System Description
INFOID:0000000003247141
• Electronic Brake force Distribution detects subtle slippages between front and rear wheels during braking,
and it improves handling stability by electronically controlling brake fluid pressure which results in reduced
rear wheel slippage.
• If the electrical system malfunction, fail-safe function is activated, EBD and ABS becomes inoperative, and
ABS warning lamp and brake warning lamp are turned ON.
• Electrical system diagnosis by CONSULT-III is available.
• During EBD operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
• Just after starting the vehicle after the ignition switch ON, brake pedal may vibrate or motor operating noise
may be heard from engine compartment. This is a normal status of operation check.
• Stopping distance may be longer than that of vehicles without EBD when vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.

FUNCTION
CONSULT-III can display each diagnostic item using the diagnostic test modes as following.
WORK SUPPORT
SELF-DIAGNOSTIC RESULT
Operation Procedure
Before performing the self-diagnosis, start the engine and drive the vehicle at 30 km/h (19 MPH) or more for
approximately 1 minute.
Display Item List
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, the ABS warning lamp,
VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp will not turn OFF even when the sys-
tem is normal unless the vehicle is driving 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 “ON” position.
