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. 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-1 Ignition relay-2 Accessory relay-1 Accessory relay-2 Blower motor 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 lighting of the indicators in the push-button ignition switch.
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

Refer to " CAN COMMUNICATION SYSTEM: SYSTEM DESCRIPTION ".
Check that vehicle Operating Conditions are as listed in "Conditions of Vehicle" below before starting Diagnosis Procedure. Make sure to check each symptom in Diagnosis Procedure.
Note. The engine start function, door lock function, power distribution system, and NATS-NVIS in the Intelligent Key system are closely related to each other regarding control. The vehicle security function can operate only when the door lock and power distribution system are operating normally.
