HIGH FLASHER OPERATION
BCM detects the turn signal lamp circuit status by the current value.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.

POWER DISTRIBUTION SYSTEM
FUNCTION DIAGNOSIS
POWER DISTRIBUTION SYSTEM
System DescriptionINFOID:0000000003805720
 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
- Insert key fob into the key slot
 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 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 fan 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 illuminating of the indicators around 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 sup-
ply 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 in the P position and the ignition switch is left in the ACC position for 60
minutes. 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.
STEERING LOCK OPERATION
Steering is locked by steering lock unit when ignition switch is in the OFF position, selector lever is in the P
position and any of the following conditions are met.
 Opening door
 Closing door
 Door is locked with request switch
 Door is locked with Intelligent Key
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 and 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→ACC→ON→OFF.
