Welcome to Snap-on Training Solutions®. This module is designed to help you get the most out of your TRITON-D8® diagnostic tool, and covers the powerful information available in Guided Component Tests.

Snap-on’s exclusive Fast-Track® Guided Component Tests include a variety of resources to test automotive components for a confident diagnosis. This avoids replacing the wrong part and the risk of comebacks.

Guided Component Tests provide vehicle specific component test procedures and information that aid in scope and meter setup. Let’s select a vehicle and see what component tests are available.

Guided Component Tests

Select Guided Component Tests, select Chevrolet, pick the Model Year, 2014.

Let’s look at a Tahoe, select the engine, confirm the vehicle identification. Select OK.

Once a test vehicle is identified, you can select a variety of component tests. Scroll to desired system. For this Tahoe we have a choice of tests for the multiple systems. Let’s get some help with the Mass Airflow sensor. Select ENGINE.

Scroll down and select Mass Airflow Sensor and see the information resources available for the Mass Airflow Sensor, including component information and several tests procedures. Select Component Information.

Component Information

Vehicle-specific information is available at your fingertips for the exact component selected. We see an explanation of Chevrolet Mass Airflow Sensor operation, a connector pinout illustration, the best location to access a connector, a component locator, and timesaving Tech Notes explaining common failures, factory updates and recalls.

Use the scroll bar along the right edge of the screen to view additional information. You get a complete explanation of how the component normally operates and how to test it.

Select the back icon to return to the component menu.

Component Tests

The meter appears and is pre-configured for the Chevrolet Mass Airflow Sensor test. Select the screen expand icon to view full-screen instructions for performing the test. And there you have a guided procedure for the Signature Test. Plus connection tips and resources to reduce setup and testing time. And also a known good waveform so you know exactly what test results to look for. Select the expand icon again to see the meter on the full screen. Selecting the Cursor button on the toolbar places two vertical rules on the screen that can be repositioned to measure intervals.

To reposition the cursors, tap the Cursor icon, then touch and drag the numbered rectangle in the sweep area of the display to move that cursor to where you want it.

Select the profile icon at any time to see and change the meter configuration controls. These allow you manually control the meter settings. The Training Solutions modules on Meter and Scope cover all these controls in detail.

Scope Functions - 6 Million Data Samples per Second

At six million data samples per second, the Snap-on scope function can capture many more samples than displayed on most standard display screens. To take advantage of this capability select the peak detect function. The scope samples at the maximum rate possible and captures extremely fast peaks and glitches, like this ignition spike.

Coupling AC subtracts the average value of a signal so that small variations display prominently on the waveform. This blocks the DC portion of the signal to amplify the AC signal without driving the waveform off the screen. Simply touch the coupling AC icon to activate.

Scope Trigger

The Scope Trigger sets a threshold value that initiates the waveform display. When the voltage passes the threshold value, a new waveform begins. This produces a very stable waveform that does not flicker or drift. The trigger point appears as a plus sign on the display. Touch and drag the plus sign to position it.

Touch the trigger icon to trigger when the voltage rises to the threshold value. Touch the icon again to trigger when voltage falls to the threshold value.

Select the Plus icon to fine tune trigger position or touch the large plus sign on the control panel to use the four-way control for a more precise setting.

Easily change the time scale sweep by using the sweep menu. Touch the scale value to change it any time with this popup menu. After making a menu selection, simply touch a blank spot on the screen to hide the menu. Highlight and select 2 milliseconds. Changes in sweep "shift on the fly" so you can immediately see what your new selection will look like. Tap again to select a different sweep if desired.

Snap-on is dedicated to helping you get the most out of your diagnostic tool and keep your customers happy. Be sure to watch the rest of the modules in this Training Solutions series.
