POWER DISTRIBUTION SYSTEM

System Description


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 interior antenna
- Insert Intelligent Key in to the key slot
- The push-button ignition switch operation is input to BCM as a signal. BCM changes the power supply position according to the status and operates the following relays to supply power to each power circuit.
- Ignition relay (inside IPDM E/R)
- Ignition relay (inside fuse block)
- ACC relay
- Blower relay
- The power supply position changes due to the conditions of push-button ignition switch operation, brake pedal, clutch pedal, selector lever and vehicle speed.
NOTE:
The power supply position can be confirmed with the lighting of the indicators near the push-button ignition switch.

BATTERY SAVER SYSTEM

When all the following conditions are met for 60 minutes, the battery saver system will cut off the power supply 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
If any of the following conditions are met the battery saver system is released.
- Opening any door
- Operating with door request switch on door lock
- Operating with Intelligent Key on door lock
- Change ignition switch position to ACC position from OFF position by pressing push-button ignition switch.

POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERATION

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 it is inserted to the key slot, it is equivalent to the operations below.
- When starting the engine, the BCM monitors under the engine start conditions,
A/T 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
