Recently, we have been discussing car starting problems and the maintenance of batteries and charging systems. But how do you determine the root cause of a problem when it comes to a car breakdown? How do you know if your maintenance plan is working? You need an automotive diagnostic tool, such as a digital multimeter (DMM) or an OBD2 scanner. When used in conjunction with a vehicle service manual, a digital multimeter and OBD2 scanner can provide you with more in-depth information about the operation of your vehicle and can help you diagnose faults and confirm repairs.
Choosing the right code scanner can be a challenge, but once you have identified your specific needs, the task becomes easier. There are several grades and types of scanners available, which vary in price and functionality. Remember that a professional scan tool can be used for more than just reading diagnostic trouble codes (DTCs). When selecting a scanning tool, keep the following points in mind.
Connectivity - OBD2 scanners may be stand-alone or may require a cable adapter or Bluetooth adapter. Stand-alone code readers and scanners do not require any additional equipment. Simply plug them in and they will light up. To use a tablet or laptop as an OBD2 scanner, install the necessary software and connect the device to the car using a cable adapter, or connect wirelessly using a Bluetooth adapter.
Features - The most basic scanners can only read DTC's. You may need to look up the codes online or find diagnostic procedures in the service manual. Advanced scanners and adapters have a code description database that clears codes and displays vehicle data such as engine speed or sensor voltage. Specialist scanners have additional features such as freeze-frame data, graphically driven data and more.
Once you have a clear idea of what you need, it becomes very easy to pick the right one. After all, ancel v6 Plus+ are now available for basically every car on the market, so once you have purchased one, you can use it for other cars in the future. Spending less time and money to solve more car problems, OBD2 scanners are a must for car owners.
