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).

NOTE:
1: A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is an
operation for checking.
ACTIVE TEST
CAUTION:
• Do not perform active test while driving vehicle.
 Make sure to completely bleed air from brake system.
 The active test cannot be started when ABS warning lamp and brake warning lamp are ON.
 ABS warning lamp and brake warning lamp are ON during active test.
NOTE:
 When active test is performed while depressing the pedal, the pedal depression amount will change. This is
normal. (Only solenoid valve and ABS motor.)
 “TEST IS STOPPED” is displayed 10 seconds after operation start.
 After “TEST IS STOPPED” is displayed, to perform test again.
