Intermittents and Poor Connections

Most intermittents are caused by faulty electrical connections or
wiring. When a check for proper connection is requested in a
diagnostic flow table, perform careful check of suspect circuits for:
• Poor mating of connector halves, or terminals not fully
seated in the connector body (backed out).
• Dirt or corrosion on the terminals. The terminals must be
clean and free of any foreign material which could impede
proper terminal contact.
However, cleaning the terminal with a sand paper or the like
is prohibited.
• Damaged connector body, exposing the terminals to mois-
ture and dirt, as well as not maintaining proper terminal ori-
entation with the component or mating connector.
• Improperly formed or damaged terminals.
Check each connector terminal in problem circuits carefully
to ensure good contact tension by using the corresponding
mating terminal included in the connector test adapter kit
(special tool).
If contact tension is not enough, reform it to increase contact
tension or replace.

• Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor con-
nection by shaking it by hand lightly. If any abnormal condi-
tion is found, change the wire harness assembly or
component parts with new ones.
• Wire insulation which is rubbed through, causing an intermit-
tent short as the bare area touches other wiring or parts of
the vehicle.
• Wire broken inside the insulation. This condition could cause
a continuity check to show a good circuit, but if only 1 or 2
strands of a multi-strand-type wire are intact, resistance
could be far too high.
If any abnormality is found, repair or replace as a wire harness
assembly.
