Car Scanners

Car scanners , also known as OBD diagnostic tools, are essential devices used to identify and troubleshoot faults in modern vehicles. As today’s cars rely heavily on electronic control units (ECUs), car scanners enable technicians to communicate directly with vehicle systems to retrieve data, read fault codes, and ensure the vehicle is running at optimal performance.

How Car Scanners Work

Car Diagnostic Tools

Car scanners connect to the vehicle’s OBD-II (On-Board Diagnostics) port or diagnostic interface. They extract information from multiple control modules such as:

Car Diagnostic Tools

• Engine Control Module (ECM)

• Transmission Control Module (TCM)

• ABS & Airbag Systems

• Body Control Modules

• ADAS & Safety Systems

• Hybrid/EV Battery Management Systems

Through this communication, scanners provide detailed data for accurate diagnosis and repair.
