IPDM E/R

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.

FRONT WIPER PROTECTION FUNCTION

IPDM E/R detects front wiper stop position by a front wiper auto stop signal.
When a front wiper stop position signal is in the conditions listed below, IPDM E/R stops power supply to wiper
after repeating a front wiper 10 seconds activation and 20 seconds stop five times.

Cooling fan

• Turns ON the cooling fan relay-2 and the cooling fan relay-3 when ignition switch is turned ON (Cooling

switch is turned OFF (Cooling fan does not operate)

• Headlamp high relay OFF

• Parking  lamp
• License plate lamp
• Side maker lamp
• Illumination
• Tail lamp

• Turns ON the tail lamp relay when the ignition switch is turned ON
• Turns OFF the tail lamp relay when the ignition switch is turned OFF

Front wiper motor

• The status just before activation of fail-safe control is maintained until the ignition switch is turned OFF 

while the front wiper is operating at LO or HI speed.

• The wiper is operated at LO speed until the ignition switch is turned OFF if the fail-safe control is acti-

vated while the front wiper is set in the INT/AUTO mode and the front wiper motor is operating.

• Returns automatically wiper to stop position when ignition switch is turned ON if fail-safe control is acti-

vated while front wiper motor is operated and wiper stop in the other than stop position.

Description

INFOID:0000000008463309

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.

PRECAUTION

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000008463321

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

COMPONENT PARTS

Ignition Relay

INFOID:0000000008463326

BCM turns ON the following relays to supply ignition power supply or ignition switch ON signal to each ECU
when the ignition switch is turned ON.
• Ignition relay (fuse block)
• Ignition relay (IPDM E/R)
BCM compares following status comparing.
• Ignition relay (fuse block) control signal, and power supply position judged by BCM
• Ignition relay (IPDM E/R) control request, and Ignition relay (IPDM E/R) status

Accessory Relay

INFOID:0000000008463327

BCM turns ON the accessory relays to supply accessory power supply or ignition switch ACC signal to each
ECU when the ignition switch is turned ACC or ON.
BCM compares status of accessory relay control signal, and power supply position judged by BCM.

Blower Relay

INFOID:0000000008463328

BCM turns ON the blower relay to supply ignition power supply or ignition switch ON signal to each ECU when
the ignition switch is turned ON.
BCM compares status of blower relay control signal, and power supply position judged by BCM.

Push-Button Ignition Switch

INFOID:0000000008463329

BCM transmits the change in the power supply position with the push-button ignition switch to IPDM E/R via
CAN communication line. IPDM E/R transmits the power supply position status via CAN communication line to
BCM.

Stop Lamp Switch

INFOID:0000000008463330

Stop lamp switch detects that brake pedal is depressed, and then transmits the signal to BCM.

TCM

INFOID:0000000008463331

TCM detects shift position P or N, transmits P/N position signal to BCM.

POWER DISTRIBUTION SYSTEM

POWER DISTRIBUTION SYSTEM : System Description

INFOID:0000000008463332

SYSTEM DESCRIPTION

• PDS (POWER DISTRIBUTION SYSTEM) is the system that BCM controls with the operation of the push-

button ignition switch and performs the power distribution to each power circuit. This system is used instead
of the mechanical power supply changing mechanism with the operation of the conventional key cylinder.

• The push-button ignition switch can be operated when Intelligent Key is in the following condition.
- Intelligent Key is in the detection area of the inside key antenna
- Insert Intelligent Key into the key slot
• The push-button ignition switch operation is input to BCM as a signal. BCM changes the power supply posi-

tion according to the status and operates the following relays to supply power to each power circuit.

- Ignition relay (inside IPDM E/R)
- Ignition relay (inside fuse block)
- Accessory relay
- Blower relay

NOTE:
The push-button ignition switch operation changes due to the conditions of brake pedal, selector lever and
vehicle speed.

• The power supply position can be confirmed with the lighting of the indicators around the push-button igni-

tion switch.

BATTERY SAVER SYSTEM

When all the following conditions are met for 30 minutes, the battery saver system will cut off the power supply
to prevent battery discharge.
• The ignition switch is in the ACC position
• All doors are closed
• Selector lever is in the P position

Reset Condition of Battery Saver System

If any of the following conditions are met the battery saver system is released.
• Opening any door
• Operating with door key cylinder on door lock
• Operating with door request switch on door lock
• Operating with Intelligent Key on door lock
• Press push-button ignition switch and ignition switch will change to ACC position from OFF position.

POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERA-
TION

The power supply position changing operation can be performed with the following operations.
NOTE:
• When an Intelligent Key is within the detection area of inside key antenna and when it is inserted to the key

slot, it is equivalent to the operations below.

• When starting the engine, the BCM checks the following conditions and then changes the power supply

position.

- Brake pedal operating condition
- Selector lever position
- Vehicle speed

Vehicle speed: less than 4 km/h (2.5 MPH)
