CONSULT Inspection Procedure
SELF-DIAGNOSIS PROCEDURE
1) Turn ignition switch OFF.
2) Connect CONSULT to Data Link Con-
nector for CONSULT.
1) Start engine.
2) Drive vehicle over 30 km/h (19 MPH)
for at least one minute.
1) Stop vehicle with engine running
and touch ``START'' on CONSULT
screen.
2) Touch ``ABS''.
3) Touch ``SELF-DIAG RESULTS''.
lThe screen shows the detected mal-
function and how many times the igni-
tion switch has been turned since the
malfunction.
Make the necessary repairs following the
diagnostic procedures.
After the malfunctions are repaired, erase
the self-diagnostic results stored in the
control unit by touching ``ERASE''.
Check warning lamp for deactivation after
driving vehicle over 30 km/h (19 MPH) for
at least one minute.
Test the ABS in a safe area to verify that
it functions properly.
Note: ``SELF-DIAG RESULTS'' screen shows the detected malfunction and
how many times the ignition switch has been turned since the mal-
function.

.1: 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 (Code Nos. 26, 22, 32 and 36), after repair the ABS warn-
ing lamp also illuminates when the ignition switch is turned ``ON''. In this case, drive the vehicle at speeds greater than 30 km/h
(19 MPH) for approximately 1 minute as specified in ``SELF-DIAGNOSIS PROCEDURE'', BR-53. Check to ensure that the ABS
warning lamp goes out while the vehicle is being driven.
