Inspection Procedure
1. CHECK CONNECTOR
1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector and steer-
ing angle sensor connector. Check terminal for deformation, disconnection, looseness, and so on. If any
malfunction is found, repair or replace terminal.
2. Securely reconnect connectors and perform self-diagnosis.
Is above displayed in the self-diagnosis item?
YES >> Print out self-diagnostic results and go to LAN-49, "CAN System Specification Chart" .
NO >> Connector terminal connection is loose, damaged, open or shorted.

TROUBLE DIAGNOSIS FOR SYMPTOMS

TROUBLE DIAGNOSIS FOR SYMPTOMSPFP:00007
Excessive ABS Function Operation FrequentlyBFS000EK
1. CHECK START
Check longitudinal brake force distribution using a brake tester. Refer to BR-40, "
SERVICE DATA AND SPEC-
IFICATIONS (SDS)" .
OK or NG
OK >> GO TO 2.
NG >> Check brake system.
2. CHECK FRONT AND REAR AXLE
Make sure that there is no marked “play” in the front or rear axles. Refer to FA X - 5 , "
WHEEL BEARING
INSPECTION" (Front), RAX-3, "WHEEL BEARING INSPECTION" (Rear).
OK or NG
OK >> GO TO 3.
NG >> Repair.
3. CHECK WHEEL SENSOR AND SENSOR ROTOR
Check wheel sensor and sensor rotor for the following.

Sensor installation for damage

Sensor rotor installation for damage

Sensor connector connection

Sensor harness inspection
OK or NG
OK >> GO TO 4.
NG >>

Replace sensor or sensor rotor.

Repair harness.
4. CHECK ABS WARNING LAMP DISPLAY
Make sure that the warning lamp turns off approximately 1 second after the ignition switch is turned ON or
when driving.
OK or NG
OK >> Normal
NG >> Perform self-diagnosis. Refer to BRC-58, "
Self-Diagnosis" .

Unexpected Pedal ReactionBFS000EL
1. CHECK BRAKE PEDAL STROKE
Check brake pedal stroke. Refer to BR-6, "
Inspection and Adjustment" .
Is the stroke too big?
YES >>
Bleed air from the brake piping. Refer to BR-10, "Bleeding Brake System" .

Check brake pedal, brake booster, and master cylinder mount for play, looseness, and brake
system fluid leakage, etc. Repair if necessary. Refer to Brake pedal: BR-7, "
COMPONENTS" ,
brake booster and master cylinder: BR-22, "
COMPONENTS" .
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.
OK or NG
OK >> GO TO 3. Check Wheel Sensor and Sensor Rotor. Refer to BRC-82, "Excessive ABS Function
Operation Frequently" .
NG >> Check brake system.
Longer Stopping DistanceBFS000EM
CAUTION:
The stopping distance on slippery road surfaces might be longer with the ABS operating than when
the ABS is not operating.
1. CHECK FUNCTION
Turn ignition switch OFF. Disconnect ABS actuator and electric unit (control unit) connector to deactivate ABS.
In this condition, check stopping distance. After inspection, connect connector.
OK or NG
OK >> GO TO 3. Check Wheel Sensor and Sensor Rotor. Refer to BRC-82, "Excessive ABS Function
Operation Frequently" .
NG >>

Bleed air from the brake piping. Refer to BR-10, "Bleeding Brake System" .

Check brake system.

TROUBLE DIAGNOSIS FOR SYMPTOMS

ABS Function Does Not OperateBFS000EN
CAUTION:
ABS does not operate when speed is 10 km/h (6 MPH) or lower.
1. CHECK ABS WARNING LAMP DISPLAY
Make sure that the warning lamp turns off approximately 2 second after the ignition switch is turned on or
when driving.
OK or NG
OK >> GO TO 3. Check Wheel Sensor and Sensor Rotor. Refer to BRC-82, "Excessive ABS Function
Operation Frequently" .
NG >> Perform self-diagnosis. Refer to BRC-58, "
Self-Diagnosis" .
Pedal Vibration and ABS Operation Sound OccursBFS000EO
CAUTION:
Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly
depressed (just place a foot on it). However, this is normal.

When shifting gears

When driving on slippery road

During cornering at high speed

When passing over bumps or grooves [at approximately 50 mm (1.97 in) or more]

When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or more]
1. SYMPTOM CHECK 1
Check if there is pedal vibration and operation sound when the engine is started.
OK or NG
OK >> GO TO 2.
NG >> Perform self-diagnosis. Refer to BRC-58, "
Self-Diagnosis" .
2. SYMPTOM CHECK 2
Check symptoms when electrical component (headlamps, etc.) switches are operated.
Do symptoms occur?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit. If there is,
move it farther away.
NO >> GO TO 3. Check Wheel Sensor and Sensor Rotor. Refer to BRC-82, "
Excessive ABS Function
Operation Frequently" .

Vehicle Jerks During VDC/TCS/ABS ControlBFS000EP
1. SYMPTOM CHECK
Check if the vehicle jerks during VDC/TCS/ABS control.
OK or NG
OK >> Normal
NG >> GO TO 2.
2. CHECK SELF-DIAGNOSTIC RESULTS
Perform self-diagnostic of ABS actuator and electric unit (control unit).
Are self-diagnostic results indicated?
YES >> Check the corresponding items, make repairs, and perform ABS actuator and electric unit (control
unit) self-diagnosis.
NO >> GO TO 3.
3. CHECK CONNECTOR
1. Turn ignition switch OFF, disconnect the ABS actuator and electric unit (control unit) connector and check
the terminal for deformation, disconnection, looseness, and so on. Repair or replace, if there is a malfunc-
tion.
2. Securely connect connectors. Perform ABS actuator and electric unit (control unit) self-diagnosis.
Are self-diagnostic results indicated?
YES >> If poor contact, damage, open or short circuit of connector terminal is found, repair or replace.
NO >> GO TO 4.
4. CHECK ECM AND TCM SELF-DIAGNOSTIC RESULTS
Perform ECM and TCM self-diagnosis.

ECM self-diagnosis: Refer to EC-394, "TROUBLE DIAGNOSIS" .

TCM self-diagnosis: Refer to AT- 3 4 , "TROUBLE DIAGNOSIS" or CVT-24, "TROUBLE DIAGNOSIS" .
Are self-diagnostic results indicated?
YES >> Check the corresponding items, make repairs.
NO >> Replace ABS actuator and electric unit (control unit).
