2. Check the operation of the brake warning lamp by operating the parking brake.
Parking brake applied : ON

Parking brake released : OFF
YES >> Replace the combination meter.
NO >> GO TO 2.
2.CHECK PARKING BRAKE SWITCH SIGNAL CIRCUIT
Perform a check for the parking brake switch signal circuit. Refer to MWI-65, "Diagnosis Procedure".
YES >> GO TO 3.
3.CHECK PARKING BRAKE SWITCH UNIT
Perform a unit check for the parking brake switch. Refer to BRC-77, "Component Inspection".
NO >> Replace the parking brake switch. Refer to PB-5, "Removal and Installation".

Check that the headlamps operate normally by operating the combination switch (light switch).
Do they operate normally?
D
YES >> GO TO 2.
NO >> Refer to EXL-183, "Diagnosis Procedure".
2.CHECK FRONT DOOR SWITCH (DRIVER SIDE) SIGNAL CIRCUIT E
Perform the check for the front door switch (driver side) signal circuit. Refer to DLK-63, "Diagnosis Procedure".

2. Check the operation of the seat belt warning lamp in the combination meter.
Seat belt fastened : OFF

Seat belt not fastened : ON
YES >> GO TO 2.
NO >> GO TO 4.
Check the buckle switch input signal with the “Data Monitor”. Refer to WCS-24,
"Component Function Check".
YES >> Replace the unified meter and A/C amp.
NO >> GO TO 3.
3.CHECK SEAT BELT BUCKLE SWITCH CIRCUIT
Perform the check for the seat belt buckle switch circuit. Refer to WCS-24, "Diagnosis Procedure".
YES >> Replace the unified meter and A/C amp.
4.CHECK SEAT BELT BUCKLE SWITCH UNIT
Perform a unit check for the seat belt buckle switch. Refer to WCS-25, "Component Inspection".
NO >> Replace the seat belt buckle. Refer to SB-7, "SEAT BELT BUCKLE : Removal and Installation".

PRECAUTIONS
< PRECAUTION >
PRECAUTION A
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT B
PRE-TENSIONER" INFOID:0000000003733159
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along C
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. D
Information necessary to service the system safely is included in the “SRS AIRBAG” and “SEAT BELT” of this
Service Manual.
WARNING: E
• 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.
F
• 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 “SRS AIRBAG”.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this G
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
