1. A good assistant in a repair shop: When you repair a certain module of the car, CTB003 can help you test whether it can work properly without loading the car. 2. CTB003 does not require learning CAN analyzer software to use, making it convenient for workbench testing and eliminating the need to connect to a computer. 3. CTB003 can be reused. If you want to fix the vehicle model and module to use it, after recording data and completing the test, you can remove the "IN" button to avoid accidentally touching and losing data. Note: Short press of the "IN" key will not overwrite the data. Only after long press of the IN key and successful recording of data will the previous data be overwritten. 4. The computer can import data into CTB003 through a professional CAN BUS analyzer. Applicable scope: 1. Activation of comfort systems such as instrument cluster, entertainment host (large screen), and operation panel, also include HMI (Human Machine Interface), IP(Instrument Pack), EPS(Electric Power Steering), EWP(Electric Water Pump), EACC(Electric Air Conditioning Compressor),etc. 2. CTB003 Support electronic module without handshake protocol or timing synchronization, and also support the data that can be recorded and played by professional CAN analyzers. (Do not support IMMO) CTB003 Support to import data from computer directly. Note: 1. Do not support data storage on computers; 2. Cannot perform data analysis, and can only save the last recorded data in the MCU. 3. Due to differences in data for different vehicle models and modules, the recording speed and playback activation operation may vary. 4. Do not support IMMO.
