Self-diagnosis (Only Models with Data Link
Connector Terminal No. 9)
NJBR0091FUNCTIONNJBR0091S01+When a problem occurs in the ABS, the ABS 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 malfunc-
tion is indicated by the ABS warning lamp flashing.
SELF-DIAGNOSIS PROCEDURENJBR0091S021. Drive vehicle over 30 km/h (19 MPH) for at least one minute.
2. Turn ignition switch ªOFFº.
SEF378Y
3. Ground terminal ª9º of ªData link connectorº with a suitable
harness.
4. Turn ignition switch ªONº while grounding terminal ª9º.
Do not depress brake pedal.
Do not start engine.
SBR759E
5. After 3.0 seconds, the ABS warning lamp starts flashing to
indicate the malfunction code No. (See NOTE.)
6. Verify the location of the malfunction with the malfunction code
chart. Refer to BR-76. Then make the necessary repairs fol-
lowing the diagnostic procedures.
7. After the malfunctions are repaired, erase the malfunction
codes stored in the control unit. Refer to BR-64.
8. Rerun the self-diagnostic results mode to verify that the mal-
function codes have been erased.
SEF378Y
9. Disconnect the check terminal from the ground. The self-diag-
nostic results mode is now complete.
10. Check ABS warning lamp for deactivation after driving vehicle
over 30 km/h (19 MPH) for at least one minute.
11. After making certain that ABS warning lamp does not come on,
test the ABS SELF-DIAGNOSIS in a safe area to verify that it
functions properly.
NOTE:
The indication terminates after five minutes.
However, when the ignition switch is turned from ªOFFº to ªONº, the
indication starts flashing again.

HOW TO READ SELF-DIAGNOSTIC RESULTS
(MALFUNCTION CODES)
NJBR0091S031. Determine the code No. by counting the number of times the
ABS warning lamp flashes on and off.
2. When several malfunctions occur at one time, up to three code
numbers can be stored; the latest malfunction will be indicated
first.
3. The indication begins with the start code 12. After that a maxi-
mum 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 indication will stay on for five minutes at the most).
4. The malfunction code chart is given on the BR-76 page.
SBR457D
ABR256
HOW TO ERASE SELF-DIAGNOSTIC RESULTS
(MALFUNCTION CODES)
NJBR0091S041. 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 warn-
ing lamp goes out after the erase operation has been com-
pleted.
3. Perform self-diagnosis again. Refer to BR-63. Only the start
code should appear, no malfunction codes.

+Do not perform fuel pressure check with system operat-
ing. Fuel pressure gauge may indicate false readings.
1. Release fuel pressure to zero.
2. Disconnect fuel hose between fuel filter and fuel tube (engine
side).
3. Install pressure gauge between fuel filter and fuel tube.
4. Start engine and check for fuel leakage.
5. Read the indication of fuel pressure gauge.
