• 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 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.

BRAKE BOOSTER
InspectionINFOID:0000000009463686
OPERATION
Depress the brake pedal several times at five second intervals with
the engine stopped. Start the engine with the brake pedal fully
depressed. Check that the cl earance between brake pedal and dash
lower panel decreases.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. Th is is normal brake system opera-
tion.
VACUUM INSPECTION
Idle the engine for one minute to apply vacuum to the brake booster.
Stop the engine. Depress the brake pedal several times at five sec-
ond intervals until the accumulated vacuum is released to atmo-
spheric pressure. Check that the clearance between brake pedal
and dash lower panel gradually increases (A → B → C) each time
the brake pedal is depressed during this operation.
Depress the brake pedal with the engine running. Then stop the
engine while holding down the brake pedal. Check that the brake
pedal stroke does not change after holding down the brake pedal for
30 seconds or more.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. Th is is normal brake system opera-
tion.

CONSULT Function (ABS)INFOID:0000000009463758
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”, potentiall y causing a discharged battery and a no-start condition.
FUNCTION
CONSULT can display each diagnostic item us ing the following direct diagnostic modes.
ECU IDENTIFICATION
ABS actuator and electric unit (control unit) part number is displayed.
SELF DIAGNOSTIC RESULT
Operation Procedure
1. Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for
approximately 1 minute.
How To Erase Self Diagnostic Result
1. After erasing DTC memory, start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute as the final inspection, and make sure t hat the ABS warning lamp, VDC OFF indicator lamp,
SLIP indicator lamp and brake warning lamp turn OFF.
CAUTION:
If memory cannot be erased, perform applicable diagnosis.
NOTE:
• When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning lamp,
SLIP indicator lamp and brake warning lamp will not turn OFF even when the system is normal, unless
the vehicle is driven at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
• Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake fluid
level switch operation (when brake fluid is insufficient).
• VDC OFF switch should not stay in ON position.
Display Item List
Refer to BRC-45, "DTC Index".
