OBD2 diagnostics tools are quite handy when it comes to scanning a car for problems. However, not all OBD2 scanners offer advanced functionalities; only a few do, and ANCEL FX4000 is one of them.

ANCEL FX4000 is an ideal choice for mechanics. It lets you diagnose complex problems such as faults in the brake system, ABS issues, oil service light problems, battery controls, etc.

It can also handle small issues. Its versatility is a good reason to go for it. If you’re a professional, you will have to deal with different makes.

You can’t get a scanner for each model, which is why ANCEL FX4000 can be a good choice. It’s compatible with European cars (2001 – 2016), Asian vehicles (2003 – 2016), and American cars (1996 – 2016).

ANCEL FX4000 is tailor-made for mechanics. If you use a few features extensively, you can turn to the FN hotkey, which acts as a speed dial. It lets you customize the main menu with the functions that are mostly used. This feature can help save time and solve issues quickly. You will not have to scan through the functions to find what you need.
