IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionEKS00JLJ
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 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 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
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 signals 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 wiperUntil 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.
