BODY CONTROL SYSTEM
: System DescriptionINFOID:0000000009461989
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.

COMBINATION SWITCH READING FUNCTION
Description
• BCM reads the status of the combinat
ion switch at 10 ms intervals normally.
NOTE:
BCM reads the status of the combination switch at 60 ms intervals when BCM is controlled at low power
consumption control mode.
• BCM operates as follows and judges the status of the combination switch.
- It operates the transistor on OUTPUT si de in the following order: OUTPUT 1 → 2 → 3 → 4 → 5, and outputs
voltage waveform.
- The voltage waveform of OUTPUT corresponding to the formed circuit is input into the interface on INPUT
side if any (1 or more) switches are ON.

COMMON ITEM
COMMON ITEM : CONSULT Fu
nction (BCM - COMMON ITEM)INFOID:0000000009461996
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.
SYSTEM APPLICATION
BCM can perform the following functions.
Direct Diagnostic Mode Description
Ecu Identification The BCM part number is displayed.
Self Diagnostic Result The BCM self diagnostic results are displayed.
Data Monitor The BCM input/output data is displayed in real time.
Active Test The BCM activates outputs to test components.
Work support The settings for BCM functions can be changed.
Configuration • The vehicle specification can be read and saved.
• The vehicle specification can be written when replacing BCM.
CAN Diag Support Mntr The result of transmit/receive diagnosis of CAN communication is displayed.

PEDAL VIBRATION OR ABS OPERATION SOUND OCCURS
Diagnosis ProcedureINFOID:0000000009463843
CAUTION:
Under the following conditions, ABS is activated an d vibration is felt when brake pedal is lightly
depressed (just place a foot on i t). However, this is normal.
• When shifting gears
• When driving on slippery road
• During cornering at high speed
• When passing over bumps or grooves [approximately 50 mm (1.97 in) or more]
• When pulling away just after starting engine [a t approximately 10 km/h (6 MPH) or higher]
1.SYMPTOM CHECK 1
Check that there are pedal vibrat ions when the engine is started.
Do symptoms occur?
YES >> GO TO 2
NO >> Inspect the brake pedal.
2.SYMPTOM CHECK 2
Check that there are ABS operati on noises when the engine is started.
Do symptoms occur?
YES >> GO TO 3
NO >> Perform self diagnostic result. Refer to BRC-33, "CONSULT Function (ABS)"
.
3.SYMPTOM CHECK 3
Check symptoms when electrical component (headlamps, etc.) switches are operated.
Do symptoms occur?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit. If there is,
move it farther away.
NO >> Inspection End.
