Diagnostic Work Sheet
INFOID:0000000012197714
DESCRIPTION
There are many operating conditions that lead to the malfunction of
engine components. A good grasp of such conditions can make trou-
bleshooting faster and more accurate.
In general, each customer feels differently about symptoms. It is
important to fully understand the symptoms or conditions for a cus-
tomer complaint.
Utilize a diagnostic worksheet like the WORKSHEET SAMPLE
below in order to organize all the information for troubleshooting.
Some conditions may cause the MIL to illuminate or blink, and DTC
to be detected. Examples:
• Vehicle ran out of fuel, which caused the engine to misfire.
• Fuel filler cap was left off or incorrectly screwed on, allowing fuel to
evaporate into the atmosphere.
