Troubleshooter: Code Tips, Symptom Tips, Common Problems, Tests and Procedures, Fast-Track Fixes



Welcome to Snap-on Training Solutions. This module is designed to help you get the most out of your MODIS Edge diagnostic tool, and covers the use of the Fast-Track Troubleshooter expert information.

The Snap-on Fast-Track® Troubleshooter contains experience-based tips designed to show the likely diagnosis for a specific vehicle, and to save repair time. Troubleshooter tips are based on real-world experience of OEM’s and specialty technicians.

20-30 Microprocessors
Interdependent Systems

According to the Society of Automotive Engineers, the average vehicle has 20-30 micro-processors. 

Each one monitors one or more interdependent systems and subsystems. A problem in one system, can show up as a symptom in another system.

Code Tips

System Selection, Engine highlighted

To get started, select Troubleshooter from the main scanner menu. And select the vehicle system you want to diagnose.

There are several tools within Troubleshooter to choose from. Let’s explore Code Tips. These take you down a step-by-step path, to determine the most likely components or circuits at the root of the problem.

Let’s drill down to a specific Diagnostic Trouble Code or DTC, also known as fault codes. In this case we will diagnose a code P0103. Select P0XXX for powertrain codes.

And select P01XX Fuel and Air Metering.

And there is our code P0103. Only tips related to the specific vehicle being tested are shown, to quickly lead you to the root cause of the problem.

Select the code to see the reason the code is set and a brief test to isolate, test and confirm the suspected cause of the fault. The repair tip highlights known issues for this specific vehicle and code to make it easier to diagnose. Code Tips are designed to show the most common faults first, saving you time and frustration.

Symptom Tips

Some problems don’t set a fault code. These can be particularly difficult to diagnose. The Symptom Tips in Troubleshooter can solve these problems, with step-by-step guidance to diagnose problems with no code. Select Symptom Tips.

Symptom Tips also contain information on thousands of known service issues. Here we see choices for several common problems. Let’s select Driving Problems.

What do we do when we have a lack of power?  Let’s select this item on the menu and find out.

Here we see the diagnostic power of Troubleshooter, a database of experience based information developed by master technicians. A common drivability problem for this specific vehicle is a loose crank sensor reluctor on the crankshaft.

Troubleshooter shows us a simple test to verify this problem.

Time Savers

Let’s look at one of the newer features in Troubleshooter – Time Savers.

You may need to know the firing order or the cylinder layout.

Troubleshooter tells us the firing order for each engine size and the cylinder layout.

Tests & Procedures

The Tests and Procedures section provides many ways to save diagnosis and repair time.

The After Repair section shows methods to verify that your completed repair has completely solved the customer’s problem. Such as relearn procedures and functional tests needed to verify and complete the repair.

Select General Information and you will find definitions for thousands of OEM terms and abbreviations, always at your fingertips.

Tests & Procedures covers thousands of simple tests to be certain a component is failed before you spend time replacing it. For example, this EVAP system test shows how to test purge and vent solenoids using your scanner.

Drive Cycle procedures show the fastest way to set readiness monitors needed to complete emissions work.

Fast-Track Fixes

Fast-Track Fixes cover common problems for the vehicle you are working on. These are proven fixes that have worked for technicians. Here we see a common fix for a P0446 code resulting from a plugged vent valve. Answers are shown in a straightforward Complaint, Cause, Correction format.
