1.
Use the formula below to calculate drive pinion adjusting shim
thickness.
2.
Select the proper drive pinion adjusting shim. For selecting adjusting shim, refer to the latest parts infor-
mation.
CAUTION:
If unable to find a shim of desired thickness, use a shim with thickness closest to the calculated
value.
COMPANION FLANGE RUNOUT
Check for companion flange runout as follows:
• For companion flange face, fit a dial indicator (1) onto the compan-
ion flange face (inner side of the propeller shaft mounting bolt
holes). For inner side of the companion flange, fit a test indicator
(2) to the inner side of companion flange (socket diameter).
• Rotate companion flange to check for runout.
• If the runout value is outside the runout limit, follow the procedure
below to adjust.
- Check for runout while changing the phase between companion
flange and drive pinion by 90
°
step, and search for the position where the runout is the minimum.
- If the runout value is still outside of the limit after the phase has been changed, replace companion flange.
- If the runout value is still outside of the limit after companion flange has been replaced, possible cause will
be an assembly malfunction of drive pinion.

INSPECTION AFTER DISASSEMBLY
Drive Gear and Drive Pinion
• Clean up the disassembled parts.
• If the gear teeth never mesh or line-up correctly, determine the cause and adjust or replace as necessary.
• If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new drive
gear and drive pinion as a set.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000007577717
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING:
Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.

Description
Multi display unit
Transmits the ON/OFF status of each mode of the drive mode switch (NORMAL, SPORT, ECO) to
TCM (CVT models), ECM (M/T models), EPS control unit and the A/C auto amp via CAN commu-
nication.
ECM

SYSTEM DIAGRAM
• The multi display unit transmits the operation status of the drive mode switch to other units via CAN commu-
nication as the mode signal (refer below).
- NORMAL: ON/OFF
- SPORT: ON/OFF
- ECO: ON/OFF
• Based on the mode signals received from TCM (CVT models) or multi display unit (M/T models) via CAN
communication, ECM changes over the throttle position and other characteristics.
• Based on the mode signals received from the multi display unit via CAN communication, TCM changes over
the gear shift line and other characteristics.
• Based on the mode signals received from the multi display unit via CAN communication, EPS C/U changes
the steering assist characteristic.
• Based on the ECO mode signal received from the multi display unit via CAN communication, the A/C auto
amp changes over the set temperature correction.
CONTROL DESCRIPTION
• The drive mode switch in the controller of the multi display unit is used to change over the vehicle mode and
thus change the control characteristics for the engine, transaxle, steering, and air conditioner.
Function Apply List
• With the NORMAL mode as the base mode, the control of vehicle characteristics is changed over to the fol-
lowing modes.
- SPORT: The control characteristics for the engine, transaxle, and steering system are changed so that a
sporty feel is created in the driving behavior.
- ECO: The control characteristics for the engine, transaxle, and automatic air conditioner are changed to help
improve the practical fuel economy.

• The engine torque, engine power, boost pressure, and instantaneous fuel consumption are provided for
information purposes only. They are not intended to prompt the driver to adjust driving style. The readings
may be slightly delayed relative to the actual vehicle behaviors. This is not a malfunction.
• The voltmeter reading cannot be used as an indicator for battery replacement because it indicates the input
voltage to the multi display unit, not the battery voltage.
• The ECO information screen is operable only while the vehicle is stopped.
• If no time setting is performed, the daily and weekly fuel consumption history data are not displayed.
• The readings may differ from the actual values depending on driving conditions.
