There are a lot of mechanical and electronic parts in modern cars. Many functions are fully automated and run through the car’s command unit. As a result, driving a newer car is easier and safer than ever before. Furthermore, several sensors are fitted in modern cars to monitor function and collect data on the machines’ performance. The sensors also help to identify the site and nature of any fault that develops in the vehicle’s system. A fault reader is a special diagnostic tool that allows truck operators to identify faults. The device is hooked to the truck’s electronic control unit that generates codes whenever something is performing sub-optimally.

How does it work?
A fault reader is quite simple to operate. The reader is hooked up to the electronic control unit to run a diagnostic. Afterward, the reader generates onboard diagnostic OBD II codes that represent faults in the vehicle’s functions.
The technology of fault readers has come a long way. The initial designs were basic, but the fault codes were more difficult to read since every manufacturer used different coding systems. As a result, OBD II codes were developed in 1996 to harmonize diagnostics and standardize the format for fault codes. Currently, there are several universal fault readers that work well for different types of trucks.
Reading codes
OBD II codes are relayed as Diagnostic Trouble Codes (DTC), which have a five-digit format. The first digit is a letter and represents the location of a fault in the vehicle system. P, B, C, and U represent the powertrain, body, chassis, and network, respectively.
The second digit on the code identifies the fault as generic or manufacturer-specific. 0 represents the former, while 1 shows a manufacturer-defined problem. Finally, specific details on the location of a fault on the circuit of the vehicle are described with the last 3 digits.
The entire code gives a clear direction of where a fault is and what it is. As a result, appropriate actions can be taken to complete the repair.
Leading readers
Universal readers are common, but only a few brands have reliable results and wide applications. The Bosch Heavy Duty Scantool is an excellent diagnostic device that reads OBD II codes and satisfies the SAE standards for heavy-duty communication systems. Furthermore, the device can run updates that allow it to read faults in the latest vehicles and electronic control units. The Scantool can also run diagnostics on the engine, transmission, and braking systems. It’s powered by a 12V or 24V battery that allows portability. As a result, the Bosch Heavy Duty Scantool is the perfect fault reader for field repairs.
The Jaltest PTE is another household name in the world of fault readers. The unit runs a user-friendly interface that improves usability and fault diagnosis. The device also has a robust case for extra protection and portable functionality. It can assess electrical signals, communication lines, and lighting devices on trucks.
The advantages of a fault reader
Fault readers have made it easy to repair trucks. The device accurately identifies faults and streamlines repair efforts. Furthermore, fault readers confirm successful repairs through a diagnostic evaluation of the electronic control unit. Therefore, if you install aftermarket parts for European trucks, the reader will determine if the replacement is compatible. Since a fault reader makes it easy and fast to diagnose faults, it drives down the cost of repairs.
Truck repairs are inevitable: therefore, it’s imperative to invest in a fault reader that improves the accuracy of diagnostics and efficiency of repairs.
