Inspection of Intermittent and Poor
Connections
S6RW0D8204047
Most intermittents are caused by faulty electrical
connections or wiring. When a check for proper
connection is requested in a diagnostic flow, perform
careful check of suspect circuits.
If any abnormality is found, repair or replace as a wire
harness assembly.
• 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
moisture and dirt, as well as not maintaining proper
terminal orientation with the component or mating
connector. 4Contact coil circuit (horn, audio control and cruise
control switch circuit) check (cruise control model)
1) Check for continuity between each terminal of horn
switch terminals, audio control switch terminals and
cruise control switch terminals as shown in figure.
Is each measured resistance 3
Ω or less?Go to Step 5. Replace contact coil.
5Contact coil circuit check
1) Measure resistance between each terminal and other
terminal.
Is each measured resistance infinity?Contact coil and its
circuit are good
condition.Replace contact coil. Step Action Yes No

• 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 the terminal to
increase contact tension or replace it.
Special tool
(A): 09932–76010 Connector test adapter kit
• Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor
connection by shaking it by hand lightly. If any
abnormal condition is found, change the wire harness
assembly or component parts with new ones.
• Wire insulation which is rubbed through, causing an
intermittent 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.

Deployed Air Bag (Inflator) Module and
Activated Seat Belt Pretensioner Disposal
S6RW0D8206019
WARNING!
Failure to follow proper air bag (inflator)
module and seat belt pretensioner disposal
procedures can result in air bag deployment
and pretensioner activation which may cause
personal injury. The undeployed air bag
(inflator) module and the inactivated seat belt
pretensioner must not be disposed of
through normal refuse channels.
The undeployed air bag (inflator) module and
the inactivated seat belt pretensioner
contains substances that can cause severe
illness or personal injury if the sealed
container is damaged during disposal.
Deployed air bag (inflator) module and the activated seat
belt pretensioner can be disposed of through normal
refuse channels just like any other parts. For their
disposal, however, the following points should be noted.
• The air bag (inflator) module and the seat belt
pretensioner immediately after deployment / activation
is very hot. Wait for 30 minutes to cool it off before
handling it.
• Never apply water, oil, etc. to deployed air bag
(inflator) module and the activated seat belt
pretensioner to cool it off and be careful so that water,
oil etc. does not get on the deployed air bag (inflator)
module and the activated seat belt pretensioner.
• After the air bag (inflator) module has been deployed,
the surface of the air bag may contain a powdery
residue. This powder consists primarily of cornstarch
(used to lubricate the bag as it inflates) and by-
products of the chemical reaction. As with many
service procedures, you should wear gloves and
safety glasses.
• When disposing of the deployed air bag (inflator)
module and the activated seat belt pretensioner, be
sure to seal it in a vinyl bag.
• When air bag (inflator) module and seat belt
pretensioner have been deployed / activated inside
the vehicle which is going to be scrapped, leave them
as installed to the vehicle.
• Be sure to wash your hands with mild soap and water
after handling them.
