THE OIL PRESSURE WARNING LAMP DOES NOT TURN OFF

Description

INFOID:0000000009483238

The oil pressure warning lamp remains illuminated while the engine is running (normal oil pressure).

Diagnosis Procedure

INFOID:0000000009483239

Regarding Wiring Diagram information, refer to 

MWI-61, "Wiring Diagram"

.

1.

CHECK OIL PRESSURE WARNING LAMP

Perform IPDM E/R auto active test. Refer to 

PCS-9, "Diagnosis Description"

.

Is oil pressure warning lamp illuminated?

YES

>> GO TO 2

NO

>> Replace combination meter. Refer to 

MWI-84, "Removal and Installation"

.

2.

1. Turn ignition switch OFF.

2. Disconnect the oil pressure switch connector.

3. Turn ignition switch ON. 

4. Check voltage between the oil pressure switch harness connec-

tor E208 terminal 1 and ground.

Is the inspection result normal?

YES

>> GO TO 3

NO

>> GO TO 4

3.

CHECK OIL PRESSURE SWITCH

Perform a unit check for the oil pressure switch. Refer to 

MWI-36, "Component Inspection"

.

Is the inspection result normal?

YES

>> Replace IPDM E/R. Refer to 

PCS-27, "Removal and Installation"

.

NO

>> Replace oil pressure switch.

4.

CHECK OIL PRESSURE SWITCH SIGNAL CIRCUIT

Check the oil pressure switch signal circuit. Refer to 

MWI-36, "Diagnosis Procedure"

.

Is the inspection result normal?

YES

>> Replace IPDM E/R. Refer to 

PCS-27, "Removal and Installation"

.

NORMAL OPERATING CONDITION

COMPASS
COMPASS : Description

INFOID:0000000009483240

COMPASS

• The electronic compass is highly protected from changes in most magnetic fields. However, some large

changes in magnetic fields can affect it. Some examples are (but not limited to): high tension power lines,

large steel buildings, subways, steel bridges, automatic car washes, large piles of scrap metal, etc. While

this does not happen very often, it is possible.

• During normal operation, the Compass Mirror will continuously update the compass calibration to adjust for

gradual changes in the vehicle's magnetic "remnant" field. If the vehicle is subjected to high magnetic influ-

ences, the compass may appear to indicate false headings, become locked, or appear that it is unable to be

calibrated. If this occurs, perform the calibration procedure.

• If at any time the compass continually displays the incorrect direction or the reading is erratic or locked, ver-

ify the correct zone variance.

Symptom Chart

Symptom

Cause

Solution / Reference

The compass display reads "C".

• Compass is not calibrated.
• Incorrect zone variance setting.
• Large change in magnetic field (Steel 

bridges, subways, concentrations of 
metal, car washes, etc.)

• Compass was calibrated incorrectly or 

in the presence of a strong magnetic 
field.

Perform Calibration. Refer to 

MWI-22, 

"Description"

.

Compass shows the wrong direction.

Compass does not change direction ap-
pears "Locked".

Compass does not show all the directions, 
one or more is missing.

The compass was calibrated but it "loses" 
calibration.

On long trips the compass shows the 
wrong direction.

Perform Zone Variation Setting if correct 
reading is desired in that location. Refer to 

MWI-22, "Description"

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000010208477

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 SR and SB section of this Service Man-

ual.

WARNING:

• To avoid rendering the SRS inoperative, 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 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 the SR section.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Service Manual. SRS wiring harnesses 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 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 three minutes before performing any service.
