CONSULT Function (ABS)
FUNCTION
CONSULT can display each diagnostic item using the following diagnostic test modes.
|
Diagnostic test mode |
Function |
| ECU Identification | ABS actuator and electric unit (control unit) part number can be read |
| Self Diagnostic Result | Displays ABS actuator and electric unit (control unit) self-diagnosis results |
| Data Monitor | Displays ABS actuator and electric unit (control unit) input/output data in real time. |
| Active Test | Operation of electrical loads can be checked by sending drive signals to them |
| Work support | Supports inspections and adjustments. Commands are transmitted to the ABS actuator and electric unit (control unit) for setting the status suitable for required operation, input/output signals are received from the ABS actuator and electric unit (control unit) and received data is displayed. |
| CAN Diag Support Monitor | The result of transmit/receive diagnosis of CAN communication can be read. |
SELF DIAGNOSTIC RESULT MODE
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-Diagnosis Results
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 driving 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.

- Make sure to completely bleed air from brake system.
- The active test cannot be performed with the ABS warning lamp, VDC indicator lamp, SLIP indicator lamp or brake warning lamp 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. (Only solenoid valve and ABS motor)
- "TEST IS STOPPED" is displayed 10 seconds after operation start.
- After "TEST IS STOPPED" is displayed, to perform test again, touch BACK.
Test Item
SOLENOID VALVE
- When performing an active test of the ABS function, select "MAIN SIGNALS" for each test item.
- For ABS solenoid valve, touch "Up", "Keep", and "Down" on the display screen. For ABS solenoid valve (ACT), touch "Up", "ACT UP", "ACT KEEP" and confirm that solenoid valves operate as shown in the table below.
*: On for 1 to 2 seconds after the touch, and then Off
