CONSULT-II Inspection Procedure
SELF-DIAGNOSIS PROCEDURE
1) Turn ignition switch to OFF position.
2) Connect CONSULT-II to Data Link Con- nector.
1) Start engine.
2) Drive vehicle over 30 km/h (19 MPH) for at least one minute.
1) Stop vehicle with engine runningand touch ªSTARTº on CON-
SULT-II screen.
2) Touch ªABSº.
3) Touch ªSELF-DIAG RESULTSº.
I The screen shows the detected malfunc-
tion and how many times the ignition
switch has been turned since the mal-
function.
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 ªERASEº.
Check warning lamp(s) for deactivation
after driving vehicle over 30 km/h (19
MPH) for at least one minute.
Test the ABS system in a safe area to
verify that it functions properly.
END
Note: ªSELF-DIAG RESULTSº screen shows the detected malfunction and
how many times the ignition switch has been turned since the mal-
function.
