< SYSTEM DESCRIPTION >
[POWER DISTRIBUTION SYSTEM]
COMPONENT PARTS
BCM compares following status comparing.
• Ignition relay-1 control signal, and power supply position judged by BCM
• Ignition relay (inside IPDM E/R) control request, and Ignition relay (inside IPDM E/R) status
Accessory Relay
INFOID:0000000006220193
BCM turns ON the accessory relays to supply accessory power supply or ignition switch ACC signal to each
ECU when the ignition switch is turned ACC or ON.

BCM turns ON the following relays to supply ignition power supply or ignition switch ON signal to each ECU
when the ignition switch is turned ON.
• Ignition relay-1
• Ignition relay (inside IPDM E/R)
• Blower relay
BCM compares status of blower relay control signal, and power supply position judged by BCM.
Push-Button Ignition Switch
INFOID:0000000006220195
