the air outlet doors to the defrost position. Also positions the intake doors to the outside air position.
When shifting mode control dial to DEF under the following conditions, compressor is turned ON. (A/C LED
ON)

FAN: O N

A/C: OFF
TEMPERATURE CONTROL DIAL (POTENTIO TEMPERATURE CONTROL)
Increase or decrease the set temperature.
FAN CONTROL DIAL
Automatically or Manually control the blower speed. Twenty-five speeds are available for manual control.
Shifting fan control dial to AUTO, compressor is turned ON automatically.
REAR WINDOW DEFOGGER SWITCH
When illumination is ON, rear window is defogged.
INTAKE SWITCH

When intake switch is ON, REC indicator turns ON, and air inlet is fixed to REC.

When press intake switch again, FRE indicator turns ON, and air inlet is fixed to FRE.

When intake switch is pressed for approximately 1.5 seconds or longer, REC and FRE indicators blink
twice. Then, automatic control mode is entered. Inlet status is displayed even during automatic control.

When DEF position or FRE indicator is turned ON, or when compressor is turned from ON to OFF, REC
switch is automatically turned OFF (fixed to FRE mode).
REC mode can be re-entered by pressing intake switch again. (Except DEF position)
A/C SWITCH
The compressor is ON or OFF.
(Pressing the A/C switch when the fan control dial is ON will turn off the A/C switch and compressor.)
