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 distributi on to each power circuit. This system is used instead
of the mechanical power supply changing mechanism wit h 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 contact ed 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 follo wing relays to supply power to each power circuit.
- Ignition relay (inside IPDM E/R)
- Ignition relay-1
- ACC relay
- Blower relay
NOTE:
The engine switch operation changes due to the conditions of brake pedal, selector lever and vehicle speed.
 The power supply position can be confirmed with the light ing 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
In order to prevent the battery from discharging, the battery saver system will cut off the power supply when all
doors are closed, the selector lever is on P position and t he ignition switch is left on ACC position for 1 hour. If
any of the following conditions are met the battery saver system is released and the steering will change auto-
matically to lock position from OFF position.
