Normal status
• When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10ms.
Sleep status
• When BCM is in sleep mode, transistors of OUTPUT 1 and 5 stop the output, and BCM enters low-cur-
rent-consumption mode. OUTPUTS (2, 3, and 4) turn ON-OFF at 60ms intervals, and receives lighting
switch input only.
CAN COMMUNICATION CONTROL
CAN communication allows a high rate of information through the two communication lines (CAN-L, CAN-H)
connecting the various control units in the system. Each control unit transmits/receives data, but selectively
reads required data only.
BCM STATUS CONTROL
BCM changes its status depending on the operation status in order to save power consumption.
1. CAN communication status
• With ignition switch ON, CAN communicates with other control units normally.
• Control by BCM is being operated properly.
• When ignition switch is OFF, switching to sleep mode is possible.
• Even when ignition switch is OFF, if CAN communication with IPDM E/R and combination meter is
active, CAN communication status is active.
2. Sleep transient status
• This status shuts down CAN communication when ignition switch is turned OFF.
• It transmits sleep request signal to IPDM E/R and combination meter.
• Two seconds after CAN communication of all control units stops, CAN communication switches to inac-
tive status.
3. CAN communication inactive status
• With ignition switch OFF, CAN communication is not active.
• With ignition switch OFF, control performed only by BCM is active.
• Three seconds after CAN communication of all control units stops, CAN communication switches to
inactive status.
4. Sleep status
• BCM is activated with low current consumption mode.
• CAN communication is not active.

BCM (BODY CONTROL MODULE)
• When CAN communication operation is detected, it switches to CAN communication status.
• When a state of the following switches changes, it switches to CAN communication state:
- Ignition switch
- Key switch (without Intelligent Key)
- Key switch and ignition knob switch (with Intelligent Key)
- Hazard switch
- Door lock/unlock switch
- Front door switch (LH, RH)
- Rear door switch (LH, RH)
- Back door lock assembly (Hatchback)
- Trunk key cylinder switch (Sedan)
- Trunk lamp switch and trunk release solenoid (Sedan)
- Combination switch (passing, lighting switch 1st position, front fog lamp)
- Keyfob (lock/unlock signal)
- Front door key cylinder switch LH
• When control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.
• Status of combination switch reading function is changed.
