CHASSIS AND BODY MAINTENANCEPFP:00100
Checking Exhaust SystemBLS0005T
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage, chafing or deterioration.

If anything is found, repair or replace damaged parts.
Checking A/T FluidBLS0009F
1. Warm up engine.
2. Check for A/T fluid leakage.
3. Before driving, A/T fluid level can be checked A/T at fluid tem-
peratures of 30 to 50°C (86 to 122°F) using “COLD” range on A/
T fluid level gauge.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c. Check A/T fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free
paper.
CAUTION:
When wiping away the A/T fluid level gauge, always use
lint-free paper, not a cloth one.
e. Re-insert A/T fluid level gauge into A/T fluid charging pipe as far
as it will go.
CAUTION:
Firmly fix the A/T fluid level gauge to the A/T fluid charging
pipe using a stopper attached.
f. Remove A/T fluid level gauge and note reading. If reading is at
low side of range, add ATF to the A/T fluid charging pipe.
CAUTION:
Do not overfill.
4. Drive vehicle for approximately 5 minutes in urban areas.

5. Recheck A/T fluid level at A/T fluid temperatures of 50 to 80°C (122 to 176°F) using “HOT” range on A/T
fluid level gauge.
CAUTION:

When wiping away the A/T fluid level gauge, always use lint-free paper, not cloth one.

Firmly fix the A/T fluid level gauge to the A/T fluid charging pipe using a stopper attached.
6. Check A/T fluid condition.

If ATF is very dark or smells burned, checking operation of A/
T. Flush cooling system after repair of A/T.

If ATF contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-37,
"RADIATOR" , CO-40, "RADIATOR (ALUMINUM TYPE)" .
7. Install the removed A/T fluid level gauge in the A/T fluid charging
pipe.
CAUTION:
Firmly fix the A/T fluid level gauge to the A/T fluid charging
pipe using a stopper attached.
Changing A/T FluidBLS0009G
1. Warm up ATF.
2. Stop engine.
3. Drain ATF from drain plug and refill with new ATF. Always refill same volume with drained ATF.
CAUTION:
Do not reuse drain plug gasket.
4. Run engine at idle speed for 5 minutes.
5. Check A/T fluid level and condition. Refer to MA-35, "
Checking A/T Fluid" . If ATF is still dirty, repeat steps
2 through 5.
Checking CVT FluidBLS0009H
Fluid level should be checked with the fluid warmed up to 50 to 80°C (122 to 176°F). The fluid level check pro-
cedure is as follows:
SAT638A
Fluid grade:
Genuine NISSAN ATF Matic Fluid D or equivalent.
Refer to MA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS"

1. Check for fluid leakage.
2. With the engine warmed up, drive the vehicle in an urban area.
When ambient temperature is 20°C (68°F), it takes about 10
minutes for the CVT fluid to warm up to 50 to 80°C (122 to
176°F).
3. Park the vehicle on a level surface.
4. Apply parking brake firmly.
5. With engine at idle, while depressing brake pedal, move shift
selector throughout the entire shift range.
6. Pull out the CVT fluid level gauge from the CVT fluid charging
pipe after pressing the tab on the CVT fluid level gauge to
release the lock.
7. Wipe fluid off the CVT fluid level gauge. Insert the CVT fluid
level gauge rotating 180° from the originally installed position,
then securely push the CVT fluid level gauge until it meets the
top end of the CVT fluid charging pipe.
CAUTION:
When wiping away the CVT fluid level gauge, always use
lint-free paper, not a cloth rag.
8. Place the selector lever in “P” or “N” and make sure the fluid
level is within the specified range.
CAUTION:
When reinstalling CVT fluid level gauge, insert it into the
CVT fluid charging pipe and rotate it to the original installa-
tion position until it is securely locked.
9. Check CVT fluid condition.

If CVT fluid is very dark or smells burned, check operation of
CVT. Flush cooling system after repair of CVT.

If CVT fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of CVT. Refer to CO-37,
"RADIATOR" .

CHARGING SYSTEMPFP:23100
System DescriptionBKS001MJ
The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times:

through 10A fuse (No. 36, located in the fuse and fusible link block)

to alternator terminal 4 (“S” terminal).
“B” terminal supplies power to charge the battery and operate the vehicle's electrical system. Output voltage is
controlled by the IC regulator at terminal 4 (“S” terminal) detecting the input voltage.
The charging circuit is protected by the 120A fusible link (letter A, located in the fusible link holder).
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied:

through 10A fuse [No. 14, located in the fuse block (J/B)]

to combination meter terminal 8 for the charge warning lamp.
Ground is supplied:

to combination meter terminal 22

through alternator terminal 3 (“L” terminal)

to alternator terminal “E”

through ground E2.
The charge warning lamp will illuminate. When the alternator is providing sufficient voltage with the engine
running, the ground is opened and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a malfunction is indicated.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate charge warning lamp, if any of the following symp-
toms occur while alternator is operating:

Excessive voltage is produced.

No voltage is produced.

Trouble DiagnosisBKS001ML
Before performing an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The alternator can be checked easily by referring to the Inspection
Table.

Before starting, inspect the fusible link.

Use fully charged battery.
WITH IC REGULATOR
NOTE:

If the inspection result is OK even though the charging system is malfunctioning, check the “B” terminal
connection (Check the tightening torque) and voltage drop.

Check condition of rotor coil, rotor slip ring, brush and stator coil. If necessary, replace malfunctioning
parts with new ones.
