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).

REMOVAL
Be careful of the following.
CAUTION:
When removing the wheel sensor, do not rotate it if possible, and do not forcibly pull the wheel sensor
harness.
INSTALLATION
Note the following, and tighten bolts to the specified torque.
Check the inside of the wheel sensor mounting hole for foreign materials, the rotor surface for iron chips
and other foreign materials. Clean both the wheel sensor mounting hole and the rotor surface before
installation. Replace the wheel sensor if there is any non-standard condition.
Completely push in rubber clamp of strut bracket and body bracket until they lock when installing front
wheel sensor so that the wheel sensor harness will not be twisted. Install grommet groove onto bracket
with yellow line on the harness facing bracket opening (mounting hole). There should be no twists in the
harness when installed.
When installing the rear sensor, securely install the harness mount of the rear suspension member so that
the wheel sensor harness is not twisted. In addition, there should be no twists in the harness when
installed.

REMOVAL
1. Disconnect ABS actuator and electric unit (control unit) connector.
2. Loosen brake tube flare nuts, then remove brake tubes from ABS actuator and electric unit (control unit).
3. Remove ABS actuator and electric unit (control unit) mounting nuts.
4. Remove ABS actuator and electric unit (control unit) from vehicle.
CAUTION:
Be careful of the following when removing ABS actuator and electric unit (control unit).
If the part number on the part number label (pasted on actuator upper surface) is the same, ABS
actuator and electric unit (control unit) cannot be used on another vehicle.
If it is used on another vehicle, ABS warning lamp, SLIP indicator lamp and VDC OFF indicator
lamp may turn ON or VDC/TCS/ABS may not operate normally.
When replacing ABS actuator and electric unit (control unit), must use new service parts.
Before servicing, disconnect battery cables.
To remove brake tube, use a flare nut torque wrench to prevent flare nuts and brake tube from
being damaged. To install, use a flare nut torque wrench (commercial service tool) and tighten
with the specified torque.
Do not apply excessive impact to actuator, such as dropping it.
Do not remove and install ABS actuator and electric unit (control unit) by holding harness.
INSTALLATION
Install is in the reverse order of the removal.
CAUTION:
Be careful of the following when installing ABS actuator and electric unit (control unit).
Tighten the mounting bolts and nuts with the specified torque.
After the work, bleed air from brake piping. Refer to BR-10, "Bleeding Brake System" .
After installing body harness connector in the actuator, make sure connector is securely locked
When replacing ABS actuator and electric unit (control unit), calibrate Steering angle sensor neu-
tral position. Refer to BRC-40, "
Adjustment of Steering Angle Sensor Neutral Position" .
