NO-1 >> No request for I/M examination from the custom
er: Before returning the vehicle to the customer,
always erase unnecessary DTC in ECM and TCM (Transmission Control Module). Refer to EC-
29, "Description".
NO-2 >> I/M examination, request ed from the customer: GO TO 13.
13.PREPARE FOR I/M EXAMINATION
1. Set SRT codes. Refer to EC-29, "

Diagnostic Work SheetINFOID:0000000005929745
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 MIL 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.
