DESCRIPTION
Outline
• IPDM E/R incorporates a power consumption control function that reduces the power consumption accord-
ing to the vehicle status.
• IPDM E/R changes its status (control mode) with the sleep wake up signal received from BCM via CAN com- munication.
Normal mode (wake-up)- CAN communication is normally performed with other control units.
- Individual unit control by IPDM E/R is normally performed.
Low power consumption mode (sleep)- Low power consumption control is active.
- CAN transmission is stopped.
Sleep Mode Activation
• IPDM E/R judges that the sleep-ready conditions are fulfilled when the ignition switch is OFF and none of theconditions below are present. Then it transmits a sleep-ready signal (ready) to BCM via CAN communica-
tion:
- Outputting signals to actuators
- Switches or relays operating
- Output requests are being received from control units via CAN communication.
• IPDM E/R stops CAN communication and enters the low power consumption mode when it receives a sleep
wake up signal (sleep) from BCM and the sleep-ready conditions are fulfilled.
Wake-up Operation
• IPDM E/R changes from the low power consumption mode to the normal mode when it receives a sleep
wake-up signal (wake up) from BCM or any of the following conditions is fulfilled. In addition, it transmits a
sleep-ready signal (not-ready) to BCM via CAN communication to report the CAN communication start:
- Ignition switch ON
- An output request is received from a control unit via CAN communication.

CAN COMMUNICATION CONTROL
When CAN communication with ECM and BCM is impossible, IPDM E/R performs fail-s
afe control. After CAN
communication recovers normally, it also returns to normal control.
If No CAN Communication Is Available With ECM
If No CAN Communication Is Available With BCM
IGNITION RELAY MALFUNCTION DETECTION FUNCTION
• IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it.
• IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation
coil circuit.
• If the ignition relay cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to alert the user to the ignition relay malfunction when the ignition switch is turned OFF.

6. Hold the Signal Tech II against the side of the left front tire, near the valve stem.
7. With the tool held at a 0 to 15 degree angle to the tire, select
“Activate Sensor” from the main menu, then press and release
the “OK” button to activate the s ensor. Once the sensor is acti-
vated, the vehicle parking lamps will flash and the sensor ID will
appear on the CONSULT screen.
8. Repeat steps 6 and 7 for the remaining tires in this order: right front, right rear and left rear.
9. When ID registration is complete, check the following pattern at each wheel.
10. Once all sensors have been activated, select “End” on the CONSULT to finish ID registration.
11. Test drive the vehicle to ensure that the TPMS lamp is OFF and no warning messages are present.
Without CONSULT
1. Adjust the tire pressure for all tires to the recommended value. Refer to WT-54, "Tire Air Pressure".
2. Turn on the Signal Tech II tool [- (J-50190) ] and select “TPMS Check” from the main menu.
3. Select vehicle model and year.
4. When prompted, hold the Signal Te ch II against the side of the
left front tire, near the valve stem.
5. With the tool held at a 0 to 15 degree angle to the tire, press and release the “OK” button to activate the sensor. Once the sensor
is activated, the tool will sound a tone and the tire pressure will
be displayed.
6. Repeat steps 4 and 5 for the remaining tires in this order: right front, right rear and left rear.
7. When prompted, connect the tool to the data link connector. The tool will connect to the BCM, read the VIN, read sensor IDs and
check for TPMS DTCs. Along wit h DTCs detected, one of the
following will be displayed next to each wheel:
- N/A - Not applicable because no ID found by the tool
- OK - Wheel and sensor ar e in original position
- NEW - New ID found compared to BCM
- RT - Wheel has been rotated
- Low Press - Low tire pressure
8. If no DTC is present or the repair has been complet ed, press the “OK” button to register the IDs and clear
DTCs.
9. Test drive the vehicle to ensure that the TPMS lamp is OFF and no warning messages are present.
10. Print a Signal Tech II Audit Report for your records. Refer to the Signal Tech II User Guide for instructions.

Refer to SEC-15, "NISSAN ANTI-THEFT SYSTEM : System Description" for any functions other than engine
start function of Intelligent Key system.
PRECAUTIONS FOR INTELLIGENT KEY SYSTEM
The transponder (the chip for NATS ID verification) is integrated into the Intelligent Key. (For the con-
ventional models, it is integrated into the mechanical key.) Therefore, ID verification cannot be per-
formed by mechanical key only.
In that case, NATS ID verification can be perfor med when Intelligent Key backside is contacted to
push-button ignition switch while brake pedal is depressed. If verification result is OK, engine can be
started.
OPERATION WHEN INTELLIGENT KEY IS CARRIED
1. When the push-button ignition switch is pressed, the BCM activates the inside key antenna and transmits the request signal to the Intelligent Key.
2. The Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to the BCM.
3. BCM receives the Intelligent Key ID signal via remote keyless entry receiver and verifies it with the regis-
tered ID.
4. BCM turns ACC relay ON and transmits the i gnition power supply ON signal to IPDM E/R.
5. IPDM E/R turns the ignition relay ON and starts the ignition power supply.
6. IPDM E/R turns the starter control relay ON for engine starting in advance.
7. BCM detects the selector lever position and brake pedal operation condition.
8. BCM transmits the starter request signal to IPDM E/R and turns the starter relay ON if BCM judges that the engine start condition* is satisfied.
9. Power supply is supplied through the starter relay and the starter control relay to operate the starter motor. CAUTION:
If a malfunction is detected in the Intelligent Key system, the “KEY” warning lamp on the combina-
tion meter illuminates. At that time, the engine cannot be started.
10. When BCM receives feedback signal from ECM indicating that the engine is started, the BCM transmits a stop signal to IPDM E/R and stops cranking by turning OFF the starter motor relay. (If engine start is
unsuccessful, cranking stops aut omatically within 5 seconds.)
CAUTION:
When the Intelligent Key is carried outside of th e vehicle (inside key antenna detection area) while
the power supply is in the ACC or ON position, even if the engine start condition* is satisfied, the
engine cannot be started.
*: For the engine start condition, refer to “IGNIT ION SWITCH POSITION CHANGE TABLE BY PUSH-BUT-
TON IGNITION SWITCH OPERATION”.
OPERATION RANGE
Engine can be started when Intelligent Key is inside the vehicle. However, sometimes engine may not start
when Intelligent Key is on instrument panel or in glove box.
ENGINE START OPERATION WHEN INTELLIGENT KEY IS CONTACTED TO PUSH-BUTTON IG-
NITION SWITCH
When Intelligent Key battery is discharged, NATS ID verification between transponder in Intelligent Key and
BCM is performed when Intelligent Key backside is cont acted to push-button ignition switch while brake pedal
is depressed. If the verification result is OK, engine can be started.
IGNITION SWITCH POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERA-
TION
The ignition switch position can be changed by the following operations:
NOTE:
• When an Intelligent Key is within the detection area of inside key antenna or when Intelligent Key backside is contacted to push-button ignition switch, it is equivalent to the operations below:
• When starting the engine, the BCM monitors under the engine start conditions:
- Brake pedal operation condition
- Selector lever position
- Vehicle speed
Vehicle speed: less than 4 km/h (2.5 MPH)

(In this step, initialization procedure by CONSULT is not necessary)
NOTE:
• When registering new Key IDs or replacing the ECM that is not brand new, refer to CONSULT Immo-
bilizer mode and follow th e on-screen instructions.
• If multiple keys are attached to the key holder, separate them before work.
• Distinguish keys with unregistered key ID from those with registered ID.
