HOW TO COPE WITH INTERMITTENT
Most intermittent malfunctions occur under certain conditions. If those conditions can be identified, the
cause will be easier to find.
TO COPE WITH INTERMITTENT MALFUNCTION;1. Ask the customer about the malfunction
Ask what it feels
it sounds like, etc.
Then ask about
conditions; weather,
frequency of occurrence, and so on.
2.Determine the from the custom-
er’s responses
Typically, almost all intermittent malfunctions
occur from conditions like vibration, tempera-
ture and/or moisture change, poor connections.
From the customer’s replies, it should be rea-
soned which condition is influenced.
3. Use simulation test In the cases of vibration or poor connections,
use the simulation tests below to attempt to
duplicate the customer’s complaint. Determine
the most likely circuit(s) and perform
tion tests on the connectors and parts of that
circuit(s). Be sure to use the inspection proce-
dures provided for trouble codes
a n d t r o u b l e s y m p t o m s .
For temperature and/or moisture conditions re-
lated intermittent malfunctions, using common
sense, try to change the of
circuit components, then use
tion tests below,
4. Verify the intermittent malfunction is elimi-
nated
Repair the malfunctioning part and try to
the condition(s) again to verify the intermit-
tent malfunction has been eliminated.
SIMULATION TESTS
For these simulation tests, shake, then gently bend , pull,
and twist the wiring of each of these examples to d uplicate
the intermittent malfunction.
l Shake the connector up-and-down, and right-and-left .
