HOW TO COPE WITH INTERMITTENT
MALFUNCTIONS
M1001013900451
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 like, what it sounds like, etc. Then ask about
driving conditions, weather, frequency of occurrence, and so
on.
.
2. DETERMINE THE CONDITIONS FROM THE
CUSTOMER'S RESPONSES
Typically, almost all intermittent malfunctions occur from condi-
tions like vibration, temperature and/or moisture change, poor
connections. From the customer's responses, it should be rea-
soned which condition is most likely.
.
3. USE SIMULATION TEST
Use the simulation tests below to attempt to duplicate the cus-
tomer's complaint. Determine the most likely circuit(s) and per-
form the simulation tests on the connectors and parts of that
circuit(s). Be sure to use the inspection procedures provided for
diagnostic trouble codes and trouble symptoms.
For temperature and/or moisture condition related intermittent
malfunctions, try to change the conditions of the suspected cir-
cuit components, then use the simulation tests below.
