Are you fully aware of and utilizing the capabilities of your scanning tools? BI-Directional Scan Tool has a huge impact on the precision and accuracy of work at home or in a professional garage, one of the great features of the Enhanced Scan Tool is bidirectional control, not just retrieving fault codes and viewing parameter data.
Bidirectional control is a general term used to describe sending and receiving information between one device and another. The vehicle engineers responsible for designing the computer control system programmed it so that the scanning tool could request information or command the modules to perform specific tests and functions.
Some manufacturers refer to bidirectional control as active testing, actuator testing, inspection testing, system testing, etc. Reinitialization and reprogramming can also be included in the bidirectional control list.
It follows that the scanning tool is also a two-way tool, which can be used to send information to the vehicle control module and receive information from the vehicle control module. Most enhanced scan tools are also capable of driving relays, injectors and coils, performing system tests, and more.
Most of Autel's davanced scanners are bi-directional, which include:
It can be seen from the above that Autel bi-directional scanning tools or active test scanning tools are basically tablet tools, and bi-directional/active test functions are almost invisible in handheld products.
In a recent high-profile case, Nissan has recalled over 440,000 vehicles due to a potential engine bearing defect that could lead to engine failure and increase the risk of a crash.
In this article, we’ll explain what engine bearings are, why they’re important, common causes of bearing failure, how to identify early warning signs, and whether diagnostic tools like OBD2 scanners can help.
Every car diagnostic process should begin with a VIN check, because the VIN lays the foundation for what your Autel OBD II scanner will detect.But here’s what it doesn’t tell you:Your car’s current condition. That’s where a car diagnostic tool like the Autel MD906Pro comes in.
How does the new Autel MD909 Pro stack up against other scanners in the MaxiDiag series? What upgrades does it bring, what are its standout features, and how does it compare to larger tablet-style diagnostic tools? And of course—how much does it cost? Let’s break it all down.
