NORMAL OPERATING CONDITION

NORMAL OPERATING CONDITION

COMPASS

COMPASS : Description

INFOID:0000000001702322

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-21, 

"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-21, "Description"

.

Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSION-
ER"

INFOID:0000000001702323

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.
