Fuse NKS003G8

If fuse is blown, be sure to eliminate cause of malfunction 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 LinkNKS003G9
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 mal-
function.

Never wrap outside of fusible link with vinyl tape. Important:
Never let fusible link touch any other wiring harness, vinyl
or rubber parts.
Circuit Breaker NKS003GA
The PTC thermistor generates heat in response to current flow. The
temperature (and resistance) of the thermistor element varies with
current flow. Excessive current flow will cause the element's temper-
ature to rise. When the temperature reaches a specified level, the
electrical resistance will rise sharply to control the circuit current.
Reduced current flow will cause the element to cool. Resistance falls
accordingly and normal circuit current flow is allowed to resume.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionNKS003GB

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 relay via IPDM E/R control cir-
cuit.

IPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control, oil
pressure switch signal, and hood switch signal reception, etc.

It controls operation of each electrical part 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 line, it receives signal from BCM and controls the following lamps:

Headlamps (Hi, Lo)

Parking, license plate, side marker and tail lamps

Front fog lamps
2. Wiper control Using CAN communication line, it receives signals from BCM and controls the front wipers.
3. Rear window defogger relay control Using CAN communication line, it receives signals from BCM and controls the rear window defogger
relay.
4. A/C compressor control Using CAN communication line, it receives signals from ECM and controls the A/C compressor.
5. Cooling fan control Using CAN communication line, it receives signals from ECM and controls cooling fan.
6. Horn control Using CAN communication line, it receives signals from BCM and controls 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 maximum amount of information with minimum wiring. Each control unit can
transmit and receive data, and reads necessary information only.
Fail- Safe Control

When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control.
After CAN communication recovers normally, 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.
Parking, license plate side marker and
tail lamps

With the ignition switch ON, the parking, license plate, side marker and tail lamps is ON.

With the ignition switch OFF, the parking, license plate, side marker and tail lamps is OFF.
Cooling fan

With the ignition switch ON, the cooling fan HI operates.

With the ignition switch OFF, the cooling fan stops.
Front wiper Until the ignition switch is turned off, the front wiper LO and HI remains in the same status it
was in just before fail-safe control was initiated.
Rear window defogger Rear window defogger relay is OFF
A/C compressor A/C compressor is OFF
Front fog lamps Front fog lamp is OFF

1. CHECK FUSE AND FUSIBLE LINK
Make sure the following fusible links or IPDM E/R fuses are not blown.
OK or NG
OK >> GO TO 2.
NG >> If fuse or fusible link blown, be sure to eliminate cause of malfunction before installing new one.
2. CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R harness connector E3.
3. Check voltage between IPDM E/R harness connector E3 termi- nals 1, 2 and ground.
OK or NG
OK >> GO TO 3.
NG >> Replace IPDM E/R power supply circuit harness.
3. CHECK GROUND CIRCUIT
1. Disconnect IPDM E/R harness connectors E8 and E9.
2. Check continuity between IPDM E/R harness connectors E8 ter- minal 38, E9 terminal 50, 60 and ground.
OK or NG
OK >> INSPECTION END
NG >> Replace ground circuit harness of IPDM E/R.
