Scan Tool Companion Car Diagnostic Training Software
A Quick Reference Guide to Onboard Diagnostics II for use with ANY scan tool or scanner software
Last Updated July 2015
If you have a scan tool or scanner software, you need this diagnostic guide!
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, Trouble Codes, and drivability, emissions,
and performance problems on 1996 and newer OBD2 vehicles with a scan tool.
This software does NOT interface with your vehicle. Rather, you use it with your scan tool or scanner software to better understand and use the information your scan tool is showing you. Scan tools read codes and display all kinds of data. But they do not tell you what to do with that information. That's where this product helps. If you have a code or a symptom, Scan Tool Companion can help you figure out what the problem is, what might be causing it and what other diagnostic tests or checks might be needed to nail down the problem.
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 to replace. The code only tells you the engine has a lean fuel problem. So you open the Scan Tool Companion program on your PC or laptop, click on the button for the code(s) you found, and Scan Tool Companion gives you a list of POSSIBLE CAUSES, and tells you WHAT TO CHECK and HOW TO CHECK IT. Is that cool or what? This is the kind of information that can help you fix your problem correctly the first time without having to blindly replace a bunch of parts and hope that one of them fixes the fault.
* 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 with 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 parts unnecessarily!
* Help Sections help you better understand the basics of your vehicle's onboard diagnostic
system (OBD II), including what it does, how it monitors various sensors and systems, and why it sets fault codes.
* Tips on how to pass an OBD II "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.
* A quick reference list of common generic "P0" fault codes .
Please note this program does NOT include "P1" manufacturer specific enhanced codes.
Most scan tools will give you a code definition for P1 codes if its data base includes your vehicle.
