• If ABS actuator and electric unit (control unit) connection is loose, tighten the piping to the specified
torque and recheck for leaks.
• If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) threads,
replace the damaged part and recheck for leaks.
• When there is fluid leaking or seeping from a fluid connection, use a clean cloth to wipe off the fluid and
recheck for leaks. If fluid is still seeping out, replace the damaged part. If the fluid is leaking at the ABS
actuator and electric unit (control unit), replace the ABS actuator and electric unit (control unit) assem-
bly.
CAUTION:
The ABS actuator and electric unit (control unit) cannot be disassembled and must be replaced
as an assembly.
3. Check the brake pads for excessive wear.
POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure the battery positive cable, negative cable and ground connection are not loose. In addition, make
sure the battery is sufficiently charged.
ABS WARNING LAMP INSPECTION
1. Make sure ABS warning lamp turns on for approximately 2 seconds when the ignition switch is turned ON.
If it does not, check CAN communications. If there are no errors with the CAN communication system,
replace the combination meter. Refer to IP-11, "
Removal and Installation".
2. Make sure the lamp turns off approximately 2 seconds after the ignition switch is turned ON. If the lamp
does not turn off, conduct self-diagnosis of ABS actuator and electric unit (control unit). If no malfunctions
are detected in self-diagnosis, replace combination meter. Refer to IP-11, "
Removal and Installation".
3. After conducting the self-diagnosis, be sure to erase the error memory. Refer to BRC-18, "
CONSULT-III
Function (ABS)".

SELF-DIAGNOSIS
Description
If an error is detected in the system, the ABS warning lamp will turn on. In this case, perform self-diagnosis as
follows:
Operation Procedure
1. Turn ignition switch OFF.
2. Connect CONSULT-III to the data link connector.
3. Turn ignition switch ON.
4. Start engine and drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
5. After stopping the vehicle, with the engine running, touch “ABS”, “SELF-DIAG RESULTS” in order on the
CONSULT-III screen.
6. The self-diagnostic results are displayed. (If necessary, the self-diagnostic results can be printed out by
touching “PRINT”.)
• When “NO DTC IS DETECTED” is displayed, check the ABS warning lamp.
7. Conduct the appropriate inspection from the display item list, and repair or replace the malfunctioning
component.
8. Start engine and drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
CAUTION:
• When a wheel sensor “short-circuit” is detected, if the vehicle is not driven at 30 km/h (19 MPH)
for at least 1 minute, the ABS warning lamp will not turn off even if the malfunction is repaired.
9. Turn ignition switch OFF to prepare for erasing the memory.
10. Start the engine and touch “ABS”, “SELF-DIAG RESULTS”, “ERASE” in order on the CONSULT-III screen
to erase the error memory.
If “ABS” is not indicated, go to GI-36, "
CONSULT-III Data Link Connector (DLC) Circuit".
CAUTION:
If the error memory is not erased, re-conduct the operation from step 5.
11. For the final inspection, drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute and
confirm that the ABS warning lamp is off.

INSPECTION PROCEDURE
1.CONNECTOR INSPECTION
Disconnect the ABS actuator and electric unit (control unit) connector E33 and wheel sensor of malfunctioning
code.
Check the terminals for deformation, disconnection, looseness or damage.
OK or NG
OK >> GO TO 2.
NG >> Repair or replace as necessary.
2.CHECK WHEEL SENSOR OUTPUT SIGNAL
1. Connect ABS active wheel sensor tester (J-45741) to wheel sensor using appropriate adapter.
2. Turn on the ABS active wheel sensor tester power switch.
NOTE:
The green POWER indicator should illuminate. If the POWER indicator does not illuminate, replace the
battery in the ABS active wheel sensor tester before proceeding.
3. Spin the wheel of the vehicle by hand and observe the red SENSOR indicator on the ABS active wheel
sensor tester. The red SENSOR indicator should flash on and off to indicate an output signal.
NOTE:
If the red SENSOR indicator illuminates but does not flash, reverse the polarity of the tester leads and
retest.
Does the ABS active wheel sensor tester detect a signal?
YES >> GO TO 3.
NO >> Replace the wheel sensor. Refer to BRC-32, "
Removal and Installation".
3.CHECK TIRES
Check for inflation pressure, wear and size of each tire. Refer to WT-25
.
Are tire pressure and size correct and is tire wear within specifications?
YES >> GO TO 4.
NO >> Adjust tire pressure or replace tire(s).
4.CHECK WHEEL BEARINGS
Check wheel bearing axial end play. Refer to FAX-5, "
On-Vehicle Inspection and Service" or RAX-4, "On-Vehi-
cle Inspection and Service".
OK or NG
OK >> GO TO 5.
NG >> Repair or replace as necessary. Refer to FA X - 5 , "
Removal and Installation" or RAX-4, "Removal
and Installation".
5.CHECK WIRING HARNESS FOR SHORT CIRCUIT
1. Disconnect ABS actuator and electric unit (control unit) connec-
tor and wheel sensor connector of malfunction code No.
2. Check continuity between wheel sensor harness connector ter-
minals and ground.
OK or NG
OK >> GO TO 6.
NG >> Repair the circuit.
6.CHECK WIRING HARNESS FOR OPEN CIRCUITContinuity should not exist.

