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.

TROUBLE DIAGNOSES

pA
Check warning lamp for deactivation after
driving vehicle over 30 km/h (19 mph) for
at least one minute.
After making certain that warning lamp
does not come on, test the ABS in a safe
area to verify that it functions properly.
HOW TO READ SELF-DIAGNOSTIC RESULTS (Malfunction codes)
lîîîDetermine the code No. by counting the number of times the warning lamp flashes on and off.
lWhen several malfunctions occur at one time, up to three code numbers can be stored; the latest mal-
function will be indicated first.
lThe indication begins with the start code 12. After that a maximum of three code numbers appear in
the order of the latest one first. The indication then returns to the start code 12 to repeat (the indica-
tion will stay on for five minutes at the most).
lThe malfunction code chart is given on the next page.
HOW TO ERASE SELF-DIAGNOSTIC RESULTS
(Malfunction codes)
1. Disconnect the check terminal from ground (ABS warning
lamp will stay lit).
2. Within 12.5 seconds, ground the check terminal 3 times.
Each terminal ground must last more than 1 second. The
ABS warning lamp goes out after the erase operation has
been completed.
3. Perform self-diagnosis again. Refer to BR-67. Only the start-
code should appear, no malfunction codes.
