Scan Tool Companion is a quick reference guide for ALL scan tool users.

This program provides guidance and help on how to troubleshoot Check Engine Light problems, driveability problems, emissions problems,
and performance problems on ANY late model vehicle with OBD2 using a scan tool.  Helps you get the most out of your scan tool.

This software does NOT interface with a vehicle. It is designed to help YOU make sense out of what your scan tool is telling you.  Scan tools read codes and display data.  But they do not tell you what to do with the information.  That's where this product helps.  If you have a code or a symptom, it tells you what might be causing it and what components to check.

For example, say your Check Engine light is on and you have a P0171 or P0174 lean code.  Now what do you do?  The code does not tell you what to check or what component to replace.  It only tells you the engine has a lean fuel condition.  Scan Tool Companion gives you a list of POSSIBLE CAUSES, and tells you WHAT TO CHECK and HOW TO CHECK IT.  This is the kind of information that can help you fix your problem correctly the first time.


FEATURES include:

* Diagnose problems by Symptom, By Code or by System.

Scan Tool Companion tells you the most likely causes of symptoms or codes, tells you what to check, and
what PIDS (data parameters) you need to look at with your scan tool to identify the fault.
It also offers expert tips on what parts might need to be replaced and why.
It's like having an expert technician at your fingertips to help you make your diagnosis.

This kind of guided diagnostics is only available in the most expensive professional grade scan tools.

There is even information on Mode 06 diagnostics, what it is, how to access it and how to use it.

* Saves you time, frustration and replacing the wrong parts!

* The program also contains sections to help you better understand the basics of your vehicle's onboard diagnostic system (OBD2), including what it does, how it monitors various sensors and systems, and why it sets fault codes.

* A handy OBD2 fault code look-up page that allows you to look up generic DTC codes by number or type of fault ("generic" OBD2 codes only that are common to all OBD2 compliant vehicles).

* Tips on how to pass an OBD2 "plug-in" emission test (what's required, what they look at, what to do if your vehicle is rejected or fails).

* Quick reference sections on basic sensor operation, fuel injection, ignition and emissions.

NOTE: This software does NOT interface with your vehicle or make your PC function as a scan tool.
It is designed to help you make better use of ANY scan tool you already own so you can more accurately diagnose and repair faults that turn on your Check Engine light.
