Never drive the vehicle.
2. Select “ASSIST LEVEL” in “Data Monitor” of “EPS”.
Does the item in
“Data Monitor” indicate 100%?
YES >> GO TO 6.
NO >> GO TO 4.
4.CHECK EPS CONTROL UNIT SIGNAL (2)
With CONSULT
Select “BATTERY VOLT” in “Data Monitor” of “EPS”.
Does the item in
“Data Monitor” indicate 10 V or more?
YES >> GO TO 5.
NO >> Perform trouble diagnosis of EPS control unit power supply and ground. Refer to STC-18, "
Diag-
nosis Procedure".
5.CHECK EPS CONTROL UNIT SIGNAL (3)
With CONSULT
1. Select “ASSIST LEVEL” in “Data Monitor” of “EPS”.
2. Stop the EPS system until the item in “Data Monitor” becomes “100%”.
NOTE:
While stopping the EPS system, do not turn steering wheel.
3. Check that the symptom continues.
Does the symptom continue?
YES >> GO TO 6.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012430493
The Supplemental Restraint System such as “A IR 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. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c 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 three minutes before performing any service.
Service Notice or Precautions for Steering SystemINFOID:0000000012430494
• In case of removing the steering gear, make the final tightening with grounded and unloaded vehicle condi- tion, and then check wheel alignment.
• Observe the following precautions when disassembling.
- Before disassembly, thoroughly clean the outside of the unit.
- Disassembly should be done in a clean work area. It is im portant to prevent the internal parts from becoming
contaminated by dirt or other foreign matter.
- For easier and proper assembly, place disassembled parts in order on a parts rack.
- Use nylon cloth or paper towels to clean the parts; co mmon shop rags can leave lint that might interfere with
their operation.
- Do not reuse non-reusable parts.
- Before assembling, apply the specified grease to the directed parts.
FOR ELECTRIC POWER STEERING (EPS)
• During quick steering, rasping noise may be heard from around the steering wheel. This is not a malfunction.
The noise is an operating noise of the EPS system under normal conditions. If the rasping noise occurs dur-
ing slow steering, this may not be an operating noise of the system. In this case, it is necessary to find out
the location of the noise and repair, if necessary.
• Do not repeat static steering. (Mot or and EPS control unit could be heated.)

INSPECTION AFTER INSTALLATION
• Check the operation of the control linkage. Refer to TM-21, "Inspection".
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
Fluids and Lubricants".
• Use procedure below to check for fuel leaks.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks at connection points.
• Start engine. With engine speed increased, check again for fuel leaks at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no lea ks of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.
