Basic InspectionNJEC0632Precaution:
Perform Basic Inspection without electrical or mechanical
loads applied;
+Headlamp switch is OFF,
+On vehicles equipped with daytime light systems, set
lighting switch to the 1st position to light only small
lamps.
+Air conditioner switch is OFF,
+Rear defogger switch is OFF,
+Steering wheel is in the straight-ahead position, etc.
1 INSPECTION START
1. Check service records for any recent repairs that may indicate a related problem.
2. Check the current need for scheduled maintenance, especially for fuel filter and air cleaner filter. Refer to MA-6, ªPeri-
odic Maintenanceº.
3. Open engine hood and check the following:
+Harness connectors for improper connections
+Vacuum hoses for splits, kinks, or improper connections
+Wiring for improper connections, pinches, or cuts
SEF142I
4. Start engine and warm it up to the normal operating temperature.

2 PREPARATION FOR CHECKING IDLE SPEED
With CONSULT-II
Connect CONSULT-II to the data link connector.
Without CONSULT-II
Install diesel tacho tester to the vehicle.

REPAIRING PROCEDURENJEL0078S021. Wipe broken heat wire and its surrounding area clean with a
cloth dampened in alcohol.
2. Apply a small amount of conductive silver composition to tip of
drawing pen.
Shake silver composition container before use.
3. Place ruler on glass along broken line. Deposit conductive sil-
ver composition on break with drawing pen. Slightly overlap
existing heat wire on both sides [preferably 5 mm (0.20 in)] of
the break.
SEL012D
4. After repair has been completed, check repaired wire for con-
tinuity. This check should be conducted 10 minutes after silver
composition is deposited.
Do not touch repaired area while test is being conducted.
SEL013D
5. Apply a constant stream of hot air directly to the repaired area
for approximately 20 minutes with a heat gun. A minimum dis-
tance of 3 cm (1.2 in) should be kept between repaired area
and hot air outlet. If a heat gun is not available, let the repaired
area dry for 24 hours.
