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 ignition switch position according to the status and operates the following relays to supply power to each power circuit. Ignition relay (IPDM E/R) Ignition relay [fuse block (J/B)] Accessory relay Blower relay
- The ignition switch position can be confirmed with the lighting of the LOCK/ACC/ON indicator lamp in the push-button ignition switch.
Refer to " INTELLIGENT KEY SYSTEM/ENGINE START FUNCTION: SYSTEM DESCRIPTION ".

Check that vehicle is under the condition shown in "Conditions of vehicle" before starting diagnosis, and check each symptom.
Note. The engine start function, door lock function, power distribution system, and NATS-IVIS/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.
- Before performing the diagnosis in the following table, check "Work Flow". Refer to " «WORK FLOW»(ref-672673-S06607539552014112400000) ".
