How to Set SRT Code INFOID:0000000004780388
To set all SRT codes, self-diagnoses for the SRT items must be performed one or more times. Refer to EC-90," Diagnosis Description " , “SYSTEM READINESS TEST (SRT) CODE”, “SRT Item”.
Each diagnosis may require a long period of actual driving under various conditions.
WITH CONSULT-III
Perform corresponding DTC CONFIRMATION PROCE DURE one by one based on Performance Priority in
the table on “SRT Item”.
WITHOUT CONSULT-III
The most efficient driving pattern in which SRT codes can be properly set is explained below. The driving pat-
tern should be performed one or more times to set all SRT codes. P2118 2118 ETC MOT-B1 — 1

PRECAUTIONS
Precaution for Supplemental Restraint Syst em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000004786987
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. 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 w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” 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 “SUPPLEMEN TAL RESTRAINT SYSTEM”.
• 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 3 minu tes before performing any service.
Precaution for Procedure without Cowl Top Cover INFOID:0000000004786988
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
On Board Diagnosis (OBD) S ystem of Engine and A/T INFOID:0000000004780394
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
• Be sure to turn the ignition sw itch OFF and disconnect the negative battery cable before any repair
or inspection work. The open/short circuit of re lated switches, sensors, solenoid valves, etc. will
cause the MIL to light up.
• Be sure to connect and lock the connectors secure ly after work. A loose (unlocked) connector will
cause the MIL to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
• Certain systems and components, especially those related to OBD, may use a new style slide-lock-
ing type harness connector. For descrip tion and how to disconnect, refer to PG-64, " Description " .PIIB3706J

Reference Value " .
• Handle mass air flow sensor carefully to avoid damage.
• Do not clean mass air flow senso r with any type of detergent.
• Do not disassemble electric throttle control actuator.
• Even a slight leak in the ai r intake system can cause serious
incidents.
• Do not shock or jar the camshaft position sensor (PHASE),
crankshaft position sensor (POS).
• After performing each TROUBLE DIAGNOSIS, perform DTC
CONFIRMATION PROCEDURE or Component Function
Check. The DTC should not be displayed in the DTC Confir-
mation Procedure if the repair is completed. The Component
Function Check should be a good result if the repair is com-
pleted.
• When measuring ECM signals with a circuit tester, never allow
the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
• Do not use ECM ground termina ls when measuring input/out-
put voltage. Doing so may result in damage to the ECM’s tran-
sistor. Use a ground other than ECM terminals, such as the
ground. SEF217U

• Do not depress accelerator pedal when starting.
• Immediately after starting, do not rev up engine unnecessar-
ily.
• Do not rev up engine ju st prior to shutdown.
• When installing C.B. ham radio or a mobile phone, be sure to
observe the following as it may adversely affect electronic
control systems depending on installation location.
- Keep the antenna as far as possible from the electronic con-
trol units.
- Keep the antenna feeder line more than 20 cm (8 in) away
from the harness of electronic controls.
Do not let them run para llel for a long distance.
- Adjust the antenna and feeder line so that the standing-wave
ratio can be kept smaller.
- Be sure to ground the radio to vehicle body.
