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).
