IPDM E/R | - Controls the integrated smart FET, and supplies voltage to the load according with the request from BCM via CAN communication.
- Transmits the control signal and request (via LIN communication) to the load according with the request from BCM via CAN communication.
|
BCM | - Detects each switch condition by the combination switch reading function.
- Exterior light ON/OFF is judged from each signal, and then a request is transmitted to IPDM E/R (via CAN communication) to turn controls the each lamps.
- It also transmits a status to the combination meter (via CAN communication) to turns indicator light ON/OFF.
|
Combination meter | Turns the indicator light ON/OFF or displays the indicator according to the status from BCM via CAN communication. |
Front door switch (driver side) | Detects the front door condition (open or close), and inputs the door switch signal to BCM. |
Keyless operation key unit | Transmits the door lock request signal to BCM (via CAN communication) from door lock button operation. |
ECM | ECM transmits engine status signal to BCM via CAN communication. |
Combination switch | Lighting & turn signal switch | Inputs the each switch condition signal to BCM. |
