How to Use Bi-Directional Scan Tool

    How to Use Bi Directional Scan Tool

    Vehicle scanners have improved since they were first introduced, as manufacturers add new features. In addition, as technology has developed, various scanners have emerged, including bidirectional obd2 scanners for auto repair businesses and technicians.

    An advanced tool with more intricate functionality than a normal scanner is a bi-directional scanner. Bi-directional scanners transmit commands to the vehicle in addition to pulling data from it, in contrast to normal scanners that simply reveal the status of the various sub-systems of the vehicle.

    However, running a bidirectional scanner can be a bit challenging due to its many complex features. Using Ancel X7 as our example study, this article will discuss how OBD2 Scanner uses them.

    A Bi-Directional Scanner's definition

    A bi-directional scanner offers a more thorough and sophisticated option than the majority of typical scan instruments. It combines the benefits of a basic and sophisticated scan tool and goes one step further by enabling commands to be sent to the car's onboard computer. Any computer-controlled component can be activated with a bi-directional scanner.

    You won't have to randomly swap out parts when diagnosing autos thanks to this distinctive feature. Instead, you can instruct the ECU to activate motors, switches, and sensors in order to find the problematic component.

    For instance, a malfunctioning switch or motor come to mind as the cause of a car window that won't roll down. However, you can speed up this process by instructing the ECU to roll up the window using a bi-directional scanner. If the window moves in response to the order, the motor is still functional and just a new switch is required.

    However, you should conduct your own independent investigation to confirm the offered features before moving through with the purchase of one of these scanners. In order to avoid receiving a product that cannot support your car.

    We'll review the Ancel X7 bi-directional to provide a clearer explanation of the features of bi-directional scanners and how to use them.

    Ancel X7 Bi-Directional Scanner Operation Guide

    If you have the necessary information and a user manual, operating the Ancel X7 scanner is simple. To grasp any of the scanner features, you will require some mechanical expertise or a related talent. The procedure to turn on and connect the scanner to your car is detailed below.

    Configure the Scanner

    The scanner must initially be set up after being unboxed. Launch the Ancel X7 app while the device is connected to your wifi. Now signup for an account and activate it. A sheet of paper included in the package contains all the information you'll need. Select your favourite language and update the software while you're at it.

    The scanner should be connected to your car

    The gadget is ready to couple with your car once you've configured it and updated the software. To start the Bluetooth connection, receptacle the system VCI box into the OBD II port of your car. As soon as the VCI box is plugged into the OBD II port, the power indicator should flash red. Next, connect the tablet's Bluetooth to the system.

    Examining the Car

    Diagnose, Hot Function, Upgrade, Data Manager, Quick Support, DTC Query, Feedback, Data Playback, and more choices may be found on the Ancel X7 app. To run a diagnostic check, choose the Diagnose option.

    Once you click the "Diagnose" icon, you can either manually enter the vehicle's make and model or let the gadget do so for you. Wait until the scan is finished if you selected auto-detect; your precise vehicle make and model will then appear. After choosing your vehicle's make and model, you'll be given a few alternatives, such as "System Selection," "Quick Test," or "Hot Function."

    Short Test

    All of the car systems are scanned using the 'Quick Test' option. from the drivetrain to the transmission, the tire pressure monitoring system, the HVAC system, the SRS module, the body control module, and every other system in the car.

    The scanner displays the results after it has finished the test. Systems that are trouble-free will have a green 'OK' inscribed in front of them. The number of issues discovered is written in parentheses in front of the red "DTC" next to the systems that have problems. You can scan the problematic system again, and the scanner will retrieve its error codes.

    Warm Function

    All of the vehicle's features are listed on the screen that opens when you select the 'Hot Function' option. Key programming, gear learning, bleeding of the ABS, DPF, etc. Even if all these features are present on the scanner, that doesn't necessarily mean your car can use them.

    System Choice

    All of the vehicle modules are listed when the 'System Selection' option is clicked. By selecting a specific module, you can look into it more. You can read 'Live Data' and observe the sensor system's activity on a real-time graph.

    Final Reflections

    The capacity to send commands to the onboard computer is a bi-directional scan tool's main advantage over a basic or advanced scan tool. But because they typically need subscriptions to acquire the most recent software update, these types of scanners are best suited for professional mechanics.

    Ancel's X7 scanner is a dependable choice that you have to take into account. The X7 is overkill if you're a casual driver or do-it-yourselfer looking to get a car scanner. Instead, you should think about the BD500, VD500, or AD310 scanners from Ancel.
