Trouble Diagnoses with
Battery/Starting/Charging System Tester
NBSC0018CAUTION:
When working with batteries, always wear appropriate eye
protection.
NOTE:
ITo ensure a complete and thorough diagnosis, the battery,
starter and alternator test segments must be done as a set
from start to finish.
IIf battery surface charge is detected while testing, the tester
will prompt you to turn on the headlights to remove the surface
charge.
IIf necessary, the tester will prompt you to determine if the bat-
tery temperature is above or below 0ÉC (32ÉF). Choose the
appropriate selection by pressing the up or down arrow button,
then press ªENTERº to make the selection.

1. Turn off all loads on the vehicle electrical system. Clean or
repair as necessary.
2. Visually inspect the battery, battery terminals and cable ends
with ignition switch in ªOFFº position.
NOTE:
The contact surface between the battery terminals, cable ends and
tester leads must be clean for a valid test. A poor connection will
prevent testing and a ªCHECK CONNECTIONº message will
appear during the test procedures. If this occurs, clean the battery
post and terminals, reconnect them and restart the test.
3. Connect the red tester lead clamp to the positive battery
terminal, and the black to the negative terminal.

5. Locate the battery type and rating stamped or written on the
top case of the battery to be tested.
NOTE:
The battery type and rating will have either of the following.
CCA: Cold Cranking Amps (490 CCA, 550 CCA, etc.)
JIS: Japanese Industrial Standard.
Battery is stamped with a number such as:
80D26L: 80 (rank of output), D (physical size-depth), 26 (width
in cm). The last character L (post configuration) is not input into
the tester.
The tester requires the rating for the battery be entered exactly
as it is written or stamped on the battery. Do not attempt a CCA
conversion for JIS stamped batteries. JIS must be input
directly.
6. Using the arrow and ªENTERº keys alternately, select the bat-
tery type and rating.
NOTE:
The tester lists five choices; CCA, JIS, IEC, DIN, and EN. Only use
CCA or JIS.

7. Press ªENTERº to begin the test. Diagnosis results are dis-
played on the tester. Refer to ªDIAGNOSTIC RESULT ITEM

8. Press ªENTERº, then test output code is displayed. Record the
test output code on the repair order.
9. Toggle back to the ªDIAGNOSTIC SCREENº for test results.
NOTE:
IIf necessary, the tester will ask the user to determine if the
battery has just been charged. Choose the appropriate selec-
tion by pressing the up or down arrow button and then press
the ªENTERº button to make the selection.
IWhen testing a battery installed in a vehicle that has recently
been driven, select ªBEFORE CHANGEº.
IIf the battery has just been slow charged due to a ªCHARGE

ªBEFORE CHARGE/AFTER CHARGEº, select ªAFTER
CHARGEº.

Checking Gear Housing MovementNBST00081. Check the movement of steering gear housing during station-
ary steering on a dry paved surface.
IApply a force of 49 N (5 kg, 11 lb) to steering wheel to check
the gear housing movement.
Turn off ignition key while checking.
Movement of gear housing:
±2mm(±0.08 in) or less
2. If movement exceeds the limit, replace mount insulator after
confirming proper installation of gear housing clamps.

Adjusting Rack RetainerNBST0009IPerform this driving test on a flat road.
a) Check whether vehicle moves in a straight line when steering
wheel is released.
b) Check whether steering wheel returns to neutral position when
steering wheel is released from a slightly turned (approx. 20É)
position.
IIf any abnormality is found, correct it by resetting adjusting
screw.
Checking and Adjusting Drive BeltsNBST0010Refer to MA-13, ªChecking Drive Beltsº.

Checking Fluid LevelNBST0011Check fluid level.
Use the correct range of the dipstick depending on the fluid tem-
perature. Use the ªHOTº range at 50 to 80ÉC (122 to 176ÉF), or the
ªCOLDº range at 0 to 30ÉC (32 to 86ÉF).
CAUTION:
IDo not overfill.
IRecommended fluid is Genuine Nissan PSF II or equiva-
lent. Refer to MA-11, ªFluids and Lubricantsº.

Checking Fluid LeakageNBST0012Check the lines for improper attachment and for leaks, cracks,
damage, loose connections, chafing and deterioration.
1. Run engine between idle speed and 1,000 rpm.
Make sure temperature of fluid in oil tank rises to 60 to 80ÉC
(140 to 176ÉF).
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each ªlockº position for five seconds
and carefully check for fluid leakage.

2. Align spiral cable correctly when installing steering wheel.
a. Set the front wheels in the straight-ahead position.
b. Make sure that the spiral cable is in the neutral position.
The neutral position is detected by turning left about 2.5 revo-
lutions from the right end position. Align the two marks (
).
CAUTION:
IThe spiral cable may snap due to steering operation if the
cable is installed in an improper position.
IAlso, with the steering linkage disconnected, the cable
may snap by turning the steering wheel beyond the limited
number of turns. The spiral cable can be turned to the left
about 2.5 turns from the right end position.
