Nissan Primera P11. Instruction — part 453
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 connector symbols are not shown
in the Connector Area.
Super multiple junction (SMJ)
In a wiring diagram, the SMJ connectors include a letter of the
alphabet in the terminal number. SMJ connector numbers are
shown in the Reference Area of the wiring diagram. SMJ termi-
nal arrangement can be found on the electrical reference pages
at the end of the instruction. For terminal arrangement of these
connectors, refer to “SUPER MULTIPLE JUNCTION (SMJ)”
electrical reference page at the end of the instruction.

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 connector, 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 ter-
minal.
●
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 contact 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 termi-
nal 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.
4. While moving the connector, check whether the male termi-
nal can be easily inserted or not.
●
If the male terminal can be easily inserted into the female
terminal, replace the female terminal.
