CONSULT-II Inspection Procedure
SELF-DIAGNOSIS PROCEDURE
1) Turn ignition switch to the ªLOCKº
position.
2) Connect CONSULT-II to Data Link
Connector.
1) Start engine.
2) Drive vehicle over 30 km/h (19 mph)
for at least one minute.
1) Stop vehicle with engine run-
ning and touch ªSTARTº on
CONSULT-II screen.
2) Touch ªABSº.
3) Touch ªSELF-DIAG RESULTSº.
lThe screen shows the detected
malfunction and how many times
the ignition switch has been
turned since the malfunction.
MALFUNCTION REPAIR
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Make the necessary repairs following
the diagnostic procedures.
After repairing the malfunctions, erase
the self-diagnostic results stored in the
control unit by touching ªERASEº.
Check warning lamp for deactivation
after driving vehicle over 30 km/h (19
mph) for at least one minute.
End
Note: ªSELF-DIAG RESULTSº screen shows the detected malfunction
and the times of ignition switch on and off after it occurred.

H: If one or more wheels spin on a rough or slippery road for 40 seconds or more, the ABS warning lamp will illuminate. This does
not indicate a malfunction. Only in the case of the short-circuit after repair the ABS warning lamp also illuminates when the igni-
tion switch is turned ªONº. In this case, drive the vehicle at speeds greater than 30 km/h (19 MPH) for approximately 1 minute
as specified in ªSELF-DIAGNOSIS PROCEDUREº, BR-70. Check to ensure that the ABS warning lamp goes out while the
vehicle is being driven.

*: Under voltage that is too low, the control unit disable the ABS. It does not set the ABS in fail-safe condition. Instead, the ABS
becomes a conventional brake system. After the power supply has resumed, the warning lamp goes off, making it possible for the
ABS to be re-engaged.
