CONSULT-III Function (ABS)

INFOID:0000000000924811

FUNCTION

CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.

SELF-DIAG RESULTS MODE

Operation Procedure

1.

Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for
approximately 1 minute.

How to Erase Self-diagnosis Results

1.

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, ESP OFF indicator lamp,
SLIP indicator lamp and brake warning lamp turn OFF.

CAUTION:

If memory cannot be erased, perform applicably diagnosis.
NOTE:
• When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning lamp,

ESP OFF indicator lamp, SLIP indicator lamp and brake warning lamp will not turn OFF even when the
system is normal unless the vehicle is driving at approximately 30 km/h (19 MPH) or more for approxi-
mately 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).

• ESP OFF switch should not stay “ON” position.

Diagnostic test mode

Function

Work support

This mode enables a technician to adjust some devices faster and more accurately by following 
the indications on CONSULT-III.

Self-diagnostic results

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 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.

ECU part number

ABS actuator and electric unit (control unit) part number can be read.

CAN diagnostic support monitor

The results of transmit/receive diagnosis of CAN communication can be read.
