Diagnostic Work Sheet
INFOID:0000000004779988
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 an incident. It is
important to fully understand the symptoms or conditions for a cus-
tomer complaint.
Utilize a diagnostic worksheet like the one on the WORKSHEET
SAMPLE in order to organize all the information for troubleshooting.
Some conditions may cause the MI L to come on steady 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.
