You are definitely living on wheels if you possess a car and drive a light or medium truck or even an 18-wheeler to transport commodities from one state to another. The usage of the same code reader for cars and trucks is a common concern among truck owners.
For vehicles, certain code readers are designed, and for trucks, others. While they look great, do code readers that can read computers from cars and trucks really exist? If you could imagine a heavy duty truck scanner tool that could read everything, you'd learn about it in this post.
Can a single code reader read computerized trucks and cars?
The OBD2 Scanner is compatible with gasoline and diesel engines, so you only need one. The only difference is whether the engine is powered by a diesel or gasoline engine. All trucks run on diesel. But can the code reader also read the truck's computer?
If you get a code reader made to read gasoline and diesel-powered systems, you can use it for both trucks and cars. While some code readers and scanners are designed exclusively for vehicles, others can be used with both cars and trucks. Although some still have a 16-pin connector, the majority of semis have a 9-pin connecting port. Most medium and light vehicles utilize the standard OBD2. The smaller vehicles may be scanned using the code reader in your car.
To work on OBD2 and 9-pin connector ports, however, the majority of high-end diagnostic equipment include adaptors. Find out what color the port is if your truck has a 9-pin adaptor. Green indicates a faster speed, while black indicates a somewhat slower speed. Heavy-duty scanners like the Ancel HD3300 can scan computers in cars and trucks.
How Does the Truck's Scanner Operate?
In essence, reading codes from a truck is similar to reading codes from a car when utilizing a scanner or code reader. The type of connector port utilized in the car is the sole difference. Some code scanners only come with the 16-pin cable; in order to scan your truck, you must purchase the 16-pin to 9-pin adaptor separately. However, if you own a small or medium vehicle, it most likely already has an OBD2 connector, saving you the hassle of purchasing an adaptor.
Once you have the adapter, you may read trouble codes from your truck by connecting it to your scanner's 16-pin cable and inserting the green head into the connector. If you attach a Bluetooth module to the adapter, it will also function with the module. The code reader has the ability to read fault codes and carry out sophisticated diagnostics.

How to Check Your Car or Truck
A code reader is necessary, but if you don't know how to use it, you're better off without one. Here's how to use your code reader to extract codes from your automobile or truck.
- Find the Diagnostic Link Connector/Port in Step 1 Your vehicle has an OBD-2 connector if it was built in 1996 or later. Your truck has a 9-pin plug under the dash if it was made after 2016. Check your owner's manual if you can't find the connectors. If you don't have it, use the internet to find the connector for your particular vehicle model.
- Connect your code reader to the connector in step two. The ignition of your automobile or truck should not be running when you plug in your code reader. Connect to the adaptor first before plugging it into the connector if you are connecting to your truck. Turn the ignition to idle while the cable is connected. The screen of the code reader will also turn on.
- Enter the Required InformationA distinctive vehicle identification number (VIN) identifies your car or truck. A more sophisticated scanner will recognize the VIN on its own. You'll have to manually enter that info if you choose a less expensive one. The code reader could also inquire about the model and specifics of your engine. The lower corner of the windshield is where you may find the VIN.
- Obtain the troubleshooting codes. The core reader will start sharing DTCs from your truck or automobile computer as soon as the information is entered. Both active and pending codes are displayed. The check engine light is set off by the active codes. On the other hand, pending codes show information from the emission control system. A pending code that appears more than once causes the check engine light to come on.
- Recognize and Decipher the Codes You can navigate the menu using the scroll keys now that the codes have been displayed. To be able to locate the issues with the systems, you must be able to decipher the codes. Each code begins with a letter, then four numbers. One of the following could make up the initial letter: P, B, C, or U stand for, respectively, powerplant, body, chassis, and undefined.The first number might be either manufacturer- or generic-specific, the second one denotes the component of the vehicle, and the final one identifies the precise problem. The meaning of the code is available online. The code scanner's instruction manual is also available for usage.

On the other hand, the Ancel HD3300 scanner is suitable for both types of trucks. If you're a car or truck driver looking for a practical, affordable multipurpose scanner, this is the best choice.
