EXCESSIVE ABS FUNCTION OPERATION FREQUENCY

Diagnosis Procedure

INFOID:0000000005275376

1.

CHECK START

Check front and rear brake force distribution using a brake tester.
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. Refer to front: 

FAX-5, "On-Vehicle

Inspection and Service"

, Rear: 

RAX-6, "Rear Axle Bearing"

 (C200) or 

RAX-18, "Rear Axle Bearing"

 (M226).

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. Refer to 

BRC-298, "Removal and Installation"

 or 

BRC-

299, "Removal and Installation"

.

• 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?

UNEXPECTED PEDAL REACTION

UNEXPECTED PEDAL REACTION

Diagnosis Procedure

INFOID:0000000005275377

1.

CHECK BRAKE PEDAL STROKE

Check brake pedal stroke. Refer to 

BR-19, "Inspection and Adjustment"

.

Is the stroke too large?

YES

>> • Bleed air from brake tube and hose. Refer to 

BR-21, "Bleeding Brake System"

.

• Check brake pedal, brake booster, and master cylinder for mount play, looseness, brake system

fluid leakage, etc. Refer to 

BR-19, "Inspection and Adjustment"

 (brake pedal), 

BR-12, "On

Board Inspection"

 (master cylinder), 

BR-10, "Inspection"

 (brake booster).

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.
