NTC-1A No Trouble Code Menu - Start Here

No Trouble Code Test Menu:

The "No Trouble Code" testing is broken down into three sections:

1. No Code Complete Test -- see figure

2. No Code Quick Individual Test
If you suspected 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.

Flow Chart:

3. No 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 DTC Test and appropriate other information has been reviewed before attempting to diagnose a symptom.

Select the symptom that most accurately describes the vehicle's driveability problem and them perform the test routine that pertains to this symptom. Perform each routine test in sequence until the problem is found.
