Prepare You the Emission Test

When your check engine light shows up again, you don’t need to be panic and take another costly trip to mechanics. Running diagnostics is easy with this obd2 scan tool. It will quickly test every emission-related module status via reading/clearing codes and viewing live data. You can turn off the error light, and identify issues with the emission system before the inspection.

Saves You Time & Money

TOPDON’s AL400 helps you save hundreds of dollars from unnecessary repairs and spare you from avoidable trips to automotive shops. This scan tool gives the same essential information you’d get at the dealer, and there’s no labor cost. Even if you don’t want to perform the repairs, use the ArtiLink 400 to arm yourself with knowledge of potential problems and demand exactly what you need.

Helps Troubleshoot Tricky Issues

This diagnostic tool gives you a window into what may be wrong with your car when the check engine light shows up. It can effectively read and clear the check engine light, as well as retrieve codes to tell you the exact nature of an emission-related issue. You may find a misfiring engine or a loose gas cap before they’re a real problem.

  3-Color LED Indicators

This diagnostic OBD2 code reader also has an “ideal early warning system” to help you find possible dangers before they occur, with red, yellow, and green LED lights to indicate the health status at a glance. The RED light alerts you when fault codes are found; the YELLOW light comes up when there is pending code; the GREEN light shows up when there are no fault codes.

Graphic Data Stream

Another highlight of this scan tool is the real-time error detection, which is presented in graphics and can be merged for easy and intuitive car diagnosis. You’ll be quickly notified of a problem as soon as it appears to help you pinpoint any underlying issues and get your vehicle back on the road in no time.

DTC LookUP Library

Better yet, the diagnostic tool will define the retrieved code for better interpretation and analysis.  This is because TOPDON AL400 has a built-in DTC lookup library. When you don’t understand the code, just go through its DTC lookup. You don't have to get the code and then Google the code online to see what it means.

2.4" TFT Color Screen

This obd2 scanner is simple to use as it comes with a 2.4” color display being bright and sharp enough to see in any light condition. The icons are clear and the menu is easy to operate. Navigating is never an issue and is easy for even beginners to grasp. All you need to do is plug it into the OBD2 port, welcoming you with a bright and nicely pixelated screen.

Lifetime FREE Update

AL400 is regularly updated, for always running smoothly and adding more vehicles to the compatibility list. Unlike other automotive scan tools which may require subscription fees, renewing them is costly, while this diagnostic tool can be fully updated all through its lifetime with NO extra costs.
