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, sleep transient status switches to CAN
communication inactive 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 inactive status
switches to sleep status.
4. Sleep status

BCM is activated with low power mode.

CAN communication is not active.

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.
–Key switch (ACC, ON)
–Hazard switch
–Door lock/unlock switch
–Front door switch (driver side, passenger side)
–Back door opener switch (coupe models)
–Trunk lid opener switch (roadster models)
–Combination switch (passing, lighting switch 1ST position)
–Key fob (lock/unlock signal)
–Key cylinder switch

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.
