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, ABS warning lamp, VDC
warning lamp and brake warning lamp will not turn OFF even when the system is normal unless the vehicle
is driven 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 in case of brake
fluid level switch operation (when brake fluid is insufficient).
• VDC OFF switch should not stay “ON” position.
DATA MONITOR MODE
Display Item List
NOTE:
The following table includes information (items) inapplicable to this vehicle. For information (items) applicable
to this vehicle, refer to CONSULT display items.
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.
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 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.

NOTE:
A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not mal-
function because it is an operation for checking.
ACTIVE TEST MODE
CAUTION:
• Never 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, VDC warning lamp and brake warning
lamp are ON.
• ABS warning lamp, VDC warning lamp and brake warning lamp are ON during active test.
