IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
Revision: 2004 November 2004 FX35/FX45
IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionAKS005S9

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

IPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control, oil
pressure switch signal, 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 lamps

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 relay.
5. Cooling fan control
Using CAN communication line, it receives signals from ECM and controls cooling fan relay.
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.
1. 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.
Tail and parking lamps

With the ignition switch ON, the tail and parking lamps is ON.

With the ignition switch OFF, the tail and parking 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 wiperUntil 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 OFF
A/C compressor A/C compressor OFF
Front fog lamps Front fog lamp relay OFF

FRONT WIPER AND WASHER SYSTEM
Revision: 2004 November 2004 FX35/FX45
FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationAKS0056O
System DescriptionAKS0056P

All front wiper relays (HI, LO) are included in IPDM E/R.

Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by BCM when switch is turned ON.

BCM controls front wiper LO, HI, and INT (intermittent) operation.

IPDM E/R operates wiper motor according to CAN communication signals from BCM.
Power is supplied at all times

through 50 A fusible link (letter M, located in fusible link block)

to BCM (body control module) terminal 55

through 15 A fuse [No. 22, located in fuse block (J/B)]

to BCM (body control module) terminal 42

through 30 A fuse [No. 73, located in IPDM E/R (intelligent power distribution module engine room)]

to front wiper relay [located in IPDM E/R (intelligent power distribution module engine room)]

through 15 A fuse [No. 78, located in IPDM E/R (intelligent power distribution module engine room)]

to CPU (central processing unit) [located in IPDM E/R (intelligent power distribution module engine room)]

through 10 A fuse [No. 71, located in IPDM E/R (intelligent power distribution module engine room)]

to CPU (central processing unit) [located in IPDM E/R (intelligent power distribution module engine
room)].
When the ignition switch ON or START position, power is supplied

through 15 A fuse [No. 1, located in fuse block (J/B)]

to BCM (body control module) terminal 38

through ignition relay [located in IPDM E/R (intelligent power distribution module engine room)]

to front wiper relay [located in IPDM E/R (intelligent power distribution module engine room)]

through 10 A fuse [No. 84, located in IPDM E/R (intelligent power distribution module engine room)]

through IPDM E/R (intelligent power distribution module engine room) terminal 44

to front washer motor terminal 1.
Ground is supplied

to BCM terminals 49 and 52

through grounds M35, M45 and M85

to IPDM E/R terminals 38 and 60

through grounds E21, E50 and E51

to combination switch (wiper switch) terminal 12

through grounds M35, M45 and M85.
LOW SPEED WIPER OPERATION
When wiper switch is in LO position, BCM detects low speed wiper ON signal by BCM wiper switch reading
function.
BCM sends front wiper request signal (LO) with CAN communication line

from BCM terminals 39 and 40

to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper request signal (LO), it turns ON front wiper relay (located in IPDM E/R),
power is supplied

to front wiper motor terminal 1

through IPDM E/R terminal 21 and front wiper relay and front wiper HI relay.
Ground is supplied

to front wiper motor terminal 2

through grounds E21, E50 and E51.
With power and ground supplied, the front wiper motor operates at low speed.
HI SPEED WIPER OPERATION
When wiper switch is in HI position, BCM detects high speed wiper ON signal by BCM wiper switch reading
function.
BCM sends front wiper request signal (HI) with CAN communication line

from BCM terminals 39 and 40

to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper request signal (HI), it turns ON front wiper relay (located in IPDM E/R),
power is supplied

to front wiper motor terminal 4

through IPDM E/R terminal 31 and front wiper relay and front wiper HI relay.
Ground is supplied

to front wiper motor terminal 2

through grounds E21, E50 and E51.
With power and ground supplied, the front wiper motor operates at high speed.
INTERMITTENT OPERATION
Wiper intermittent operation delay interval is determined from a combination of 3 switches (intermittent opera-
tion dial position 1, intermittent operation dial position 2, and intermittent operation dial position 3) and vehicle
speed signal.
During each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.
