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.

DIAGNOSIS DESCRIPTION
DIAGNOSIS DESCRIPTION : 1 Tr ip Detection Diagnosis and 2 Trip Detection Diagno-
sis
INFOID:0000000009463996
NOTE:
“Start the engine and turn OFF the ignition switch after warm-up.” This is defined as 1 trip.
1 TRIP DETECTION DIAGNOSIS
When initial malfunction is detected, TCM memorize s DTC. In these diagnoses, some illuminate MIL and
some do not. Refer to TM-60, "DTC Index"
.
2 TRIP DETECTION DIAGNOSIS
When initial malfunction is detected, TCM memorizes DTC of the 1st trip. MIL does not light at this stage. <1
trip>
If the same malfunction is detected again in next drivi ng, TCM memorizes DTC. When DTC is memorized, MIL
lights. <2 trip>
“Trip” of the “2 trip detection diagnosis” indicates the driving mode that executes self-diagnosis during driving.
×: Check possible —: Check not possible
DIAGNOSIS DESCRIPTION : DTC and DTC of 1st TripINFOID:0000000009463997
2 TRIP DETECTION DIAGNOSIS THAT ILLUMINATES MIL
• The DTC number of the 1st trip is the same as the DTC number.
• When a malfunction is detected at the 1st trip, TCM memo rizes DTC of the 1st trip. MIL does not light at this
stage. If the same malfunction is not detected at t he 2nd trip (conforming to necessary driving conditions),
DTC at the 1st trip is erased from TCM. If the same malfunction is detected at the 2nd trip, TCM memorizes
DTC and MIL lights at the same time.
• The DTC of the 1st trip is specified in Service $01 of SAE J1979/ISO 15031-5. Since detection of DTC at the
1st trip does not illuminate MIL, warning for a problem is not given to a driver.
• For procedure to delete DTC and 1st trip DTC from TCM, refer to TM-43, "CONSULT Function"
.
• If DTC of the 1st trip is detected, it is necessary to check the cause according to the “Diagnosis flow”. Refer
to TM-77, "Flowchart of Trouble Diagnosis"
.
DIAGNOSIS DESCRIPTION : Malf unction Indicator Lamp (MIL)INFOID:0000000009463998
• TCM not only detects DTC, but also sends the MI L signal to ECM through CAN communication. ECM sends
the MIL signal to the combination meter through CAN communication according to the signal, and illumi-
nates MIL.
• For malfunction indicator lamp (MIL) description, refer to EC-74, "DIAGNOSIS DESCRIPTION : Malfunction
Indicator Lamp (MIL)".
DIAGNOSIS DESCRIPTION : Counter SystemINFOID:0000000009463999
RELATION BETWEEN DTC AT 1ST TRIP/DTC/MIL AND DRIVING CONDITIONS (FOR 2 TRIP DE-
TECTION DIAGNOSIS THAT ILLUMINATES MIL)
• When initial malfunction is detected, TCM memorizes DT C of the 1st trip. MIL does not light at this stage.
• If the same malfunction is detect ed at the 2nd trip, TCM memorizes DTC and MIL lights at the same time.
• Then, MIL goes after driving the vehicle for 3 tr ips under “Driving condition B” without malfunction.
• DTC is displayed until 40 trips of “Driving condition A” are satisfied without detecting the same malfunction.
DTC is erased when 40 trips are satisfied.
