Description |
| 1. |
Push-button ignition switch1 |
Push-button ignition switch (push switch) is pressed (ON), and transmits status signal to BCM and IPDM E/R. |
| Ignition switch2 |
Ignition switch is turned to ON, and transmits status signal to BCM and IPDM E/R. |
| 2. |
IPDM E/R |
- IPDM E/R detects push-button ignition switch 1 or ignition switch2
status, and transmits 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)
|
| 3. |
BCM |
- BCM controls power distribution system.
- BCM judges ignition position and vehicle condition.
- BCM checks ignition position internally.
|
| 4. |
Ignition relay-2 (in fuse block) |
- Ignition relay-2 is controlled by BCM.
- Ignition relay-2 supplies ignition ON power supply or ignition ON signal to each ECU and system when ignition is turned ON.
- BCM compares status of ignition relay-2 control signal and ignition position judged by BCM.
- BCM monitors ignition relay-2 operating status by ignition relay-2 feedback signal.
|
| 5. |
Front blower motor relay (in fuse block) |
- Front blower motor relay is controlled by BCM.
- Front blower motor supplies ignition ON power supply or ignition ON signal to air conditioning system when ignition is turned ON.
- BCM compares status of front blower motor relay control signal and ignition 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 ON signal to each ECU when ignition is turned ON.
- BCM compares status of accessory relay-1 control signal, and ignition position judged by BCM.
