OUTLINE
• BCM (body control module) controls various electric al components. It receives the information required from
CAN communication and the signals received from each switch and sensor.
• BCM has a combination switch reading function for readi ng the status of combination switches (light, turn
signal, wiper and washer) in addition to functions for c ontrolling the operation of various electrical compo-
nents. It also has a signal transmission function for ot her systems, and a power consumption control function
that reduces the power consumpt ion with the ignition switch OFF.
• BCM is equipped with a diagnosis function that operates with CONSULT and allows for various settings to
be changed.

• BCM reads the status of the combination switch (light, turn signal, wiper and washer) and recognizes the
status of each switch.
• BCM has a combination of 5 output terminals (OUTPU T 1 - 5) and 5 input terminals (INPUT 1 - 5) and reads
a maximum of 20 switch states.

• BCM receives the sleep-ready signal (ready) from IPDM E/R and combination meter via CAN communica-
tion.
• BCM transmits the sleep wake up signal (sleep) to each unit when all of the CAN sleep conditions are ful-
filled.
• Each unit stops the transmission of CAN communication with the sleep wakeup signal. BCM is in CAN com- munication sleep mode.
• BCM is in the low power consumption mode and performs the low power consumption control when all of the
BCM sleep conditions are fulfilled with CAN sleep condition.
Sleep condition
Wake-up operation
• BCM changes from the low power consumption m ode to the CAN communication sleep mode when the any
of the BCM wake-up conditions are fulfilled. Only the control with BCM is activated.
• BCM transmits the sleep wake up signal (wake up) to each unit when any of the CAN wake-up conditions are fulfilled. It changes from the low power consum ption mode or the CAN communication sleep mode to the
normal mode.
• Each unit starts the transmission of CAN communicati on with the sleep wake up signal. In addition, the com-
bination meter transmits the wake up signal to BCM via CAN communication to report the CAN communica-
tion start.

CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and a no-start condition.
APPLICATION ITEM
CONSULT performs the following functions via CAN communication with BCM.
