CONSULT-III Function

INFOID:0000000005517270

FUNCTION

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

WORK SUPPORT

SELF DIAGNOSTIC RESULT

Operation Procedure

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

Display Item List

Refer to 

BRC-96, "DTC No. Index"

.

How to Erase Self-diagnosis Results

After erasing DTC memory for “ABS” with CONSULT-III, start the engine and drive the 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 indicator 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

Display Item List

Diagnostic test mode

Function

Work support

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

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 test

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 identification

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

Item

Description

ST ANGLE SENSOR ADJUSTMENT

Adjusts the neutral position of the steering angle sensor.

DECEL G SEN CALIBRATION

Calibrates decel G sensor.
