CONSULT-III Function
INFOID:0000000001635039
FUNCTION
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
SELF-DIAG RESULTS MODE
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.
How to Erase Self-diagnosis Results
After erasing DTC memory, start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1
minute as the final inspection, and make sure that the ABS warning lamp, VDC OFF indicator lamp, SLIP indi-
cator 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, the ABS warning lamp,
VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp will not turn OFF even when the sys-
tem is normal unless the vehicle is driving at approximately 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 of brake fluid
level switch operation (when brake fluid is insufficient).
• VDC OFF switch should not stay “ON” position.

Data monitor
Input/Output data in the ABS actuator and electric unit (control unit) can be read.
Active test
Diagnostic test mode is which CONSULT-III drives some actuators apart from the ABS actuator
and electric unit (control unit) and also shifts some parameters in a specified range.

ACTIVE TEST MODE
CAUTION:
• Do not perform active test while driving vehicle.
• Make sure to completely bleed air from brake system.
• The active test cannot be performed with the ABS warning lamp, VDC OFF indicator lamp, SLIP indi-
cator lamp and brake warning lamp are on.
• ABS warning lamp, VDC OFF indicator lamp, SLIP indicator 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.
Test Item
ABS SOLENOID VALVE
• Touch “Up”, “Keep” and “Down”. Then use screen monitor to check that solenoid valve operates as shown in
the table below.
