IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionEKS00PA8
lIPDM 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.
lIPDM E/R-integrated control circuits perform ON-OFF operation of relays, CAN communication control,
etc.
lIt 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
IPDM E/R receives a request signal from each Control unit with CAN communication. It controls each system.
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
lWhen 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.
lOperation of control parts by IPDM E/R during fail-safe mode is as follows:
Control system Transmit control unit Control part
Lamp control BCM
lHead lamps (HI, LO)
lTail lamps, parking and license plate lamps
lFront fog lamps
Wiper control BCM Front wipers
Rear window defogger control BCM Rear window defogger
A/C compressor control ECM A/C compressor
Starter control TCM Starter motor
Cooling fan control ECM Cooling fan
Controlled system Fail-safe mode
Headlamps
lWith the ignition switch ON, the headlamp low is ON.
lWith the ignition switch OFF, the headlamp low is OFF.
Tail, parking and license plate lamps
lWith the ignition switch ON, the tail lamp is ON.
lWith the ignition switch OFF, the tail lamp is OFF.
Cooling fan
lWith the ignition switch ON, the cooling fan HI operates.
lWith the ignition switch OFF, the cooling fan stops.
Front wipersUntil 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 OFF
A/C compressor A/C compressor OFF
Front fog lamps Front fog lamp OFF

FRONT WIPER AND WASHER SYSTEM
INTERMITTENT OPERATION
When front wiper switch is turned to INT position, wiper performs intermittent operation, low-speed operation,
and high-speed operation according to water drop increase rate on windshield detected by light and rain sen-
sor. If light and rain sensor malfunctions, it operates as vehicle speed sensing wiper during driving and oper-
ates intermittent operation according to INT-volume switch with vehicle stopped. During this time, BCM
controls each operation.
The BCM then sends a front wiper (HI or LOW) request signal with CAN communication.
lfrom BCM terminals 21 and 22
lto IPDM E/R terminals 39 and 40.
When the BCM determines that combination switch status is front wiper intermittent ON, it performs the follow-
ing operations.
lBCM detects intermittent wiper dial position.
lBCM sends front wiper request signal (HI or LOW) to IPDM E/R at calculated operation interval.
When IPDM E/R receives front wiper request signal (HI or LOW), it supplies ground to energize the front wiper
main relay and front wiper LOW/HIGH relay. It then sends an auto-stop signal to the BCM, and conducts inter-
mittent front wiper motor operation.
AUTO STOP OPERATION
When the wiper arms are not located at the base of the windshield, and the wiper switch is turned OFF, the
wiper motor will continue to operate until the wiper arms reach the windshield base. When the wiper arms
reach the base of windshield, front wiper motor terminals 2 and 5 are connected.
Ground is supplied
lto IPDM E/R terminal 43
lthrough front wiper motor terminal 5
lthrough front wiper motor terminal 2
lthrough grounds E21, E41 and E61.
The IPDM E/R sends an auto stop operation signal to the BCM with CAN communication.
When the BCM receives an auto stop operation signal, the BCM sends wiper stop signal to the IPDM E/R over
CAN communication lines. The IPDM E/R then de-energizes the front wiper main relay.
The wiper motor will then stop the wiper arms at the STOP position.
FRONT WASHER OPERATION
When the ignition switch is in the ON or START position, and the front washer switches are OFF, the front
washer motor is supplied power
lthrough 10A fuse [No. 15, located in fuse block (J/B)]
lthrough combination switch (wiper switch) terminal 2
lthrough combination switch (wiper switch) terminal 4
lto front washer motor terminal 1.
When the front wiper switch is in the front washer position, the BCM detects a front washer signal request
through the combination switch (wiper switch) reading function.
Combination switch ground is supplied
lto front washer motor terminal 2
lthrough combination switch (wiper switch) terminal 3
lthrough combination switch (wiper switch) terminal 9
lthrough grounds M21, M80 and M83.
With ground supplied, the front washer motor is operated in the front direction.
When the BCM detects that front washer motor has operated for 0.4 seconds or longer, the BCM uses CAN
communication and sends a wiper request signal to the IPDM E/R for low speed operation of wipers.
When the BCM detects that the washer switch is OFF, low speed operation cycles approximately 3 times and
then stops.

