REAR SUSPENSION ASSEMBLY
Revision: 2006 January2006 M35/M45
THE ALIGNMENT PROCESS
IMPORTANT:
Use only the alignment specifications listed in this Service Manual.
When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
–The alignment specifications programmed into your machine that operate these indicators may not be cor-
rect.
–This may result in an ERROR.
Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). DO NOT use this “Rolling Compensation”
method.
–Use the “Jacking Compensation Method”. After installing the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
–See Instructions in the alignment machine you're using for more information on this.
CAMBER INSPECTION
Measure camber of both right and left wheels with a suitable alignment gauge.
Adjust in accordance with the following procedures.
If outside the standard value, adjust with adjusting bolt in front
lower link.
NOTE:
After adjusting camber, be sure to check toe-in.
TOE-IN
If toe-in is not within the specification, adjust with adjusting bolt in
rear lower link.
CAUTION:
Be sure to adjust equally on RH and LH side with adjusting bolt.
If toe-in is not still within the specification, inspect and replace any
damaged or worn rear suspension parts.Standard value

CONSULT-II Function (PRECRASH SEATBELT)NHS00085
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II INSPECTION PROCEDURE
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. Turn ignition switch “OFF”.
2. Connect “CONSULT-II” and “CONSULT-II CONVERTER” to the
data link connector (1).
3. Turn ignition switch “ON”.
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “PRECRASH SEATBELT”.
If “PRECRASH SEATBELT” is not indicated, refer to GI-40,
"CONSULT-II Data Link Connector (DLC) Circuit" .

Preliminary CheckNHS00086
PRE-CRASH SEAT BELT OPERATION INSPECTION
WAR NING :
The following tests should be performed in a safe, open place that is free of traffic and obstacles.
The tests should be performed on a dry, paved road. Do not attempt the tests on wet or unpaved
road, open road, or highway. (This may cause an accident or personal injury.)
Driver and passenger assume it will not operate and prepare themselves accordingly.
1. Tighten driver and passenger seat belts.
2. Drive at approximately 25 km/h (16 MPH).
3. Notify passenger of a sudden stop. Driver and passenger prepare themselves for the possibility of
system not operating. Then, driver fully depresses the brake pedal to stop suddenly.
4. Make sure that the shoulder of the seat belt is pulled while braking.
