1. A reliable tool for automotive repair shops: CTB003 enables functional testing of vehicle modules without requiring the full vehicle to be connected. 2. CTB003 requires no CAN analyzer software setup, enabling quick and convenient bench testing without a computer connection. 3. CTB003 is reusable. After recording and completing a test, press and hold the “IN” button to save data; the device retains only the most recent recorded data. A short press of the “IN” button does not overwrite existing data—only a long press confirms new data recording and replaces prior data. 4. Data can be imported from a computer using a professional CAN BUS analyzer. Compatible Applications: - Activation testing for comfort systems including instrument clusters, infotainment hosts (large displays), control panels, HMI (Human-Machine Interface), IP (Instrument Pack), EPS (Electric Power Steering), EWP (Electric Water Pump), and EACC (Electric Air Conditioning Compressor). - Supports electronic modules that do not require handshake protocols or timing synchronization. - Supports playback of data captured and saved using professional CAN analyzers. - Supports direct data import from a computer. Important Notes: - Does not support data storage on external computers. - Does not perform data analysis; stores only the most recently recorded data in the MCU. - Recording speed and playback behavior may vary depending on vehicle model and module specifications. - Not compatible with IMMO (Immobilizer) systems. Note: Product design or appearance may vary slightly between production batches. Material: Plastic Color: As shown
