FUNCTION
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
SELF DIAGNOSTIC RESULT
Operation Procedure
Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for approxi-
mately 1 minute.
Display Item List
Refer to BRC-48, "DTC No. Index".
How to Erase Self-diagnosis Results
After erasing DTC memory, start the engine and drive the vehicle at 30 km/h (19 MPH) or more for approxi-
mately 1 minute as the final inspection, and make sure that the ABS warning lamp and brake warning lamp
turn OFF.
CAUTION:
If memory cannot be erased, perform applicable diagnosis.
NOTE:
 When the wheel sensor malfunctions, after inspecting the wheel sensor system, ABS warning lamp and
brake warning lamp will not turn OFF even when the system is normal unless the vehicle is driven at approx-
imately 30 km/h (19 MPH) or more for approximately 1 minute.
 Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or in case of brake
fluid level switch operation (when brake fluid is insufficient).

Diagnostic test mode Function
Self diagnostic result Self-diagnostic results can be read and erased quickly.
Data monitor Input/Output data in the ABS actuator and electric unit (control unit) can be read.
Active testCONSULT-III drives some actuators apart from ABS actuator and electric unit (control unit) and
also shifts some parameters in a specified range.
ECU identification ABS actuator and electric unit (control unit) part number can be read.

SYMPTOM DIAGNOSIS
EXCESSIVE ABS FUNCTION OPERATION FREQUENCY
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
