The engine, transmission, and/or interior features is frequently include in this information.

Modify certain settings

Many scanners can control some fundamental systems in the vehicle in addition to monitoring data. The cryptic Check Engine light, for example, can be reset with the push of a button for a variety of reasons. Advanced scanners can also manage built-in tire pressure monitors, temperature sensors, and a variety of other features.

Pricing of OBD2 scanners

$50 and under

These OBD-II scanners are basic versions with basic functions including trouble code detection. Some will convert codes into simple explanations, but the majority will simply display the code.


More modern OBD-II tools and auto-scanners, particularly wireless versions, are typical in this price range. Some of the higher-end models in this range also have additional features, such as live data monitoring.

$100 and above

The majority of professional scanners is found in this price range. At this level, you can expect a multitude of monitoring and control tools from the scanners. Unfortunately, with more extensive capabilities, the price tag can easily soar.

Setting Access of OBD2 scanners

A diagnostic scan tool can be extremely useful for fine-tuning and controlling specific vehicle parameters. To accomplish so, the scanner must be able to access multiple settings, track various statistics, and do more than just display fault codes. Warning lights and certain sensors should control by a high-quality code reader.

Connectivity of scanners

Most OBD-II scanners use a cable to connect to the vehicle’s OBD-II port. This has certain advantages because these scanners don’t require any battery power to function (they draw power straight from the battery). Wireless scanners with a separate socket and display unit/app allow you to work while keeping the scanner plugged in or moving about the vehicle.
