POWER DISTRIBUTION SYSTEM

System Description

INFOID:0000000003805720

• PDS (POWER DISTRIBUTION SYSTEM) is the system that BCM controls with the operation of the push-

button ignition switch and performs the power distribution to each power circuit. This system is used instead
of the mechanical power supply changing mechanism with the operation of the conventional key cylinder.

• The push-button ignition switch can be operated when Intelligent Key is in the following condition. Refer to

Engine Start Function for details.

- Intelligent Key is in the detection area of the inside key antenna
- Insert Intelligent Key into the key slot
- Insert key fob into the key slot
• The push-button ignition switch operation is input to BCM as a signal. BCM changes the power supply posi-

tion according to the status and operates the following relays to supply power to each power circuit.

- Ignition relay (built into IPDM E/R)
- Ignition relay (inserted into fuse block)
- ACC relay
- Blower fan relay

NOTE:
The engine switch operation changes due to the conditions of brake pedal, selector lever and vehicle speed.

• The power supply position can be confirmed with the illuminating of the indicators around the push-button

ignition switch.

BATTERY SAVER SYSTEM

When all of the following conditions are met for 60 minutes, the battery saver system will cut off the power sup-
ply to prevent battery discharge.
• The ignition switch is in the ACC position
• All doors are closed
• Selector lever is in the P position

Reset Condition of Battery Saver System

In order to prevent the battery from discharging, the battery saver system will cut off the power supply when all
doors are closed, the selector lever is in the P position and the ignition switch is left in the ACC position for 60
minutes. If any of the following conditions are met the battery saver system is released and the steering will
change automatically to the LOCK position from the OFF position.
• Opening any door
• Operating with door key cylinder on door lock
• Operating with request switch on door lock
• Operating with Intelligent Key on door lock
Press push-button ignition switch and ignition switch will change to the ACC position from the OFF position.

STEERING LOCK OPERATION

Steering is locked by steering lock unit when ignition switch is in the OFF position, selector lever is in the P
position and any of the following conditions are met.
• Opening door
• Closing door
• Door is locked with request switch
• Door is locked with Intelligent Key

PUSH-BUTTON IGNITION SWITCH OPERATION PROCEDURE

The power supply position changing operation can be performed with the following operations.

Operation Enable Condition

• When an Intelligent Key is within the detection area of inside key antenna and when it is inserted into the key

slot, the operation is as per the following.

• When starting the engine, the BCM monitors the following engine start conditions,
- Brake pedal operating condition
- Selector lever position
- Vehicle speed
• Unless each start condition is fulfilled, the engine will not respond regardless of how many times the engine

switch is pressed. At that time, illumination repeats the position in the order of LOCK

→

ACC

→

ON

→

OFF.

Operation Condition

*1: When the selector lever position is in the N position, the engine start condition is different according to the vehicle speed.

• At a vehicle speed of less than 4 km/h (2.5MPH), the engine can start only when the brake pedal is depressed.

• At a vehicle speed of 4 km/h (2.5MPH) or more, the engine can start even if the brake pedal is not depressed. (It is the same as

“Engine stall return operation while driving”.)

*2: When the selector lever position is in any position other than the P position and when the vehicle speed is 5 km/h (3.1MPH) or more,
the engine stop condition is different.

• Press and hold the push-button ignition switch for 2 seconds or more. (When the push-button ignition switch is pressed for too short a

time, the operation may be invalid, so properly press and hold to prevent an incorrect operation.)

• Press the push-button ignition switch 3 times or more within 1.5 seconds. (Emergency stop operation)
