SERVICE INFORMATION FOR ELECTRICAL INCIDENT

GI-39

< BASIC INSPECTION >

• Do not apply excessive shock to the control unit by dropping or hit-

ting it.

• Be careful to prevent condensation in the control unit due to rapid

temperature changes and do not let water or rain get on it. If water

is found in the control unit, dry it fully and then install it in the vehi-

cle.

• Be careful not to let oil to get on the control unit connector.

• Avoid cleaning the control unit with volatile oil.

• Do not disassemble the control unit, and do not remove the upper

and lower covers.

• When using a DMM, be careful not to let test probes get close to

each other to prevent the power transistor in the control unit from

damaging battery voltage because of short circuiting.

• When checking input and output signals of the control unit, use the

specified check adapter.

How to Check Terminal

INFOID:0000000011278277

HARNESS REPAIR KIT

• Use the harness repair kit J-48817 shown below when replacing connectors or terminals.

• The harness repair kit contains some of the most commonly used NISSAN/INFINITI connectors and termi-

nals. For detailed connector and terminal pin replacement procedures, refer to the J-48817 User Guide.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

• Connector damage and an intermittent connection can result from improperly probing of the connector dur-

ing circuit checks.

• The probe of a digital multimeter (DMM) may not correctly fit the connector cavity. To correctly probe the

connector, follow the procedures below using a “T” pin. For the best contact grasp the “T” pin using an alliga-

tor clip.

Probing from Harness Side

Standard type (not waterproof type) connector should be probed

from harness side with “T” pin.

• If the connector has a rear cover such as a ECM connector,

remove the rear cover before probing the terminal.

• Do not probe waterproof connector from harness side. Damage to

the seal between wire and connector may result.

Probing from Terminal Side

FEMALE TERMINAL

• There is a small notch above each female terminal. Probe each

terminal with the “T” pin through the notch.

Do not insert any object other than the same type male terminal

into female terminal.

• Some connectors do not have a notch above each terminal. To

probe each terminal, remove the connector retainer to make con-

tact space for probing.

MALE TERMINAL

• Carefully probe the contact surface of each terminal using a “T”

pin.

CAUTION:

Dot not bend terminal.

How to Check Enlarged Contact Spring of Terminal

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

GI-41

< BASIC INSPECTION >

• An enlarged contact spring of a terminal may create intermittent signals in the circuit.

• If the intermittent open circuit occurs, follow the procedure below to inspect for open wires and enlarged con-

tact spring of female terminal.

1. Assemble a male terminal and approx. 10 cm (3.9 in) of wire.

NOTE:

Use a male terminal which matches the female terminal.

2. Disconnect the suspected faulty connector and hold it terminal

side up.

3. While holding the wire of the male terminal, try to insert the male

terminal into the female terminal.

CAUTION:

Do not force the male terminal into the female terminal with

your hands.

4. While moving the connector, check whether the male terminal

can be easily inserted or not.

• If the male terminal can be easily inserted into the female ter-

minal, replace the female terminal.

Waterproof Connector Inspection

If water enters the connector, it can short interior circuits. This may lead to intermittent problems.

Check the following items to maintain the original waterproof characteristics.

RUBBER SEAL INSPECTION

GI-42

< BASIC INSPECTION >

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

• Most waterproof connectors are provided with a rubber seal

between the male and female connectors. If the seal is missing,

the waterproof performance may not meet specifications.

• The rubber seal may come off when connectors are disconnected.

Whenever connectors are reconnected, make sure the rubber seal

is properly installed on either side of male or female connector.

WIRE SEAL INSPECTION

• The wire seal must be installed on the wire insertion area of a

waterproof connector. Be sure that the seal is installed properly.

Terminal Lock Inspection

Check for unlocked terminals by pulling wire at the end of connector.

An unlocked terminal may create intermittent signals in the circuit.

How to Repair Aluminum Wires

INFOID:0000000011278278

PRECAUTIONS FOR THE HANDLING OF ALUMINUM WIRES

• If an aluminum wire is damaged (e.g. broken), never perform the repair method for copper wires (soldering).

• Never perform electrotap for connecting broken aluminum wires.

• To secure the wire fixing strength (a force to protect aluminum wire from being disconnected from crimp ter-

minal) and electrical conductivity, always use the dedicated harness repair kit and crimping tool [SST: J-

48817-AL-KIT] when repairing broken wires.

HOW TO DISTINGUISH ALUMINUM WIRES

Wiring color: Lavender (Color code: LA)

HOW TO REPAIR BROKEN WIRES

1. Insert heat shrinkable tube into the target aluminum wire

beforehand.

2. Strip wire protector approximately 10 mm and insert it into crimp

terminal .

CAUTION:

Check wire size and use appropriate crimp terminal.
