CAUTION:

Oil filter is provided with relief valve. Use genuine NIS-
SAN engine oil filter or equivalent.

When removing, prepare a shop cloth to absorb any
engine oil leakage or spillage.

Do not allow engine oil to adhere to drive belts.

Completely wipe off any engine oil that adhere to engine
and vehicle.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
Revision: 2007 April2007 M35/M45
IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionNKS004E2

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.

IPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control and
oil pressure 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, it receives signal from BCM and controls the following lamps:

Headlamps (HI, LO)

Tail, parking and license plate lamps

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

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
Headlamps

With the ignition switch ON, the headlamp low relay is ON.

With the ignition switch OFF, the headlamp low relay is OFF.
Tail, parking and
license plate 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, 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.
