Best OBD II Scanner Reviews: It is distinctly evident from the past that there exists a boundless scope for advancement and growth in the technological aspects of a vehicle to enhance its productivity and efficiency by monumental proportions. To facilitate these advancements, highly detailed reports of the vehicle’s previously recorded operations are required.

On-Board Diagnostics II (OBD-II) is the standardized system which the onboard computers in vehicles, like cars and trucks, use for formulating reports and self-diagnostics. An enhanced version of the older OBD in terms of both standard and capability, the OBD-II scanner is subdivided into 2 categories of models- Code Readers, which are comparatively inexpensive, and, Scan tools, which are comparatively expensive and consist of a wide variety of features.

What is an OBD-II Scanner?

The OBD-II scanner is a device which provides the user with a vehicle’s reported self-diagnostics. However, the mechanism of an OBD-II depends on whether it is a basic code reader device which provides the limited feature of simply reading and clearing codes, or an advanced scan tools reader which enables the user to access the manufacturer-specific codes, live and recorded data, and advanced troubleshooting details.

The standardized OBD-II scanners are relatively simpler to use as they all have a universally same connector. Basic scan tools function with ease as they can be conveniently inserted into the OBD-II diagnostic connector of the vehicle. The OBD-II scanner is only functional with vehicles manufactured post the year 1996.

OBD-II Scanner Frequently Asked Questions (FAQs)

How does the OBD-II Scanner work?

The device continually stores the information and data about the vehicle’s process in its database to provide with self-diagnostic reports. The device switches the “Check Engine” or the “Service Engine Soon” light on whenever a problem is detected.

How sophisticated is the OBD-II system?

The OBD-II system has an exquisite mechanism design which detects serious problems with the vehicle and displays alerts even before the driver becomes aware of the problem. This saves the driver huge service and repair costs.

What does the “Not Ready” signal mean?

The servicing technician, when finished with the components’ repair procedure, turns off the “Service Engine Soon” light to “Not Ready”. The device will stay on “Not Ready” till the computer has had adequate time and data to report the vehicle’s performance. And if the vehicle’s emission system reads “Not Ready” for the initial testing stage, a tailpipes emission test will have to be conducted.

What is the difference between OBD-II Scans and Treadmill Tests?

The treadmill test measures the concentration gases coming out of the exhaust pipe of a vehicle, whereas, an OBD-II scan is an automotive test done by an electronic hand-held device plugged into the vehicle’s diagnostic connector port.

What are the causes for failing an OBD-II test?

Faulty gas cap, malfunctioning catalytic converter, incorrect ignition timing, misrouted vacuum lines, faulty positive crankcase ventilation (PCV) system or exhaust gas re-circulation (EGR) system, contaminated engine oil, malfunctioning air injection system, and fuel system malfunctions are the reasons for failing an OBD-II scanner test.

The OBD-II scanner is an exceptionally well-designed tool to enable a vehicle owner to save huge costs on maintenance and repairs. If you are interested in DIY diagnostic procedures for your vehicle, then this scanner is strongly recommended for a purchase.
