System Description
- PDS (POWER DISTRIBUTION SYSTEM) is the system that BCM controls with the operation of the pushbutton 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.
- 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 position 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)
- Accessory 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.
- Refer to the following for details at the power supply position.
- LOCK: Ignition switch OFF with steering is locked.
- OFF: Ignition switch OFF with steering is unlocked.
- ACC: Ignition switch ACC
- IGN: Ignition switch ON (Not vehicle condition REDEY)
- RUN: Ignition switch ON (Vehicle condition READY or running)
- CRANKING: Shifting to vehicle condition READY (Transmitting the READY signal from BCM to HPCM)NOTE:
- The power supply position can be confirmed with the lighting of the indicators near the push-button ignition switch.
- For models without steering lock unit, power supply position changes from "OFF" to "LOCK" when steering lock conditions are satisfied.
