CONSULT-III can display each diagnostic item us
ing the diagnostic test modes shown following.
SELF-DIAGNOSIS
Description
If an error is detected in the system, the ABS warning lamp will turn on. In this case, perform self-diagnosis as
follows:
Operation Procedure
1. Turn ignition switch OFF.
2. Connect CONSULT-III To the data link connector.
3. Turn ignition switch ON.
4. Start engine and drive at approximately 30 km/h (19 MPH) for approximately 1 minute.
5. After stopping the vehicle, with the engine running, t ouch “ABS”, “SELF-DIAG RESULTS” in order on the
CONSULT-III screen.

ABS diagnostic mo de Description
WORK SUPPORT Supports inspection and adjustment
s. 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.
SELF DIAGNOSTIC RESULT Displays ABS ac tuator and electric unit (control unit) self-diagnosis results.
DATA MONITOR Displays ABS actuator and electric unit (control unit) input/output data in real time.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read. ACTIVE TEST Operation of electrical loads can be checked by sending drive signal to them.
FUNCTION TEST Conducted by CONS ULT-III instead of a technician to determine whether each system is "OK" or "NG".
ECU IDENTIFICATION ABS actuator and electric unit (control unit) part number can be read.

6. The self-diagnostic results are displayed. • When “NO DTC IS DETECTED” is displayed, check the ABS warning lamp, SLIP indicator lamp and
VDC OFF indicator lamp.
7. Conduct the appropriate inspection from the display item list, and repair or replace the malfunctioning
component.
8. Start engine and drive at approximately 30 km /h (19 MPH) for approximately 1 minute.
CAUTION:
• When a wheel sensor “short-circuit” is detected, if the vehicle is not driven at 30 km/h (19 MPH)
for at least 1 minute, the ABS warn ing lamp will not turn off even if the malfunction is repaired.
9. Turn ignition switch OFF to prepare for erasing the memory.
10. Start the engine and touch “ABS”, “SELF-DIAG RESULTS”, “ERASE” in order on the CONSULT-III screen to erase the error memory.
If “ABS” is not indicated, go to GI-36, "
CONSULT-III Data Link Connector (DLC) Circuit".
CAUTION:
If the error memory is not erased, re -conduct the operation from step 5.
11. For the final inspection, drive at approximately 30 km/h (19 MPH) for approximately 1 minute and confirm
that the ABS warning lamp, SLIP indicator lamp, and VDC OFF indicator lamp are off.
