CONSULT Function (ABS)

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, 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.

  • Do not perform active test while driving vehicle.
  • Make sure to completely bleed air from brake system.
  • The active test cannot be performed with the ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp or brake warning lamp on.
  • ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp turn 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, touch BACK.

Test Item

ABS SOLENOID VALVE

  • Select "Up", "Keep" and "Down". Then use screen monitor to check that solenoid valve operates as shown in the table below.

ABS SOLENOID VALVE

*: 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 SOLENOID VALVE (ACT)

Select "Up", "ACT UP" and "ACT KEEP". Then use screen monitor to check that solenoid valve operates as shown in the table below.

ABS SOLENOID VALVE (ACT)

ABS SOLENOID VALVE (ACT)

*: 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.

ABS MOTOR

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.
