System Description

INFOID:0000000005275044

• 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 it electronically controls the rear
braking force (brake fluid pressure) to reduce rear wheel slippage. Accordingly, it improves vehicle stability.

• Electrical system diagnosis by CONSULT-III is available.

CONSULT-III Function (ABS)

INFOID:0000000005275047

FUNCTION

CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.

SELF DIAGNOSTIC RESULT MODE

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-diagnosis Results

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 that the ABS warning 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

and brake warning lamp will not turn OFF even when the system 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).
