AUTO ACTIVE TEST
Description
In auto active test mode, the IPDM
E/R sends a drive signal to the follo wing systems to check their operation.
• Front wiper (LO, HI)
• Front fog lamps
• Parking lamps
• Side marker lamps
• Tail lamps
• License plate lamps
• Daytime running lamps
• Headlamps (LO, HI)
• A/C compressor
• Cooling fans (LO, HI)
Operation Procedure
CAUTION:
Do not start the engine.
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield before hand.
NOTE:
• If auto active test mode cannot be actuat ed, check door switch system. Refer to DLK-100,
"Component Function Check".
• When auto active test mode has to be cancelled halfway through test, turn ignition switch OFF.
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)
2. Turn ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, press the front door switch LH 10 times. Then turn the ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. Af ter that the horn sounds once, and the auto active test
starts.
5. After a series of the following operations is repeated 3 times, auto active test is completed.
Inspection in Auto Active Test Mode
When auto active test mode is actuated, the following operation sequence is repeated 3 times.
*: Outputs duty ratio of 50% for 5 seconds → duty ratio of 100% for 5 seconds on the cooling fan control module.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951597
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 t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 mi nutes before performing any service.
Precaution for WorkINFOID:0000000009461621
• When removing or disassembling each component, be ca reful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a shop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusabl e part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
-Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.

How to Handle BatteryINFOID:0000000009460432
CAUTION:
• If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.
• After connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.
• Never add distilled water through the hole used to check specific gravity.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharging a battery.
• The battery surface (particularly its top) should always be kept
clean and dry.
• The terminal connections should be clean and tight.
• At every routine maintenance, check the electrolyte level. This also applies to batteries designated as “low maintenance” and
“maintenance-free”.
• When the vehicle is not going to be used over a long period of time, disconnect the battery cable from the negative terminal. (If
the vehicle has an extended storage switch, turn it off.)
Work FlowINFOID:0000000009460433
BATTERY DIAGNOSIS WITH EXP-800 NI OR GR8-1200 NI
To diagnose and confirm the condition of the batte ry, use the following special service tools:
• EXP-800 NI Battery and electrical diagnostic analyzer
• GR8-1200 NI Multitasking battery and electrical diagnostic station
NOTE:
Refer to the applicable Instruction Manual for proper battery diagnosis procedures.

Checking Electrolyte Level
WARNING:
Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, never touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush wit h water for 15 minutes and seek medical attention.
Failure to do this may cause personal injury or damage to clothing or the painted surfaces.
