Electric Brake force Distribution is a following function. ABS actuator and electric unit (control unit) detects
subtle slippages between the front and rear wheels during braking. Then is electronically controls the rear
braking force (brake fluid pressure) to reducing and reduces rear wheel slippage. Accordingly it improves
vehicle stability.
Electrical system diagnosis by CONSULT-III is available.

FUNCTION
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
WORK SUPPORT
SELF DIAGNOSTIC RESULT
Operation Procedure
Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for approxi-
mately 1 minute.
Display Item List
Refer to BRC-140, "DTC No. Index".
How to Erase Self-diagnosis Results
After erasing DTC memory, start the engine and drive the vehicle at 30 km/h (19 MPH) or more for approxi-
mately 1 minute as the final inspection, and make sure that 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, ABS warning lamp, VDC
OFF indicator 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 in case of brake
fluid level switch operation (when brake fluid is insufficient).
VDC OFF switch should not stay in “ON” position.

Diagnostic test mode Function
Work supportThis mode enables a technician to adjust some devices faster and more accurately by following
the indications on CONSULT-III.
Self diagnostic result Self-diagnostic results can be read and erased quickly.
Data monitor Input/Output data in the ABS actuator and electric unit (control unit) can be read.
Active testCONSULT-III drives some actuators apart from ABS actuator and electric unit (control unit) and
also shifts some parameters in a specified range.
ECU identification ABS actuator and electric unit (control unit) part number can be read.

ACTIVE TEST
CAUTION:
Do not perform active test while driving vehicle.
Make sure to completely bleed air from brake system.
The active test cannot be started when ABS warning lamp, VDC OFF indicator lamp, SLIP indicator
lamp and brake warning lamp are ON.
ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp are ON
during active test.
NOTE:
When active test is performed while depressing the pedal, the pedal depression amount will change. This is
normal. (Only solenoid valve and ABS motor.)
“TEST IS STOPPED” is displayed 10 seconds after operation start.
After “TEST IS STOPPED” is displayed, to perform test again.
