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