Many drivers find it hard to use the Blue driver bidirectional tool. If you’re one of them, I’ll show you how to use the blue driver OBD2.

If you want to scan something, this tool is one of the best on the market. It will let you run a test after you connect it to any smart device and turn it on. In the right place, it can send a signal to the device you’re using.

Blue driver comes with its own app that lets you put data from your car on your phone, even though many other scanners need a separate app to do this.

With this scanning tool, you’ll be able to move around the garage as you check and fix your car.

What is the difference between unidirectional and bidirectional scan

Regardless of what kind of repair you want to make to your car, you need to use the right tools. This includes a scanner that can help you figure out what’s wrong with your car. But first, you need to know the difference between one-way and two-way scans.

For the first thing, you need to know that OBD scanners are used to do all of the technical work on your car or truck. There are onboard computers in today’s cars that help you with different things. When you bring your car to a mechanic, the scanner will just be plugged into the computer and the computer will download all of the problems with your car. This is a big advantage. It can even show you problems that you haven’t yet found out about, so you can fix them.

In the market today, there are a lot of different types of scanners, but the most recent one is bidirectional. It doesn’t just get information from the scanner. It can also put in information.

This is how the unidirectional scan works: It measures between 0 and 1. In this case, its sensor moves only in one direction and doesn’t report any positive voltage or milliamp output at all. There are many large applications for the unidirectional scan. For example, it is used to check the static duct pressure. This means that the high port will be connected to the point in the duct that is being watched.

When you want to know if you need to change a filter, you can measure the difference in pressure in the filter to find out. In this case, you will connect the high port to the filter’s inlet. Then, you will connect the low port to the filter’s discharge side. But the bidirectional scan tells the car what to do.

The reason this is important is that you might want your car to do certain things before you can figure out what’s wrong with it. That means you don’t need to ask for help from another source or someone. You send a command to the car through a bidirectional scan.

Is Blue driver bidirectional scanner

It is true that Blue driver is a bidirectional scanner, and it is one of the best OBD2 scanners you will find on the market right now. I like that it works with both Android and iOS, which is a good thing.

It has a diagnostics reading that can show and save a lot of different reports. As a result, you can now watch in real-time how the transmission, engine and other parts are working together.

Can Blue Driver program key fob

Yes, the blue driver scanner can do a good job of programming key fobs for a wide range of cars, because it can even read the ECU. You should know that it’s not a dedicated key programmer, but rather a scanner that can make keys. The blue driver comes with a guide that even non-experts can use to make new keys for their cars.

Does the car have to be running to use an OBD2 SCANNER?

You need to know that the OBD2 scanner is a diagnostic tool that lets other electronics talk to your car’s computer system. So when your car’s sensors detect a problem, it sends out trouble codes, which show up on your dashboard in the form of a red light.

Not at all. You’ll need to turn on the engine and let it run for a while without running your car in order to use the OBD2 scanner. This is how it works: When you plug the OBD2 scanner into the OBD port, you should turn off your car first. Then, start your car and wait for the scanner to start up.

How to use a blue driver OBD2 scanner

This is how I’ll show you how to use the blue driver OBD2.

The first thing you need to do is download the Blue driver App from the Google Play Store.

Install is the next thing to do, so click on it.

Now, connect your Blue Driver.

Note that you can connect Blue Driver to your phone or tablet either through the app or through Bluetooth settings on your phone or tablet.

Step by step, follow these steps:

In the first place, you can only do the in-app pairing if there isn’t already a Blue Driver on your phone or app. You have to pair each BlueDrive one by one.

Now, start your car.

It’s then time to plug in the BlueDriver.

Then, wait for the blue light to go out.

Get the BlueDriver app up and running.

Tap Connect in the top or right corner of the app.

Now, click Allow to let Location Services turn on.

There is a button called Scan for BlueDriver Sensors that you need to press to look for them.

This is the time to pick your new BlueDriver, which you can see under Other Available BlueDriver Sensors.

In the event that you need to confirm a code or PIN, then tap Pair to do so. But if your phone needs a pin, then enter 0000 or 1234.

Once the app is paired by following these steps, there will be a connection.

In this case, the scanner is able to scan both ways

The bidirectional is a tool for diagnosing cars that lets mechanics tell a car what to do. So not only does it help you get information from the scanner, but it also makes it easier to find things in the scanner Unlike other scanners that are available, this one can only be used to read. A lot of things can be done with the bidirectional scanners when it comes to fixing cars.


We learned that the unidirectional scan can only measure between 0 and 1. Due to the sensor that comes with it, it can only move in one direction. It can’t report any positive voltage or milliamps. But bidirectional scanners can run system tests, change the ECU, and get into the engine control module. They are one of the best tools that any mechanic can have. Bidirectional scanners are one of the best things they can have.
