[POWER DISTRIBUTION SYSTEM]

COMPONENT PARTS

BCM compares following status comparing.

• Ignition relay (fuse block) control signal, and power supply position judged by BCM

• Ignition relay (IPDM E/R) control request, and Ignition relay (IPDM E/R) status

Accessory Relay

INFOID:0000000012197183

BCM turns ON the accessory relays to supply accessory power supply or ignition switch ACC signal to each

ECU when the ignition switch is turned ACC or ON.

BCM compares status of accessory relay control signal, and power supply position judged by BCM.

Blower Relay

INFOID:0000000012197184

BCM turns ON the following relays to supply ignition power supply or ignition switch ON signal to each ECU

when the ignition switch is turned ON.

• Ignition relay (fuse block)

• Ignition relay (IPDM E/R)

• Blower relay

BCM compares status of blower relay control signal, and power supply position judged by BCM.

Push-Button Ignition Switch

INFOID:0000000012197185

BCM transmits the change in the power supply position with the push-button ignition switch to IPDM E/R via

CAN communication line. IPDM E/R transmits the power supply position status via CAN communication line to

BCM.

Stop Lamp Switch

INFOID:0000000012197186

Stop lamp switch detects that brake pedal is depressed, and then transmits the signal to BCM.

Transmission Range Switch

INFOID:0000000012197187

Transmission range switch is integrated in CVT assembly, and detects the CVT shift selector position.

Transmission range switch detects selector lever position (P/N position), and transmits the P/N position signal

to BCM.

Clutch Interlock Switch

INFOID:0000000012197188

Clutch interlock switch detects that clutch pedal is depressed, and transmits ON/OFF signal to BCM.

POWER DISTRIBUTION SYSTEM : System Description

INFOID:0000000012197190

SYSTEM DESCRIPTION

• 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.

- Intelligent Key backside is contacted to push-button ignition switch.

• 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 (IPDM E/R)

- Ignition relay (fuse block)

- ACC relay

- Blower relay

NOTE:

The push-button ignition switch operation changes due to the conditions of brake pedal, selector lever and

vehicle speed.

• The power supply position can be confirmed with the lighting of ACC/ON indicator in the push-button ignition

switch.

IGNITION BATTERY SAVER SYSTEM

Ignition Position [ON]

When all the following conditions are met for 10 minutes, the battery saver system will cut off the power supply

(ignition switch position ON 

→

 OFF) to prevent battery discharge.

Ignition Position [ACC]

When all the following conditions are met for 30 minutes, the battery saver system will cut off the power supply

(ignition switch position ACC 

→

 OFF) to prevent battery discharge.

• Ignition switch is in the ACC position

• Turn signal lamp is not in operation

• Selector lever is in the P position

Reset Condition of Ignition Battery Saver System

If any of the following conditions are met the battery saver system is released.

• Ignition switch is not in the ACC/ON position.

• Selector lever is not in the P position.

POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERA-
TION

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

NOTE:

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

is contacted to push-button ignition switch, it is equivalent to the operations below.

• When starting the engine, the BCM monitors under the engine start conditions,

CVT models

- Brake pedal operating condition

- Selector lever position

- Vehicle speed

M/T models

- Clutch pedal operating condition

- Vehicle speed

Vehicle speed: less than 4 km/h (2.5 MPH)

Vehicle speed: 4 km/h (2.5 MPH) or more

Emergency stop operation
• Press and hold the push-button ignition switch for 2 seconds or more.
• Press the push-button ignition switch 3 times or more within 1.5 seconds.

REAR WIPER MOTOR PROTECTION

BCM detects the rear wiper stopping position according to the rear wiper stop position signal.

When the rear wiper stop position signal does not change for more than 5 seconds while driving the rear

wiper, BCM stops power supply to protect the rear wiper motor.

Condition of cancellation

1. More than 1 minute is passed after the rear wiper stop.

2. Turn rear wiper switch OFF.

3. Operate the rear wiper switch or rear washer switch.

FAIL-SAFE CONTROL OF COMBINATION SWITCH READING FUNCTION CAUSED BY LOW
POWER SUPPLY VOLTAGE

If voltage of battery power supply lower, BCM maintains combination switch reading to the status when input

voltage is less than approximately 9 V.

NOTE:

When voltage of battery power supply is approximately 9 V or more, combination switch reading function

returns to normal operation.
