Exiting the Scanner
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 typically includes:
•
Code Tips
—provides detailed information on setting conditions, testing, and interpreting test
results for specific codes.
•
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.
•
Fast-Track Data Scan (Normal Values)
—contains information and guidelines on how to
quickly validate data readings for certain sensors and actuators, live data values are provided
for comparison.
Certain live data parameter values display directly within the tip when performing Troubleshooter
tests and procedures. A tip may also contain a hyperlink to a another test or procedure or a
supplemental operation, such as Clear Codes. Hyperlinks are shown in blue, and tapping them
opens the link.
5.4 Exiting the Scanner
The Scanner remains open as long as there is an active communication link with the vehicle. You
must interrupt this communication link in order to exit from Scanner tests and power down the
scan tool. A warning message displays if you attempt to shut down while the Scanner is
communicating with the vehicle.
NOTE:
i
Damage to the vehicle electronic control module (ECM) may occur if communication is disrupted.
Make sure the data cable is properly connected at all times during testing. Exit all tests before
disconnecting the test cable or powering down the tool.
