Fuse NKS004DZ
A
q If fuse is blown, be sure to eliminate cause of malfunction before
installing new fuse.
q Use fuse of specified rating. Never use fuse of more than speci-
fied rating. B
q Do not partially install fuse; always insert it into fuse holder prop-
erly.
C
q Remove fuse for "ELECTRICAL PARTS (BAT)" if vehicle is not
used for a long period of time.

CEL083
Fusible Link NKS004E0
E
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: F
q 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- G
function.
q Never wrap outside of fusible link with vinyl tape. Important:
Never let fusible link touch any other wiring harness, vinyl H
or rubber parts. CKIT0163E
Circuit Breaker NKS004E1
The PTC thermistor generates heat in response to current flow. The I
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 J
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)
IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System Description NKS004E2
q 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.
q IPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control and
oil pressure switch signal reception, etc.
q 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, it receives signal from BCM and controls the following lamps:
q Headlamps (HI, LO)
q Tail, parking and license plate lamps
q Front fog lamps
2. Daytime light relay control (for Canada models)
Using CAN communication, it receives signals from BCM and controls the daytime light relay.
3. Wiper control
Using CAN communication, it receives signals from BCM and controls the front wipers.
4. Rear window defogger relay control
Using CAN communication, it receives signals from BCM and controls the rear window defogger relay.
5. A/C compressor control
Using CAN communication, it receives signals from ECM and controls the A/C relay.
6. Cooling fan control
Using CAN communication, it receives signals from ECM and controls cooling fan via cooling fan control
module.
7. Horn control
Using CAN communication, it receives signals from BCM and controls horn relay.
8. Starter motor relay control
Using CAN communication, it receives signals from BCM and controls starter motor relay.
9. Alternator control
Using CAN communication, it receives signal from ECM and controls power generation voltage.
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.
1. Fail-safe control
q 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.
q Operation of control parts by IPDM E/R during fail-safe mode is as follows:
Controlled system Fail-safe mode
q With the ignition switch ON, the headlamp low relay is ON.
Headlamps
q With the ignition switch OFF, the headlamp low relay is OFF.
Tail, parking and q With the ignition switch ON, the tail lamp relay is ON.
license plate lamps q With the ignition switch OFF, the tail lamp relay is OFF.
q With the ignition switch ON, the cooling fan HI operates.
Cooling fan
q With the ignition switch OFF, the cooling fan stops.
Until the ignition switch is turned off, the front wiper LO and HI remains in the same status it was in just
Front wiper
before fail-safe control was initiated.

Rear window defogger Rear window defogger relay OFF
A/C compressor A/C relay OFF
Front fog lamps Front fog lamp relay OFF B
IPDM E/R STATUS CONTROL
In order to save power, IPDM E/R switches status by itself based on each operating condition.
C
1. CAN communication status
q CAN communication is normally performed with other control units.
q Individual unit control by IPDM E/R is normally performed.
D
q When sleep request signal is received from BCM, mode is switched to sleep transient status.
2. Sleep transient status
q Process to stop CAN communication is activated. E
q All systems controlled by IPDM E/R are stopped. When 3 seconds have elapsed after CAN communi-
cation with other control units is stopped, mode switches to sleep status.
3. Sleep status F
q IPDM E/R operates in low power mode.
q CAN communication is stopped.
q When a change in CAN communication line is detected, mode switches to CAN communication status. G
q When a change hood switch or ignition switch signal is detected, mode switches to CAN communica-
tion status.

CAN Communication System Description NKS004E3
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern I
vehicles are equipped with many electronic control units and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected 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. J
CAN Communication Unit NKS004E4
Refer to LAN-50, "CAN System Specification Chart" . PG
Function of Detecting Ignition Relay Malfunction NKS004E5
q When contact point of integrated ignition relay is stuck and cannot be turned OFF, IPDM E/R turns ON tail L
and parking lamps for 10 minutes to indicate ignition relay malfunction.
q When a state of ignition relay having built-in does not agree with a state of Ignition switch signal input by a
CAN communication from BCM, IPDM E/R lets tail lamp relay operate. M

NOTE:
When the ignition switch is turned ON, the tail lamps are OFF.
