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.
Opening any door
Operating with door request switch on door lock
Operating with Intelligent Key on door lock
Press push-button ignition switch and ignition swit ch will change to ACC position from OFF position.

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 door request switch
Door is locked with Intelligent Key
POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERA-
TION
The power supply position changing operation can be performed with the following operations.
NOTE:
When an Intelligent Key is within the detection area of inside key antenna and when Intelligent Key backside
is contacted to push-button ignition switch, it is equivalent to the operations below.
When starting the engine, the BCM monitors under the engine start conditions,
- Brake pedal operating condition
- Selector lever position
- Vehicle speed
Vehicle speed: less than 4 km/h (2.5 MPH)
Vehicle speed: 4 km/h (2.5 MPH) or more

DescriptionINFOID:0000000006220228
Check that vehicle is under the condition shown in “C onditions of vehicle” before starting diagnosis, and check
each symptom.
NOTE:
The engine start function, door lock function, power dist ribution system, and NATS-IVIS/NVIS in the Intelligent
Key system are closely related to each other regarding c ontrol. The vehicle security function can operate only
when the door lock and power distribution system are operating normally.
Conditions of Vehicle (Operating Conditions)
“ENGINE START BY I-KEY” in “WORK SUPPOR T” is ON when setting on CONSULT-III.
One or more of Intelligent Keys with registered Intelligent Key ID is in the vehicle.
Diagnosis ProcedureINFOID:0000000006220229
1.PERFORM WORK SUPPORT
Perform “INSIDE ANT DIAGNOSIS” on Wo rk Support of “INTELLIGENT KEY”.
Refer to DLK-41, "
INTELLIGENT KEY : CONSULT-III Function (BCM - INTELLIGENT KEY)".
>> GO TO 2.
2.PERFORM SELF-DIAGNOSIS RESULT
Perform Self-Diagnosis Result of “BCM”.
Is DTC detected?
YES >> Refer to BCS-57, "DTCIndex".
NO >> GO TO 3.
3.CHECK PUSH-BUTTON IGNITION SWITCH
Check push-button ignition switch.
Refer to PCS-71, "
ComponentFunctionCheck".
Is the operation normal?
YES >> GO TO 4.
NO >> Repair or replace malfunctioning parts.
4.CONFIRM THE OPERATION
Confirm the operation again.
Is the inspection normal?
