STEERING WHEEL TURNING FORCE IS HEAVY OR LIGHT
Diagnosis ProcedureINFOID:0000000009460376
1.PERFORM SELF-DIAGNOSIS
With CONSULT
Perform “EPS” self-diagnosis.
Is a malfunctioning system displayed?
YES >> Check malfunctioning system. Refer to STC-13, "DTC Index".
NO >> GO TO 2.
2.CHECK THE POWER STEERING CONTROL MODULE SIGNAL (1)
With CONSULT
1. Start the engine. CAUTION:
Never drive the vehicle.
2. Turn the steering wheel until it stops.
3. Select “MTR ASSIST” in “DATA MONITOR” of “EPS”.
Is the display value
“100%”?
YES >> GO TO 4.
NO >> GO TO 3.
3.CHECK THE POWER STEERING CONTROL MODULE SIGNAL (2)
With CONSULT
1. Select “C/U TEMP” and “C/U TEMP A” in “DATA MONITOR” of “EPS”.
2. Stop the system until the DATA MONITOR display value drops to “90 °C (194 °F)” or less.
3. Check whether symptom continues.
Did symptom continue?
YES >> GO TO 4.
NO >> This occurs because the protection function lowers the assist force. It is not a system malfunction.
Inspection End.
4.CHECK THE POWER STEERING CONTROL MODULE SIGNAL (3)
With CONSULT
1. Turn the steering wheel to the straight -ahead position. (There is no steering force)
2. Select “BATTERY VOLT” in “DATA MONITOR” of “EPS”.
Is the display value
“10.5 V” or more?
YES >> GO TO 5.
NO >> Check the battery power system. Refer to STC-23, "Diagnosis Procedure"
.
5.CHECK THE POWER STEERING CONTROL MODULE SIGNAL (4)
With CONSULT
Select “ESTM VHCL SPD” in “DATA MONITOR” of “EPS”.
*: This may not agree with the speedometer indication imm ediately after the ignition switch is turned ON. This
is not a malfunction.
Is the check result normal?
YES >> GO TO 6.
NO >> Check the combination meter, ABS actuator and electric unit (control unit). Refer to MWI-18,
"CONSULT Function (METER/M&A)" and BRC-33, "CONSULT Function (ABS)".
Monitor item Test condition Display value
ESTM VHCL SPD When stopped 0.00 km/h or mph
While driving Approximately equal to the in-
dication on speedometer

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951694
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 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 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 NISS AN/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.
