CONSULT Function
INFOID:0000000007544640
FUNCTION
CONSULT 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, start the engine and drive the vehicle at 30 km/
h (19 MPH) or more for approximately 1 minute.
Display Item List
How to Erase Self-diagnosis Results
After erasing DTC memory for “ABS” with CONSULT, 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 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, the ABS warning lamp,
VDC warning 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 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.
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 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.
