Reference Area
The Reference Area of the wiring diagram contains references to additional electrical reference pages at the
end of the instruction. If connector numbers and titles are shown in the Reference Area of the wiring diagram,
these connectors symbols are not shown in the Connector Area.
●
SMJ (Super Multiple Junction)
In a wiring diagram, the SMJ connectors include a letter of the alphabet in the terminal number. SMJ con-
nector numbers are shown in the Reference Area of the wiring diagram. SMJ terminal arrangement can
be found on the electrical reference pages at the end of the instruction. For terminal arrangement of these
connectors, refer to the “SMJ (SUPER MULTIPLE JUNCTION)” electrical reference page at the end of the
instruction.
●
Fuse block—Junction Box (J/B)
Fuse block—Junction Box (J/B) connector number is shown in the Reference Area of the wiring diagram.
For connector terminal and fuse arrangement, refer to the “FUSE BLOCK—Junction Box (J/B)” electrical
reference page at the end of the instruction.

Electrical units
Electrical unit connector symbols are shown in the Connector Area of the wiring diagram. However, when
there is not enough space to show the connector terminal arrangement in the Connector Area of the wir-
ing diagram, the electrical unit connector number is shown in the Reference Area of the wiring diagram.
For electrical unit connector terminal arrangement, refer to the “ELECTRICAL UNITS” electrical reference
page at the end of the instruction. Most of the electrical unit connectors on this page are shown from the har-
ness side forth connector.

How to Check Terminal
EAS0012K
CONNECTOR AND TERMINAL PIN KIT
Use the connector and terminal pin kits listed below when replacing connectors or terminals.
The connector and terminal pin kits contain some of the most commonly used NISSAN/INFINITI connectors
and terminals. For detailed connector and terminal pin replacement procedures, refer to the latest NISSAN/
INFINITI CONNECTOR AND TERMINAL PIN SERVICE MANUAL.
HOW TO PROBE CONNECTORS
Connector damage and an intermittent connection can result from improperly probing of the connector during
circuit checks.
The probe of a digital multimeter (DMM) may not correctly fit the connector cavity. To correctly probe the con-
nector, follow the procedures below using a “T” pin. For the best contact grasp the “T” pin using an alligator
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
contact space for probing.
MALE TERMINAL
Carefully probe the contact surface of each terminal using a “T” pin.
Do not bend terminal.
How to Check Enlarged Contact Spring of Terminal
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.
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.
Do not force the male terminal into the female terminal with
your hands.
