For malfunction of ABS, only the EBD is activated and the condition of vehicle is the same condition of vehi-
cles without ABS system.
NOTE:
ABS self-diagnosis sound may be heard. That is a normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.
For malfunction of EBD, EBD and ABS become inoperative, and the condition of vehicle is the same as the
condition of vehicles without ABS, EBD system.

Diagnosis ProcedureINFOID:0000000003766852
1.CHECK START
Check front and rear brake force distribution using a brake tester. Refer to BR-45, "
General Specifications".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Check brake system.
2.CHECK FRONT AND REAR AXLE
Make sure that there is no excessive play in the front and rear axles.
Front: Refer to FA X - 6 , "
Inspection".
Rear: Refer to RAX-3, "
Inspection".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace malfunctioning components.
3.CHECK WHEEL SENSOR AND SENSOR ROTOR
Check the following.
Wheel sensor installation for damage.
Sensor rotor installation for damage.
Wheel sensor connector connection.
Wheel sensor harness inspection.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Replace wheel sensor or sensor rotor.
Repair harness.
4.CHECK ABS WARNING LAMP DISPLAY
Make sure that the ABS warning lamp is turned off after the ignition switch is turned ON or when driving.
Is the ABS warning lamp illuminated?
YES >> Perform self-diagnosis.
NO >> Normal

UNEXPECTED PEDAL REACTION
Diagnosis ProcedureINFOID:0000000003766853
1.CHECK BRAKE PEDAL STROKE
Check brake pedal stroke. Refer to BR-6, "
Inspection and Adjustment".
Is the stroke too large?
YES >> Bleed air from brake tube and hose. Refer to BR-10, "Bleeding Brake System".
Check brake pedal, brake booster, and master cylinder for mount play, looseness, brake system
fluid leakage, etc.
- Brake pedal: Refer to BR-6, "
Inspection and Adjustment".
- Brake booster: Refer to BR-12, "
Inspection".
- Brake master cylinder: Refer to BR-11, "
Inspection".
NO >> GO TO 2.
2.CHECK FUNCTION
Disconnect ABS actuator and electric unit (control unit) connector to deactivate ABS. Check if braking force is
normal in this condition. Connect connector after inspection.
Is the inspection result normal?
YES >> Normal
NO >> Check brake system.