CAN Communication System InspectionINFOID:0000000001703844
INSPECTION PROCEDURE
1.CHECK CONNECTOR
1. Turn ignition switch OFF, disconnect the ABS actuator and electric unit (control unit) connector and check
the terminals for deformation, disconnection, looseness, and so on. If there is a malfunction, repair or
replace the terminal.
2. Reconnect connector to perform self-diagnosis.
Is "CAN COMM CIRCUIT" displayed in self-diagnosis display items?
YES >> Print out the self-diagnostic results, and refer to LAN-15, "Trouble Diagnosis Flow Chart".
NO >> Connector terminal is loose, damaged, open, or shorted.Ground1

TROUBLE DIAGNOSES FOR SYMPTOMS
2. Drive vehicle and check brake operation.
NOTE:
• Stopping distance may be longer than vehicles without ABS when road condition is slippery.
• Driving the vehicle with the ABS actuator and electric unit (control unit) disconnected may induce DTCs
in electrical control units using CAN communication. After the inspection, clear all DTCs. Refer to LAN-
6, "System Description".
OK or NG
OK >> GO TO 4.
NG >> Perform Basic Inspection. Refer to BRC-16, "
Basic Inspection".
4.CHECK WHEEL SENSORS
Check the following.
• Wheel sensor mounting for looseness
• Wheel sensors for physical damage
• Wheel sensor connectors for terminal damage or loose connections
• Sensor rotor and mount for physical damage
OK or NG
OK >> Check ABS actuator and electric unit (control unit) connector terminals for deformation, discon-
nection, looseness or damage. Reconnect ABS actuator and electric unit (control unit) harness
connector. Then retest.
NG >> Repair or replace as necessary.
Long Stopping DistanceINFOID:0000000001703847
1.CHECK BASE BRAKING SYSTEM PERFORMANCE
1. Disable ABS by disconnecting ABS actuator and electric unit (control unit) connector.
2. Drive vehicle and check brake operation.
NOTE:
• Stopping distance may be longer than vehicles without ABS when road condition is slippery.
• Driving the vehicle with the ABS actuator and electric unit (control unit) disconnected may induce DTCs
in electrical control units using CAN communication. After the inspection, clear all DTCs. Refer to LAN-
6, "System Description".
OK or NG
OK >> Go to BRC-29, "ABS Works Frequently".
NG >> Perform Basic Inspection. Refer to BRC-16, "
Basic Inspection".
ABS Does Not WorkINFOID:0000000001703848
CAUTION:
The ABS does not operate when the vehicle speed is 10 km/h (6 MPH) or less.
1.CHECK WARNING LAMP ACTIVATION
Turn ignition switch ON and check for warning lamp activation.
• Warning lamp should activate for approximately 2 seconds after turning the ignition switch ON.
OK or NG
OK >> Carry out self-diagnosis. Refer to BRC-18, "CONSULT-III Function (ABS)".
NG >> Go to BRC-16, "
Basic Inspection".
Pedal Vibration or ABS Operation NoiseINFOID:0000000001703849
NOTE:
During ABS activation, pedal vibration may be felt and a noise may be heard. This is normal and does not indi-
cate a malfunction.
1.CHECK SYMPTOM
1. Apply brake.
2. Start engine.
Does the symptom occur only when engine is started?
YES >> Carry out self-diagnosis. Refer to BRC-18, "CONSULT-III Function (ABS)".
