Self-diagnosis (Only models with data link
connector terminal No. 8)
FUNCTION
lWhen a problem occurs in the ABS, the warning lamp on the
instrument panel comes on. To start the self-diagnostic
results mode, ground the self-diagnostic (check) terminal
located on ªData Link Connector for CONSULT-IIº. The loca-
tion of the malfunction is indicated by the warning lamp flash-
ing.
SELF-DIAGNOSIS PROCEDURE
Drive vehicle over 30 km/h (19 mph) for at
least one minute.
Turn ignition switch to the ªLOCKº position.
Ground terminal ª8º of ªDATA LINK CON-
NECTOR for CONSULT-IIº with a suitable
harness.
Turn ignition switch to ªONº position while
grounding terminal ª8º.
Do not depress brake pedal.
After 3.0 seconds, the warning lamp starts
flashing to indicate the malfunction code
No. (See NOTE.)
Verify the location of the malfunction with
the malfunction code chart. Refer to BR-69.
Then make the necessary repairs following
the diagnostic procedures.
After the malfunctions are repaired, erase
the malfunction codes stored in the control
unit. Refer to BR-68.
Rerun the self-diagnostic results mode to
verify that the malfunction codes have been
erased.
NOTE: The indication ter-
minates after five
minutes.
However, when the
ignition switch is
turned from off to
on, the indication
starts flashing
again. Disconnect the check terminal from the
ground. The self-diagnostic results mode is
now complete.

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.
