CONSULT Function (ABS)
INFOID:0000000009365065
APPLICATION ITEMS
CONSULT can display each diagnostic item using the following direct diagnostic modes.
ECU IDENTIFICATION
ABS actuator and electric unit (control unit) part number is displayed.
SELF DIAGNOSTIC RESULT
Operation Procedure
1. 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
1. 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 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
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).

ABS SOLENOID VALVE
• Select “Up”, “Keep” and “Down”. Then use screen monitor to check that solenoid valve operates as shown in
the table below.
*: On for 1 to 2 seconds after the select, and then Off.
NOTE:
A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is an
operation for checking.
ABS MOTOR
• Select “On” and “Off”. Make sure motor relay and actuator relay operates as shown in table below.
NOTE:
A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is an
operation for checking.