WW-8
FRONT WIPER AND WASHER SYSTEM
COMBINATION SWITCH READING FUNCTION
Description
lBCM reads combination switch status, and controls related systems such as headlamps and wipers,
according to the results.
lBCM reads information for a maximum of 20 switches by combining 5 output terminals (OUTPUT 1-5) and
5 input terminals (INPUT 1-5).
Operation Description
lBCM activates transistors of output terminals (OUTPUT 1-5) periodically, and allows current to flow in
turn.
lIf any (1 or more) switches are turned ON, the circuit of output terminals (OUTPUT 1-5) and input termi-
nals (INPUT 1-5) becomes active.
lAt this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-
age of the input terminal (INPUT 1-5) corresponding to that switch changes, the interface in the BCM
detects a voltage change, and the BCM determines that the switch is ON.

Front Wiper Does Not OperateEKS00P56
CAUTION:
During IPDM E/R fail-safe control, front wipers may not operate. Refer toPG-14, "
CAN COMMUNICA-
TION LINE CONTROL"to make sure that it is not in fail-safe status.
1.CHECK IPDM E/R TO FRONT WIPERS
With CONSULT-II
1. Select “IPDM E/R” on CONSULT-II. Select “ACTIVE TEST” on
“SELECT DIAG MODE” screen.
2. Select “FRONT WIPER” on “SELECT TEST ITEM” screen.
3. Touch “LO” or “HI” screen.
Without CONSULT-II
Start up auto active test. Refer toPG-19, "
Auto Active Test".
Does front wiper operate normally?
YES >> GO TO 2.
NO >> GO TO 4.
2.CHECK COMBINATION SWITCH TO BCM (1)
With CONSULT-II
1. Select “BCM” on CONSULT-II. Select “WIPER” on “SELECT
TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
Make sure that “FR WIPER INT”, “FR WIPER LOW” and “FR
WIPER HI” turn ON-OFF according to combination switch (wiper
switch) operation.
Without CONSULT-II
Refer toLT- 11 8 , "
Combination Switch Inspection".
OK or NG
OK >> GO TO 3.
NG >> Check combination switch (wiper switch). Refer toLT-
11 8 , "Combination Switch Inspection".
3.CHECK COMBINATION SWITCH TO BCM (2)
Select “BCM” on CONSULT-II, and perform self-diagnosis for “BCM”.
Displayed self-diagnosis results
NO DTC>> Replace BCM. Refer toBCS-17, "Removal and Instal-
lation of BCM".
CAN COMM CIRCUIT>> Check CAN communication line of BCM.
Refer toBCS-16, "

Front Wiper Does Not Return to Stop Position (After Front Wiper for 10 Sec-
onds, They Stop for 20 seconds, and After Repeating the Operations Five
Times, They Become Inoperative)
EKS00P57
CAUTION:
lWhen auto stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers front wipers are locked, and stops wiper output. That causes this
symptom.
lThis status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”
ITEMS SHOWS “BLOCK”.
1.CHECK FRONT WIPER STOP SIGNAL
With CONSULT-ll
1. Select “BCM” on CONSULT-II. Select “WIPER” on “SELECT
TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
Make sure that “WIP AUTO STOP” turns “ACT P” - “STOP P”
linked with wiper operation.
Without CONSULT-ll
GO TO 2.
Does the front wiper operate normally?
YES >> Replace IPDM E/R. Refer toPG-26, "Removal and
Installation of IPDM E/R".
NO >> GO TO 2.
2.CHECK IPDM E/R
Check voltage between IPDM E/R harness connector and ground
while front wiper motor is stopped and while it is operating.
OK or NG
OK >> Replace IPDM E/R. Refer toPG-26, "Removal and
Installation of IPDM E/R".
NG >> GO TO 3.
