BCM STATUS CONTROL
BCM changes its status depending on the operation status in order to save power consumption.
1. CAN communication status
lWith ignition switch ON, CAN communicates with other control units normally.
lControl by BCM is being operated properly.
lWhen ignition switch is OFF, switching to sleep mode is possible.
lEven 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
lThis status shuts down CAN communication when ignition switch is turned OFF.
lIt transmits sleep request signal to IPDM E/R and combination meter.
lTwo seconds after CAN communication of all control units stops, CAN communication switches to inac-
tive status.
3. CAN communication inactive status
lWith ignition switch OFF, CAN communication is not active.
lWith ignition switch OFF, control performed only by BCM is active.
lThree seconds after CAN communication of all control units stops, CAN communication switches to
inactive status.
4. Sleep status
lBCM is activated with low current consumption mode.
lCAN communication is not active.
lWhen CAN communication operation is detected, it switches to CAN communication status.
lWhen a state of the following switches changes, it switches to CAN communication state:
–Key switch
–Hazard switch
–Door lock/unlock switch
–Front door switch (driver side, passenger side)
–Rear door switch (LH, RH) (double cab)
–Rear door switch (driver side, passenger side) No.1 (king cab)
–Rear door switch (driver side, passenger side) No.2 (king cab)
–Combination switch (passing, lighting switch 1st position, front fog lamp)
–Keyfob (lock/unlock signal)
–Door lock assembly LH (key cylinder switch)
lWhen control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.
lStatus of combination switch reading function is changed.

2. Check the current need for scheduled maintenance, especially for fuel filter and air cleaner filter. Refer to
MA-8, "
PERIODIC MAINTENANCE".
3. Open engine hood and check the following:
–Harness connectors for improper connections
–Vacuum hoses for splits, kinks, or improper connections
–Wiring for improper connections, pinches, or cuts
4. Start engine and warm it up to the normal operating tempera-
ture.
>> GO TO 2.
2.PREPARATION FOR CHECKING IDLE SPEED
With CONSULT-II
