Checking Power Steering Fluid and LinesNLS0008E
Check fluid level in reservoir tank with engine off.
Use “HOT” range at fluid temperatures of 50 to 80
C (122 to 176F)
or “COLD” range at fluid temperatures of 0 to 30
C (32 to 86F).
CAUTION:
Do not overfill.
Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .

Check lines for improper attachment, leaks, cracks, dam-
age, loose connections, chafing and deterioration.
Check rack boots for accumulation of power steering fluid.
Axle and Suspension PartsNLS0008F
Check front and rear axle and suspension parts for excessive play,
cracks, wear or other damage.
Shake each wheel to check for excessive play.
Check wheel bearings for smooth operation.
Check axle and suspension nuts and bolts for looseness.
Check strut (shock absorber) for oil leakage or other damage.
Check suspension ball joint for grease leakage and ball joint
dust cover for cracks or other damage.

CONSULT-II Function (IPDM E/R)NKS004E6
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II BASIC OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, and then turn
the ignition switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “IPDM E/R” on “SELECT SYSTEM” screen.
If “IPDM E/R” is not indicated, refer to GI-40, "
CONSULT-II Data
Link Connector (DLC) Circuit" .
Inspection Item, Diagnosis Mode Description
SELF-DIAG RESULTS The IPDM E/R performs diagnosis of the CAN communication and self-diagnosis.
DATA MONITOR The input/output data of the IPDM E/R is displayed in real time.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
ACTIVE TEST The IPDM E/R sends a drive signal to electronic components to check their operation.

Auto Active TestNKS004E7
DESCRIPTION
In auto active test mode, operation inspection can be performed when IPDM E/R sends a drive signal to the
following systems:
Rear window defogger
Front wiper (LO, HI)
Tail lamps, parking lamps and license plate lamps
Front fog lamps
Headlamps (LO, HI)
A/C compressor (magnetic clutch)
Cooling fan
Oil pressure warning lamp
OPERATION PROCEDURE
1. Close hood and front door (passenger side), and then lift wiper arms away from windshield (to prevent
glass damage by wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn ignition switch OFF.
3. Turn ignition switch ON, and within 20 seconds, press driver's door switch 10 times (close other doors).
Then turn ignition switch OFF.
4. Turn ignition switch ON within 10 seconds after ignition switch OFF.
5. When auto active test mode is actuated, horn chirps once. Oil pressure warning lamp starts blinking.
6. After a series of operations is repeated three times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway, turn ignition switch OFF.
CAUTION:
Never start the engine.
If the engine starting operation is made, delete DTC on the self-diag results of CONSULT-II.
Refer to BL-81, "
CONSULT-II Application Items" .
Be sure to inspect GW-52, "Door Switch Check" when the auto active test cannot be performed.

REMOVAL
1. Remove engine undercover with a power tool.
2. If necessary, remove heat bracket.
3. Remove the three way catalyst (right bank) with a power tool. Refer to EX-3, "
EXHAUST SYSTEM" .
4. Put matching marks onto propeller shaft flange yoke and final
drive companion flange.
CAUTION:
For matching marks, use paint. Do not damage propeller
shaft flange and companion flange.
5. Remove the propeller shaft fixing bolts.
6. Remove propeller shaft from the front final drive and transfer.
INSPECTION
Inspect propeller shaft runout at measuring point. If runout
exceeds specifications, replace propeller shaft assembly. For
measuring point, refer to PR-4, "
Propeller Shaft Runout Measur-
ing Point" .
As shown in the figure, while fixing yoke on one side, check axial
play of joint. If outside the standard, replace propeller shaft
assembly.
Check propeller shaft for bend and damage. If damage is
detected, replace propeller shaft assembly.
CAUTION:
Do not disassemble joints.
INSTALLATION
Note the following, install in the reverse order of removal.
Align matching marks to install propeller shaft to final drive com-
panion flange, and then tighten to specified torque. Refer to PR-
4, "Components" .
CAUTION:
Do not reuse the bolts.
After assembly, perform a driving test to check propeller shaft
vibration. If vibration occurred, separate propeller shaft from
final drive or transfer. Reinstall companion flange after rotating it
by 90, 180, 270 degrees. Then perform driving test and check
propeller shaft vibration again at each point.
