DescriptionINFOID:0000000012432074
The starter motor magnetic switch is supplied with power when the ignition switch is turned to the START posi-
tion while the selector lever is in the P (Park) or N (Neutral) position.
Diagnosis ProcedureINFOID:0000000012432075
Regarding Wiring Diagram information, refer to
STR-10, "Wiring Diagram - With Intelligent Key System" or
STR-16, "
Wiring Diagram - Without Intelligent Key System".
CAUTION:
Perform diagnosis under the cond ition that engine cannot start by the following procedure.
1. Remove fuel pump fuse.
2. Crank or start the engine (where possi ble) until the fuel pressure is released.
1.CHECK “S” CONNECTOR CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect starter motor connector.
3. Shift selector lever to “P” (Park) or “N” (Neutral) position.
4. Check voltage between starter motor harness connector F28 and ground.
Is the inspection result normal?
YES >> “S” circuit is OK. Further inspection is necessary. Refer to STR-21, "Work Flow (With GR8-1200
NI)" or STR-25, "Work Flow (Without GR8-1200 NI)".
NO >> GO TO 2.
2.CHECK HARNESS CONTINUI TY (OPEN CIRCUIT)
1. Disconnect IPDM E/R connector.
2. Check continuity between starter motor harnes s connector F28 and the IPDM E/R harness connector
E43.
3. Check continuity between starter motor connector F28 terminal S and ground.
Is the inspection result normal?
YES >> Further inspection is necessary. Refer to STR-21, "Work Flow (With GR8-1200 NI)" or STR-25,
"Work Flow (Without GR8-1200 NI)".
NO >> Repair or replace the harness or connectors.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012431939
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 severi ty 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 inoper ative, 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 unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 mi nutes before performing any service.
Service Notice and Precautions for EPS SystemINFOID:0000000012431940
• Check the following item when performing the trouble diagnosis:
- Check for possible causes of the malfunction by inte rviewing the customer as to what conditions were
present when the symptom occurred.
- Check if the steering wheel and the EPS control unit are genuine parts.
- Check if the air pressure and size of each tire is correct.
- Check if the installation of the links and suspension components are correct.
- Check if the tires are worn evenly, indicating the wheel alignment is correct.
- Check if the installation of the steering column and t he steering gear are correct. Check for loose bolts, dam-
aged links, cracked boots and leaking grease, etc.
- Check for damage or modification to suspension or body resulting in increased weight or altered ground clearance.
- Check if the battery voltage is proper.
- Check the EPS control unit harness to be sure the harness connectors are fully seated.
• Before connecting or disconnecting the EPS control uni t harness connector, turn ignition switch “OFF” and
disconnect the battery cable from the negative terminal. Battery voltage is applied to the EPS control unit
even if ignition switch is turned “OFF”.

EPS Control UnitINFOID:0000000012431942
• EPS control unit (1) is installed to steering column assembly.
• EPS control unit performs an arithmetical operation on data, such as steering wheel turning force (sensor signal) from the torque
sensor, vehicle speed signal, etc. Then it generates an optimum
assist torque signal to the EPS motor according to the driving con-
dition.
• EPS control unit decreases the output signal to EPS motor while
extremely using the power steering function (e.g., full steering)
consecutively for protecting EPS motor and EPS control unit
(Overload protection control).
EPS Motor, Torque Sensor, Reduction GearINFOID:0000000012431943
EPS motor (1), torque sensor (2) and reduction gear (3) are installed
to steering column assembly.
EPS MOTOR
EPS motor provides the assist torque by the control signal from EPS control unit.
TORQUE SENSOR
Torque sensor detects the steering torque, and transmits the signal to EPS control unit.
REDUCTION GEAR
Reduction gear increases the assist torque provided from EPS motor with worm gears, and outputs to the col-
umn shaft.
3. ECM • Transmits mainly th
e following signal to EPS control unit via
CAN communication:
- Engine status signal
• For detailed installation location, refer to EC-14, "ENGINE
CONTROL SYSTEM : ComponentPartsLocation".
• Receives mainly the following signal from EPS control unit
via CAN communication:
- EPS torque signal

DIAGNOSIS SYSTEM (EPS CONTROL UNIT)
CONSULT FunctionINFOID:0000000012431944
FUNCTION
CONSULT can display each diagnostic item usi ng the diagnostic test modes shown following:
*: The following diagnosis information is cleared by erasing:
•DTC
• Freeze frame data (FFD)
ECU IDENTIFICATION
Displays the part number stored in the control unit.
