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.
Repair and Inspection Required after AccidentS6RW0D8204048
CAUTION!
• All air bag system components, including
the electrical harness (component
mounting points), must be inspected after
an accident. If any components are
damaged or bent, they must be replaced
even if air bag system activation did not
occur.
• Never use air bag system parts from
another vehicle.
• Do not attempt to service the parts below.
Service of these parts is by replacement
only.

WARNING!
To avoid deployment when troubleshooting
the air bag system, do not use electrical
equipment such as a battery powered or AC
powered voltmeter, ohmmeter, etc., or any
type of electrical equipment other than that
specified. Do not use a non-powered probe
type tester.
Instructions must be followed carefully,
otherwise personal injury may result.
You should be familiar with the tools listed under the
heading “Special Tool”. You should be able to measure
voltage and resistance. You should be familiar with
proper use of a scan tool such as Air Bag Driver /
Passenger Load Tool, Connector Test Adapter Kit and
the Digital Multimeter.
