Electrical Connectors - Inspect

Most electrical faults are caused by poor connections.
The following procedure will assist in detecting faults
with connectors and with wiring. If a fault is found,
correct the condition and verify that the fault is
resolved.
Intermittent electrical faults are sometimes resolved
by disconnecting and reconnecting connectors. It is
very important to check for diagnostic codes
immediately before disconnecting a connector. Also
check for diagnostic codes after reconnecting the
connector. If the status of a diagnostic code is
changed due to disconnecting and reconnecting a
connector, there are several possible reasons. The
likely reasons are loose terminals, improperly
crimped terminals, moisture, corrosion, and
inadequate mating of a connection.
Follow these guidelines:
• Never break the insulation of a wire in order to
access a circuit for measurements.
• If a wire is cut, always install a new terminal for the
repair.
The connection of any electrical equipment and
the disconnection of any electrical equipment
may cause an explosion hazard which may result
in injury or death. Do not connect any electrical
equipment or disconnect any electrical equipment
in an explosive atmosphere.
