warning NISSAN PICK-UP 2001 User Guide

Diagnostic test mode I Ð Bulb check
In this mode, the MIL on the instrument panel should stay ON. If it remains OFF, check the bulb. Refer to
EL section, ªWARNING LAMPS AND CHIMEº or see EC-3647.
Diagnostic test mode I Ð Malfunction warning
MIL Condition
ON When the malfunction is detected or the ECM's CPU is malfunctioning.
OFF No malfunction.
Diagnostic test mode II Ð Self-diagnostic results
In this mode, DTC is indicated by the number of blinks of the MIL as shown below.
Long (0.6 second) blinking indicates the two LH digits of number and short (0.3 second) blinking indicates
the two RH digits of number. For example, the MIL blinks 10 times for 6 seconds (0.6 sec x 10 times) and
then it blinks three times for about 1 second (0.3 sec x 3 times). This indicates the DTC ª1003º.
In this way, all the detected malfunctions are classified by their DTC numbers. The DTC ª0505º refers to no
malfunction. (See TROUBLE DIAGNOSIS Ð INDEX, EC-3400.)
How to erase diagnostic test mode II (Self-diagnostic results)
The DTC can be erased from the backup memory in the ECM when the diagnostic test mode is changed
from Diagnostic Test Mode II to Diagnostic Test Mode I. (Refer to ªHow to Switch Diagnostic Test Modesº,
EC-3431.)
+If the battery terminal is disconnected, the DTC will be lost from the backup memory within 24
hours.
+Be careful not to erase the stored memory before starting trouble diagnoses.

Overall Function Check
Use this procedure to check the overall function of the cooling
fan. During this check, a DTC might not be confirmed.
WARNING:
Never remove the radiator cap when the engine is hot. Seri-
ous burns could be caused by high pressure fluid escaping
from the radiator.
Wrap a thick cloth around the cap. Carefully remove the cap
by turning it a quarter turn to allow built-up pressure to
escape. Then turn the cap all the way off.
WITH CONSULT-II
1) Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is
below the proper range, skip the following steps and go to
ªDiagnostic Procedureº, EC-3494.
2) Confirm whether customer filled the coolant or not. If cus-
tomer filled the coolant, skip the following steps and go to
ªDiagnostic Procedureº, EC-3494.
3) Turn ignition switch ªONº.
4) Perform ªCOOLING FANº in ªACTIVE TESTº mode with
CONSULT-II and make sure that cooling fans operate when
touching ªONº or ªOFFº.
If NG, go to ªDiagnostic Procedureº, EC-3494.
WITHOUT CONSULT-II
1) Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is
below the proper range, skip the following steps and go to
ªDiagnostic Procedureº, EC-3494.
2) Confirm whether customer filled the coolant or not. If cus-
tomer filled the coolant, skip the following steps and go to
ªDiagnostic Procedureº, EC-3494.
3) Disconnect engine coolant temperature sensor harness con-
nector.
4) Connect 150Wresistor to engine coolant temperature sensor
harness connector.
5) Start engine and make sure that cooling fan operates.
Be careful not to overheat engine.
6) If NG, go to ªDiagnostic Procedureº, EC-3494.

Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along
with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal
collision. The SRS system composition which is available to NISSAN MODEL D22 is as follows (The com-
position varies according to the destination and optional equipment.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), seat belt pre-tensioner, 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:
+To 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.
+Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and
Air Bag Module, see the RS section.
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow harness connector.
