VIDEO TRANSCRIPTION

Welcome to Snap-on Training Solutions. This module is designed to help you get the most out of your ETHOS Edge diagnostic tool, and covers the use of Global OBD-II scanner functions.

Standard emissions-related coverage
All 1996-newer vehicles

Global OBD-II scanner coverage is strictly related to emissions-related coverage and is universal in that all vehicles sold in the US and Canada since 1996 must comply with this standard. 

ETHOS Edge Home Screen

All ten modes of OBD-II are covered by this tool and are accessed by selecting the OBD-II icon on the home screen. All service modes are not supported by all vehicles, so the available menu selections will vary. Note: some vehicles do not support all ten modes, so results will vary.

OBD Direct

OBD Diagnose and Training Mode

Let’s start by exploring the OBD Direct functions. This opens a menu of two choices: OBD Diagnose and OBD Training Mode.

Training mode allows you to navigate through the menus, and see results, without being connected to a vehicle. This is a good way to explore OBD-II capabilities. For this demonstration, we will select OBD Diagnose to diagnose a vehicle.

Main Menu OBD

Let’s select Connector Information to see where to find the data link connector or DLC on the vehicle.

Manufacturer List

Let’s choose an Alfa Romeo. Some of these models may not be familiar in the US, but all vehicles are included in Global OBD-II.

Model List

So you always know you have emissions coverage on any vehicle. Let’s select model 147.

Alfa Romeo Connector

Here’s the connector location. Have you ever searched for a connector that was not in the “usual place?” The Data Link Connector locator makes it easy. Now select Continue.

Select Service List 1

Readiness Monitors

Coverage includes all ten modes of OBD-II and readiness monitors, which are very important when verifying emission repairs. Readiness monitors provide a status report on emissions-related systems. Some monitor reports require an extensive drive cycle in order to complete the requirements of the test.

Monitors – ($04) Clear Emissions Related Data highlighted

Results are shown for each monitor, whether the monitor is supported by the vehicle, and whether the drive cycle test is complete for each monitor. Critical monitor tests must be complete in order for the vehicle to be ready for an emission test.

Ten Modes of Global OBD-II

Let’s take a brief look at the valuable information available in each of the ten modes of OBD-II. Mode 1 displays live data parameters for engine and emissions systems. This is typically your first step when diagnosing a check engine light.

Mode 2 Menu

Mode 2 Results

Mode 2 displays freeze frame data. This is a record of vehicle data parameters captured at the moment a fault code was set. This can give valuable insight into the operating conditions of the vehicle at the time of the fault.

Mode 3 Menu

Mode 3 Results

Mode 3 displays the OBD-II trouble codes currently set by the vehicle. OBD-II fault codes are standard for every vehicle manufacturer. The code definition is also shown on the right to explain the meaning of the code. 

Mode 4 Menu

Mode 4 Results

Mode 4 provides an easy method to turn off the malfunction indicator lamp after a repair. Caution. This also clears freeze frame data, pending codes, and readiness monitors. So this should usually be the last step in your repair process.

Mode 5, 6 & 7 Menu

Mode 5 Results

Mode 6 Results

Mode 7 Results

Modes 5, 6 and 7 display data parameters related to oxygen sensors, saved results of manufacturer-specific tests, and trouble codes detected during the last drive cycle. This is useful in determining the root cause of recurring fault codes.

Mode 8 Menu

Mode 8 Results

Mode 8 allows a service technician to invoke an on-board test to seal the evaporative system for a pressure test. This function varies by manufacturer. For example, on Ford systems, this closes the canister vent solenoid for ten minutes.

Mode 9 Read Vehicle Identification Menu

Mode 9 Results

Mode 9 can read the vehicle identification number or VIN, as well as the calibration and ID numbers for the engine control unit or ECU.

Mode 9 In-Use Performance Menu

Mode 9 Results

Mode 9 Performance Tracking displays a record of the number of times each of the readiness monitors have been completed.

Mode 9 Menu

Mode 10 displays diagnostic trouble codes with permanent status. These codes are stored in the powertrain control module for 400 days and cannot be cleared. 

Remember for easy navigation you can use the back icon at any time to step back one screen, and the home icon as a shortcut to the main menu.
