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 relatedincident.
2. Check the current need for scheduled maintenance, especially for fuel filter and air cleaner filter. Refer to MA-4, “Peri-
odic Maintenance”.
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.
GO TO 2.
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.
GO TO 3.

Inspection and AdjustmentNJCL0006CLUTCH PEDAL INSPECTIONNJCL0006S03Pedal StrokeNJCL0006S0301Check clutch pedal stroke by using a 1–meter rule to measure the
total pedal stroke. Place end of rule onto the middle of the clutch
pedal pad. Place a book/clipboard on the driver’s seat to set a ref-
erence point, ensure the book/clipboard does not move during
pedal depression. Mark (A) the pedal fully up position on the rule.
Depress the clutch pedal and mark (B) the rule again next to the
reference point on the book/clipboard. Measure the distance
between the marks (A and B), this is the actual pedal stroke (S).
Check the specified pedal stroke in the table, adjust actual pedal
stroke if necessary (refer to“CLUTCH PEDAL ADJUSTMENT”).
NOTE:
Do not use steering wheel as a reference point, angle gives
incorrect reading.
Ensure there is no interference between the floor carpet and
clutch pedal when fully depressed.

Pedal Free PlayNJCL0006S0302Check pedal free play, if out of specification refer to“CLUTCH
PEDAL ADJUSTMENT”
Push on the clutch pedal until resistance is felt, and check the
distance the pedal moves.
