Self-diagnosis
FUNCTION
+When 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 Connectorº. The location of the mal-
function is indicated by the warning lamp flashing.
+While DIFF-LOCK is on, anti-lock warning light flashes.
SELF-DIAGNOSIS PROCEDURE
Turn off DIFF-LOCK switch.
Drive vehicle over 30 km/h (19 MPH) for
at least one minute.
Turn ignition switch ªOFFº.
Ground terminal ª9º of ªData link connec-
torº with a suitable harness.
Turn ignition switch ªONº while ground-
ing terminal ª9º.
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
the original Service Manual. Then make
the necessary repairs following the diag-
nostic procedures.
After the malfunctions are repaired,
erase the malfunction codes stored in
the control unit. Refer to the original Ser-
vice Manual.
Rerun the self-diagnostic results mode to
verify that the malfunction codes have
been erased.
Disconnect the check terminal from the
ground. The self-diagnostic results mode
is now complete.NOTE: The indication terminates
after five minutes.
However, when the ignition
switch is turned from
ªOFFº to ªONº, the indica-
tion starts flashing again.
