Figure 6-49 Functional test example
A Test icon on the toolbar activates the test, and a Return, or similarly named, icon
cancels the test. For variable control tests, the variable value displays between the
main body and the toolbar. Plus and Minus icons on the toolbar increase and
decrease the variable value.
A Data List icon, shown to the left, is available on the toolbar for some tests.
This feature allows you to change which data list displays in the main body
without exiting the functional test. The icon is only available when the test
is inactive.
6.6 Troubleshooter
Troubleshooter appears in a Scanner Main Menu only if tips are available for
the system selected on the identified vehicle.
Troubleshooter is a database of experience-based repair strategies and information,
that has been compiled and validated by experienced technicians. Troubleshooter
simplifies the diagnosis process, as it contains information on virtually all common
diagnostic trouble code (DTC) problems and driveability symptoms.
Troubleshooter information is organized into a series of diagnostic tips that are
designed to quickly lead you to the root cause of a particular problem. The tips are
vehicle-specific, which means only tips that relate to the identified vehicle are
presented. Selecting opens a menu that may include:
• Code Tips—provides detailed information on setting conditions, testing, and
interpreting test results for specific codes (Figure 6-50 and Figure 6-51).
• Symptom Tips—provides diagnostic tests and procedures based on vehicle
operation.
• Time Savers—provides supplemental information, such as firing order and #1
cylinder location, that may be needed to make a diagnosis.
• Common Problems—provides advice and remedies for certain “pattern
failures” that have been experienced on vehicles of the same model.
• Tests and Procedures—explains how to perform certain tests on the specific
test vehicle. Some tips provide specifications and installation information as
well.
• Data Scan—contains information and guidelines on how to validate data
readings for certain sensors and actuators, PID data values are provided.
