PRECAUTIONS FOR SUPPLEMENTAL RESTRAINT SYSTEM (SRS) "AIR BAG" AND "SEAT BELT PRE-TENSIONER"
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. See AIR BAG RESTRAINT SYSTEMS .
| 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 AIR BAG RESTRAINT SYSTEMS . Do not use electrical test equipment on any circuit related to the SRS unless instructed to. SRS wiring harnesses can be identified by yellow and/or orange harness connectors. |
How to Handle Battery
| 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.
Scheme 57
Scheme 58
Scheme 59
- 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 negative battery terminal.
- Check the charge condition of the battery. Periodically check the specific gravity of the electrolyte. Keep a close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
| WARNING | Do not allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touching a battery, do not touch or rub your eyes until you have thoroughly washed your hands. If acid contacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention. |
Scheme 60
- Remove the cell plug using a suitable tool.
- Add distilled water up to the MAX level.
Sulphation
A battery will be completely discharged if it is left unattended for a long time and the specific gravity will become less than 1.100. This may result in sulphation on the cell plates.
To determine if a battery has been "sulphated", note its voltage and current when charging it. As shown in the figure, less current and higher voltage are observed in the initial stage of charging sulphated batteries.
A sulphated battery may sometimes be brought back into service by means of a long, slow charge, 12 hours or more, followed by a battery capacity test.
Scheme 61
Scheme 62
- Read hydrometer and thermometer indications at eye level.
- Use the chart below to correct your hydrometer reading according to electrolyte temperature.

CHARGING THE BATTERY
| CAUTION | Do not "quick charge" a fully discharged battery. Keep the battery away from open flame while it is being charged. When connecting the charger, connect the leads first, then turn on the charger. Do not turn on the charger first, as this may cause a spark. If battery electrolyte temperature rises above 60°C (140°F), stop charging. Always charge battery at a temperature below 60°C (140°F). |
Scheme 66
Do not charge at more than 50 ampere rate.
Note. The ammeter reading on your battery charger will automatically decrease as the battery charges. This indicates that the voltage of the battery is increasing normally as the state of charge improves. The charging amps indicated above refer to initial charge rate. If, after charging, the specific gravity of any two cells varies more than .050, the battery should be replaced.
M/T MODEL
Power is supplied at all times
- Through 40A fusible link (letter m , located in the fuse and fusible link box)
- To ignition switch terminal B.
With the ignition switch in the START position, power is supplied
- From ignition switch terminal St
- To intelligent power distribution module engine room (IPDM E/R) terminal 11.
With the ignition switch in the ON or START position, power is supplied
- Through 10A fuse [No. 12, located in the fuse block (J/B)]
- To intelligent power distribution module engine room (IPDM E/R) terminal 43.
When the clutch pedal is depressed, ground is supplied to intelligent power distribution module engine room (IPDM E/R) terminal 46 through the clutch interlock switch and body grounds E15 and E24.
Provided that the intelligent power distribution module (IPDM E/R) receives a starter relay on signal from the BCM over the CAN lines, the IPDM E/R is energized and power is supplied
- From terminal 4 of the clutch interlock relay
- To terminal S of the starter motor windings.
The starter motor plunger closes and provides a closed circuit between the battery and the starter motor. The starter motor is grounded to the cylinder block. With power and ground supplied, the starter motor operates. In the event that the CAN communication line fails, the IPDM E/R will continue to receive a starter relay on signal from the BCM as long as the ignition switch remains in the START or ON positions.

Pinion/Clutch Check
- Inspect pinion assembly teeth. Replace pinion assembly if teeth are worn or damaged. (Also check condition of ring gear teeth.)
- Inspect planetary gears/planetary gear teeth. Replace planetary gears/planet gears if teeth are worn or damaged. (Also check condition of pinion shaft/drive shaft gear teeth.)
- Check to see if pinion assembly locks in one direction and rotates smoothly in the opposite direction. If it locks or rotates in both directions, or if unusual resistance is evident, replace.
