Welcome to Snap-on Training Solutions. This module is designed to help you get the most out of your SOLUS Edge diagnostic tool, and covers the use of scanner functional tests.

Scanner Main Menu (Engine) 1 – Functional Tests highlighted

Functional Tests are a great way to isolate the cause of a problem between the controller, a component, wiring or other issues.  Functional Tests let you override the vehicle controller to take control of a system and determine if the vehicle responds properly or not.

Scanner Main Menu (Engine) 2 – Troubleshooter highlighted

Functional Tests are a powerful companion to Troubleshooter which often refers you to perform a Functional Test to verify a suspected issue.

System List – Engine

Tests and Procedures

As an example, we will use the injector balance test. Let’s begin by reviewing the description of this test. From the main scanner menu, select Troubleshooter, Engine and Tests & Procedures.

Functional Test Descriptions

Functional Test List 1

Functional Test List 2

Select Functional Test Descriptions to see a list of all available Functional Tests. Select Injector Balance to see a description of what the test will do for us.

Injector Test Description

Troubleshooter tells us how to perform and interpret the test. Now that we know what to expect, select the Back button to return to the Main Menu to perform the test.

Scanner Main Menu (Engine) 1 – Functional Tests highlighted

From Main Menu select Functional Tests

Functional Test Menu 2 – Injector Balance highlighted

Select the Injector Balance test

Injector Balance Test 1

Infector Balance Test 2

The next screens give us step-by-step test instructions. Select Continue.

Injector List

Select each injector one at a time to disable it and compare the RPM drop between injectors. 

If you are using a fuel pressure gauge in conjunction with the test, compare pressure drop between cylinders. 

Injector List

Select an injector once to deactivate and again to activate. This is known as a Toggle Test.

Functional Test Menu 2 – Output Controls highlighted

Output Controls
Actuator Tests

Other useful types of functional tests are Actuator Tests which check operation of devices like solenoid valves, motors and relays. And Output Controls, which monitor live output data from the vehicle while you activate vehicle components.

Select Test screen - AC Relay Graphs (On/Off) highlighted

A good example of a powerful Output Control is the AC Relay Test.

AC Relay (On/Off) Graphs 

Select the test and the AC Relay control shows at the top of the screen, and the live data parameter view opens.

AC Relay Graphs (On/Off) drop-down menu

By using the Functional Test and selecting ON, you are overriding the controller. If you command the relay to turn ON and it does not activate you’ve just eliminated the controller from the possible causes. This pinpoints the likely problem to be the relay or wiring. In order to choose relevant data parameters to monitor, use the Back button to open the Data Manu.

Custom Data List

Data Menu – Acc/Electrical/Theft Data highlighted

Acc/Electrical/Theft Data graphs

Select the data group Accessory, Electrical, Theft Data.

Click on the checkmark icon.

Custom Data List Menu 1 (checked)

Customer Data List Menu 2 (unchecked)

Let’s view the data parameters relevant to the AC Relay Test. First use the Select All icon to deselect all parameters.

Custom Data List menu 2 (some checked)

Select just the parameters you want for your diagnosis. To perform the AC Relay test we will select AC-related data. 

AC Data Graph

This will speed the data refresh rate to help you catch short intermittent glitches. Here's your Custom Data list. Now you can observe the vehicle data response when you command the AC Relay On and Off.
