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 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 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.

SELF DIAGNOSTIC RESULT
Operation Procedure
Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
Display Item List
Refer to
DTC No. Index
.
How to Erase Self-diagnosis Results
After erasing DTC memory, start the engine and drive the vehicle at 30 km/h (19 MPH) or more for approximately 1 minute as the final inspection, and check 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, ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp, and brake warning lamp do 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 turns ON when parking brake operation (when switch is ON) or when brake fluid level switch operation (when brake fluid is insufficient).
Set-up switch (VDC) should not stay in the “OFF mode” position.

ACTIVE TEST
■ CAUTION ■
Never perform active test while driving vehicle.
Always completely bleed air from brake system.
The active test cannot be started when ABS warning lamp, VDC OFF indicator lamp, SLIP indicator 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.
“TEST IS STOPPED” is displayed 10 seconds after operation start.
After “TEST IS STOPPED” is displayed, to perform test again.
