instrument panel NISSAN PICK-UP 1998 Repair Manual

Self-diagnosis
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 ``Data Link Connector for CONSULT''. 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 ``OFF''.
Ground terminal ``4'' of ``Data link con-
nector for CONSULT'' with a suitable
harness.
Turn ignition switch ``ON'' while ground-
ing terminal ``4''.
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-55. Then make the necessary
repairs following the diagnostic proce-
dures.
After the malfunctions are repaired,
erase the malfunction codes stored in
the control unit. Refer to BR-54.
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
``OFF'' to ``ON'', the indica-
tion starts flashing again.

Service Notice
lWhen removing or installing various parts, place a cloth or padding onto the vehicle body to prevent
scratches.
lHandle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to soil
or damage them.
lApply sealing compound where necessary when installing parts.
lWhen applying sealing compound, be careful that the sealing compound does not protrude from parts.
lWhen replacing any metal parts (for example body outer panel, members, etc.), be sure to take rust
prevention measures.
Supplemental Restraint System (SRS) ``AIR
BAG'' (4WD models)
The Supplemental Restraint System ``AIR BAG'', used along with a seat belt, helps to reduce the risk or
severity of injury to the driver in a frontal collision. The Supplemental Restraint System consists of air bag
module (located in the center of the steering wheel), a diagnosis sensor unit, warning lamp, wiring harness
and spiral cable. Information necessary to service the system safely is included in theRS sectionof this
Service Manual.
WARNING:
lTo avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses are covered with yellow insulation either just before the
harness connectors or for the complete harness, for easy identification.

Introduction
The ECM (ECCS control module) has an on board diagnostic system, which detects malfunctions related to
engine sensors or actuators. Self-diagnosis items are listed in ``DIAGNOSTIC TROUBLE CODE INDEX'',
EC-1.
The malfunction indicator lamp (MIL) on the instrument panel lights up when a malfunction is detected, or
when the ECM enters fail-safe mode (Refer to EC-61).
Diagnostic Trouble Code (DTC)
HOW TO CONFIRM MALFUNCTION ITEMS
Malfunction items can be confirmed by the following methods.
1. The number of blinks of the malfunction indicator lamp in the Diagnostic Test Mode II (Self- Diag-
nostic Results) indicates the DTC. Examples: 11, 21 etc.
2. CONSULT displays the malfunctioning component or system in ``SELF DIAGNOSTIC RESULTS''
mode.
lOutput of a DTC indicates a malfunction. However, Mode II does not indicate whether the mal-
function is still occurring or has occurred in the past and has returned to normal.
CONSULT can identify malfunction status as shown below. Therefore, using CONSULT (if avail-
able) is recommended.
A sample of CONSULT display is shown at left. The malfunction
is displayed in SELF-DIAGNOSTIC RESULTS mode of CON-
SULT. Time data indicates how many times the vehicle was
driven after the last detection of a malfunction.
If the malfunction is being detected currently, the time data will
be ``0''.
HOW TO ERASE DTC
The DTC can be erased from the back-up memory in the ECM by the following methods.
Selecting ``ERASE'' in the SELF- DIAG RESULTS'' mode with CONSULT
Changing the diagnostic test mode from Diagnostic Test Mode II to Mode I by turning the mode
selector on the ECM (RHD model only) or connecting the data link connector for CONSULT terminals.
(Refer to EC-39, 41)
lIf the battery terminal is disconnected, the DTC will be lost within 24 hours.
lErasing the DTC, using CONSULT is easier and quicker than switching the mode selector on the
ECM (RHD model only) or connecting the data link connector for CONSULT terminals.

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTIONKA
EC-36

Malfunction Indicator Lamp (MIL)
The malfunction indicator lamp is located on the instrument
panel.
1. The malfunction indicator lamp will light up when the ignition
switch is turned ON without the engine running. This is for
checking the blown lamp.
lIf the malfunction indicator lamp does not light up, see the
WARNING LAMPS AND CHIME in the EL section.
(Or see EC-173, 174.)
2. When the engine is started, the malfunction indicator lamp
should go off.
If the lamp remains on, the on board diagnostic system has
detected an engine system malfunction.
ON BOARD DIAGNOSTIC SYSTEM FUNCTION
The on board diagnostic system has the following four functions.
Diagnostic Test Mode I
1. BULB CHECK : This function checks the bulb for damage (blown, open circuit, etc.) of
the malfunction indicator lamp.
If the MIL does not come on, check MIL circuit and ECM test mode
selector. (See next page.)
2. MALFUNCTION
WARNING: This is a usual driving condition. When a malfunction is detected, the
MIL will light up to inform the driver that a malfunction has been
detected.
Diagnostic Test Mode II
3. SELF-DIAGNOSTIC
RESULTS: This function allows DTCs to be read.
4. HEATED OXYGEN
SENSOR MONITOR: This function allows the fuel mixture condition (lean or rich), monitored
by heated oxygen sensor, to be read.
MIL Flashing without DTC
If the ECM is in Diagnostic Test Mode II, the MIL may flash when the engine is running. In this case, check
ECM test mode selector following ``HOW TO SWITCH DIAGNOSTIC TEST MODES'' on next page.
How to switch the diagnostic test (function) modes and details of the above functions are described later.
(See page EC-39, 41.)
