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)
- Accessory relay
- Blower relay
- The power supply potision changes due to the conditions of push-button ignition switch operation, brake 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.
- For models without sterring lock unit, power supply position changes from "OFF" to "LOCK" when steering lock conditions are satisfied.
