At CATA Electronics, we understand the importance of precision when diagnosing issues with electronic car modules. Whether it’s an Engine Control Unit (ECU), Transmission Control Module (TCM), or Body Control Module (BCM), our diagnostic process begins the moment we receive your core module.

Our skilled technicians utilize advanced diagnostic tools specifically engineered to interface directly with electronic car modules. These tools communicate with the module to retrieve and analyze diagnostic trouble codes (DTCs), providing a clear picture of any faults present.Reading and interpreting these codes is critical—it enables us to determine whether the issue stems from the hardware, software, or external wiring systems. This level of detail helps us accurately assess the module’s condition and streamline the repair or remanufacturing process.
