2. NO TROUBLE CODE QUICK INDIVIDUAL TEST (individual test only)

If you suspect any of the above items to be the cause of the vehicle’s driveability problem, perform
the associated test(s) individually. Return to No Trouble Code Menu if driveability problem still
exists, or perform No Trouble Code Complete Test.

3. NO TROUBLE CODE QUICK SYMPTOM TEST (symptom test only)

Symptom checks cannot be used properly unless the driveability problem characteristic actually
happens while the vehicle is being tested. To reduce diagnostic time, ensure that the DTC-TEST and
appropriate GENERAL INFORMATION sections have been reviewed before attempting to diagnose
a symptom.

Select the symptom that most accurately describes the vehicle’s driveability problem and then
perform the test routine that pertains to this symptom. Perform each routine test in sequence until
the problem is found. For definitions, see Section 12.0 in GENERAL INFORMATION section in this
manual.
