Fuse 

EKS00HM0

●

If fuse is blown, be sure to eliminate cause of incident before
installing new fuse.

●

Use fuse of specified rating. Never use fuse of more than speci-
fied rating.

●

Do not partially install fuse; always insert it into fuse holder prop-
erly.

●

Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.

Fusible Link 

EKS00HM1

A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is
questionable, use circuit tester or test lamp.

CAUTION:

●

If fusible link should melt, it is possible that critical circuit (power supply or large current carrying
circuit) is shorted. In such a case, carefully check and eliminate cause of incident.

●

Never wrap outside of fusible link with vinyl tape. 

●

Never let fusible link touch any other wiring harness, vinyl or rubber parts.

Circuit Breaker (Built Into BCM)

EKS00HM2

For example, when current is 30A, the circuit is broken within 8 to 20
seconds.
A circuit breaker is used for the following systems:

●

Power windows

●

Power sunroof

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)

2007 Pathfinder

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)

PFP:284B7

System Description

EKS00G8E

●

IPDM E/R (Intelligent Power Distribution Module Engine Room) integrates the relay box and fuse block
which were originally placed in engine compartment. It controls integrated relays via IPDM E/R control cir-
cuits.

●

IPDM E/R-integrated control circuits perform ON-OFF operation of relays, CAN communication control,
etc.

●

It controls operation of each electrical component via ECM, BCM and CAN communication lines.

CAUTION:

None of the IPDM E/R integrated relays can be removed.

SYSTEMS CONTROLLED BY IPDM E/R

1.

Lamp control
Using CAN communication lines, it receives signals from the BCM and controls the following lamps:

●

Headlamps (High, Low)

●

Daytime light relay control (Canada only)

●

Parking lamps

●

Tail and license plate lamps

●

Front fog lamps

2.

Wiper control
Using CAN communication lines, it receives signals from the BCM and controls the front wipers.

3.

Daytime light relay control
Using CAN communication lines, it receives signals from the BCM and controls the daytime light relay.

4.

Generator control
Using CAN communication lines, it receives signals from the ECM and controls power generation output. 

5.

Rear window defogger relay control
Using CAN communication lines, it receives signals from the BCM and controls the rear window defogger
relay.

6.

A/C compressor control
Using CAN communication lines, it receives signals from the BCM and controls the A/C compressor
(magnet clutch).

7.

Starter control
Using CAN communication lines, it receives signals from the BCM and controls the starter relay.

8.

Cooling fan control
Using CAN communication lines, it receives signals from the ECM and controls the cooling fan relays.

9.

Horn control
Using CAN communication lines, it receives signals from the BCM and controls the horn relay.

CAN COMMUNICATION LINE CONTROL

With CAN communication, by connecting each control unit using two communication lines (CAN L-line, CAN
H-line), it is possible to transmit a maximum amount of information with minimum wiring. Each control unit can
transmit and receive data, and reads necessary information only.

1.

Fail-safe control

●

When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control.
After CAN communication returns to normal operation, it also returns to normal control.

●

Operation of control parts by IPDM E/R during fail-safe mode is as follows:

Controlled system

Fail-safe mode

Headlamp

●

With the ignition switch ON, the headlamp low is ON. 

●

With the ignition switch OFF, the headlamp low is OFF. 

Tail, license plate and parking lamps

●

With the ignition switch ON, the tail lamp relay is ON. 

●

With the ignition switch OFF, the tail lamp relay is OFF.
