When the connector is plugged in, it can be pushed in
until it "clicks" and locks.
When disassembling the connector, be sure to hold the
connector and do not pull the lead.
Inspect each terminal on the connector / coupler
for looseness or bending

Inspect each lead wire circuit for poor connection by
shaking it by hand lightly. If any abnormal condition is
found,
repair or replace.As in Fig.6.1.3
When taking measurements at electrical connectors
using a tester probe, be sure to insert
the probe from the wire harness side (backside) of the
connector / coupler.
As in Fig.6.1.4
•When connecting meter probe from the terminal side
of the coupler (connection from harness side not being
possible), use extra care not to force and cause the male
terminal to bend or the female terminal to open. As in
Fig.6.1.5,Connect the probe as shown to avoid opening of
female terminal.
