IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE
ROOM)
System DescriptionINFOID:0000000005928343
• IPDM E/R (Intelligent Power Distribution Module Engi ne 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, oil pressure switch signal reception, etc.
• It controls operation of each electrical co mponent via ECM, BCM and CAN communication lines.
CAUTION:
None of the IPDM E/R integr ated 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)
• 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. Rear window defogger relay control Using CAN communication lines, it receives signals from the BCM and controls the rear window defogger
relay.
4. A/C compressor control Using CAN communication lines, it receives signal s from the ECM and controls the A/C compressor
(magnet clutch).
5. Starter control Using CAN communication lines, it receives signals from the BCM and controls the starter relay.
6. Cooling fan control Using CAN communication lines, it receives signals from the ECM and controls the cooling fan relays.
7. Horn control Using CAN communication lines, it receives signals from the BCM and controls the horn relay.
8. Daytime light system control (Canada only) Using CAN communication lines, it receives signals from the BCM and controls the daytime light 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, headlamp low relay is ON, headlamp high relays are OFF, and
daytime light system (Canada only) is OFF.
• With the ignition switch OFF, the headlamp relays are 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.
Cooling fan • With the ignition switch ON, cooling fan relay-1, relay-2, and relay-3 are ON.
• With the ignition switch OFF, all cooling fan relays are OFF.
Front wiper Until the ignition switch is turned off, the front wiper relays remain in the same status they
were in just before fail
−safe control was initiated.

ACTIVE TEST
Display Item List
Auto Active TestINFOID:0000000005928347
DESCRIPTION
• In auto active test mode, operation inspection can be performed when IPDM E/R sends a drive signal to the
following systems:
- Rear window defogger
- Front wipers
- Tail, license and parking lamps
- Daytime lamp system (Canada only)
- Front fog lamps
- Headlamps (High, Low)
- A/C compressor (magnet clutch)
- Cooling fan
OPERATION PROCEDURE
1. Close hood and front door RH, and lift wiper arms away from windshield (to prevent glass damage by wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn ignition switch OFF.
3. Turn ignition switch ON and, within 20 seconds, pres s front door switch LH 10 times. Then turn ignition
switch OFF.
4. Turn ignition switch ON within 10 seconds after ignition switch OFF.
5. When auto active test mode is actuated, horn chirps once.
6. After a series of operations is repeated three times, auto active test is completed.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
Concept of Auto Active Test
• IPDM E/R actuates auto active test mode when it re ceives door switch signal from BCM via CAN communi-
cation line. Therefore, when auto active test mode is activated successfully, CAN communication between
IPDM E/R and BCM is normal.
• If any of the systems controll ed by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.
