POWER DISTRIBUTION SYSTEM

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
- Insert Intelligent Key into 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 (built into IPDM E/R)
- Ignition relay (inserted into 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 of 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 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.

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 or 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 (Right Arrow) ACC (Right Arrow) ON (Right Arrow) OFF.
