PDU (POWER DISTRIBUTION UNIT)
Revision: 2007 April2007 M35/M45
PDU (POWER DISTRIBUTION UNIT)PFP:285F1
Component Parts and Harness Connector LocationNKS004ED
System DescriptionNKS004EE

PDU (Power Distribution Unit) is the unit that executes the power distribution with the control signal from
the Intelligent Key unit, instead of the mechanical power supply mechanism by conventional key cylinder.

The push-button ignition switch is operable when the Intelligent Key is within the detention area of the
interior antenna or is inserted to the key slot.

The push-button ignition switch operation is input to the Intelligent Key unit as a request signal. Then, the
Intelligent Key unit processes the request signal and orders the PDU to switch into the appropriate power
supply position.
NOTE:
The prerequisite for starting the engine varies by the state of brake pedal, A/T selector lever, and vehicle
speed.

PDU distributes power to each power supply circuit according to the request signal received.

The power supply position can be confirmed by illumination of the indicators in the upper surroundings of
the push-button ignition switch.
PUSH-BUTTON IGNITION SWITCH OPERATING PROCEDURE
The power supply position switching operation can be performed by the following operation.
NOTE:

When an Intelligent Key is within the detection area of inside antenna and when it is inserted to the key
slot, it is equivalent to the operations below.

When starting the engine, the Intelligent Key unit monitors the engine start conditions (brake pedal operat-
ing condition, A/T selector lever position, and vehicle speed).

FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationNKS003WB
System DescriptionNKS003WC

Front wiper relays (HIGH, LOW) are included in IPDM E/R (intelligent power distribution module engine
room).

Front wiper reverse relay is included in relay box-1. Refer to PG-98, "ELECTRICAL UNITS LOCATION" .

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 (body control module) 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.

Front wiper motor switches LOW speed to/from HIGH speed by BCM function to change polarity.
OUTLINE
Power is supplied at all times

to ignition relay, located in IPDM E/R, from battery directly,

through 50 A fusible link (letter F, located in fuse and fusible link block)

to BCM terminal 55,

through 10 A fuse [No. 21, located in fuse block (J/B)]

to BCM terminal 42,

through 30 A fuse (No. 73, located in IPDM E/R)

to front wiper low relay, located in IPDM E/R
