1998 NISSAN PICK-UP check engine

CONSULT Inspection Procedure
SELF-DIAGNOSIS PROCEDURE
1) Turn ignition switch OFF.
2) Connect CONSULT to Data Link Con-
nector for CONSULT.
1) Start engine.
2) Drive vehicle over 30 km/h (19 MPH)
for at least one minute.
1) Stop vehicle with engine running
and touch ``START'' on CONSULT
screen.
2) Touch ``ABS''.
3) Touch ``SELF-DIAG RESULTS''.
lThe screen shows the detected mal-
function and how many times the igni-
tion switch has been turned since the
malfunction.
Make the necessary repairs following the
diagnostic procedures.
After the malfunctions are repaired, erase
the self-diagnostic results stored in the
control unit by touching ``ERASE''.
Check warning lamp for deactivation after
driving vehicle over 30 km/h (19 MPH) for
at least one minute.
Test the ABS in a safe area to verify that
it functions properly.
Note: ``SELF-DIAG RESULTS'' screen shows the detected malfunction and
how many times the ignition switch has been turned since the mal-
function.

TROUBLE DIAGNOSES FOR SYMPTOMS
BR-74

Note: ABS may operate and cause vibration under any of the
following conditions.
lApplying brake gradually when shifting or operating
clutch.
lLow friction (slippery) road.
lHigh speed cornering.
lDriving over bumps and pot holes.
lEngine speed is over 5,000 rpm with vehicle stopped.
Diagnostic Procedure 12 (Warning lamp does
not come on when ignition switch is turned
ON.)
CHECK FUSE.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Check 10A fuse . For fuse layout, refer to
POWER SUPPLY ROUTING in EL sec-
tion.
OK
cNG
Replace fuse.
CHECK WARNING LAMP ACTIVATE.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Disconnect ABS actuator and electric unit
connector.
Does the warning lamp activate?
No
cYes
VA(Go to next page.)
CHECK HARNESS FOR SHORT.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Disconnect ABS actuator and electric
unit connector.
2. Check voltage between ABS actuator
and electric unit connector
E4(body
side) terminal
V10(2WD) orV21(4WD)
and ground.
Battery voltage should not exist.
OK
cNG
Repair harness or connec-
tor.
CHECK COMBINATION METER.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Clutch Disc and Flywheel
INSPECTION
lCheck clutch disc for burns, discoloration or oil or grease
leakage. Replace if necessary.
lCheck clutch disc for wear of facing.
Wear limit of facing surface to rivet head:
0.3 mm (0.012 in)

250 37.0 - 39.0 mm (1.457 - 1.535 in)
lCheck thrust rings for wear or damage by shaking cover
assembly up and down to listen for chattering noise, or lightly
hammering on rivets for a slightly cracked noise. Replace
clutch cover assembly if necessary.
lCheck pressure plate and clutch disc contact surface for
slight burns or discoloration. Repair pressure plate with
emery paper.
lCheck pressure plate and clutch disc contact surface for
deformation or damage. Replace if necessary.
INSTALLATION
lInsert Tool into clutch disc hub while installing clutch cover
and disc.
lBe careful not to allow grease to contaminate clutch facing.
lTighten bolts in numerical order, in two steps.
First step:
:10-20Nzm (1.0 - 2.0 kg-m,7-14ft-lb)
Final step:
:22-29Nzm (2.2 - 3.0 kg-m, 16 - 22 ft-lb)
