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.
How To Erase Self Diagnostic Result
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, 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, SLIP indicator 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 of brake fluid level switch operation (when brake fluid is insufficient).
VDC OFF switch should not stay in ON position.

DATA MONITOR
×: Applicable
–: Not applicable
ACTIVE TEST
The active test is used to determine and identify details of a malfunction, based on self-diagnosis test results and data obtained in the DATA MONITOR. In response to instructions from CONSULT, instead of those from ABS actuator and electric unit (control unit) on the vehicle, a drive signal is sent to the actuator to check its operation.
CAUTION:
Never perform ACTIVE TEST while driving the vehicle.
Always bleed air from brake system before active test.
Never perform active test when system is malfunctioning.
NOTE:
When active test is performed while depressing the pedal, the pedal depressing stroke may change. This is not a malfunction.
“TEST IS STOPPED” is displayed approx. 10 seconds after operation start.
When performing active test again after “TEST IS STOPPED” is displayed, select “BACK”.
ABS warning lamp, brake warning lamp and VDC warning lamp may turn ON during active test. This is not a malfunction.
ABS IN Valve and ABS OUT Valve
When “Up”, “Keep” or “Down” is selected on display screen, the following items are displayed when system is normal.
*: Immediately after being selected, status is “On”. Status changes to “Off” after approx. 2 seconds.
ABS IN Valve (ACT) and ABS OUT Valve (ACT)
When “Up”, “ACT UP” or “ACT KEEP” is selected on display screen, the following items are displayed when system is normal.
*: Immediately after being selected, status is “On”. Status changes to “Off” after approx. 10 seconds.
ABS Motor
When “On” or “Off” is selected on display screen, the following items are displayed when system is normal.
NOTE:
Display occasionally changes On/Off for a moment after ignition switch is turned ON. This is an operation for checking purposes and is not a malfunction.
