  • Accessory relay-2 supplies accessory power supply or ignition switch ACC signal to each ECU when ignition switch is turned to ACC or ON.
  • BCM compares status of accessory relay-2 control signal, and ignition switch position judged by BCM.
2. BCM
  • BCM controls power distribution system.
  • BCM judges ignition switch position by push-button ignition switch (push switch) and vehicle condition.
  • BCM checks ignition switch position internally.
3. Push-button ignition switch Push-button ignition switch (push switch) is pressed, and transmits status signal to BCM and IPDM E/R.
4. IPDM E/R
  • IPDM E/R detects push-button ignition switch (push switch) status, and transmits push-button ignition switch status signal (CAN) to BCM.
  • IPDM E/R receives ignition relay-1 (IPDM E/R) control signal and ignition switch ON signal (CAN) from BCM, and controls ignition relay-1 (built into IPDM E/R)
5. Blower relay (in fuse block)
  • Blower relay is controlled by BCM.
  • Blower relay supplies ignition switch ON power supply or ignition switch ON signal to air conditioning system when ignition switch is turned ON.
  • BCM compares status of blower relay control signal and ignition switch position judged by BCM.
6. Accessory relay-1 (in fuse block)
  • Accessory relay-1 is controlled by BCM.
  • Accessory relay-1 supplies accessory power supply or ignition switch ACC signal to each ECU when ignition switch is turned ACC or ON.
  • BCM compares status of accessory relay-1 control signal, and ignition switch position judged by BCM.
7. Ignition relay-2 (in fuse block)
  • Ignition relay-2 is controlled by BCM.
  • Ignition relay-2 supplies ignition switch ON power supply or ignition switch ON signal to each ECU and system when ignition switch is turned ON.
  • BCM compares status of ignition relay-2 control signal and ignition switch position judged by BCM.
  • BCM monitors ignition relay-2 operating status by ignition relay feedback signal.
