Features: It supports nine kinds of standard protocols, such as vehicle fault diagnosis and real-time data flow. It can print the data stored in the code reading card through USB serial port, and has the data of emission detection and USB upgrade function.  This is a multi-functional code reading card integrating detection, battery detection and printing (serial port printing) for OBD card, providing accurate vehicle detection and battery.  It can test the cold start current, internal resistance, battery life and residual power of 12V start-up lead-acid battery quickly, and determine whether the battery needs to be replaced.  Cell: real time voltage detection, battery impedance detection, how much electricity is left after a period of full charge (SOC), battery charging current value (soh), and Cold start current detection (CCA.  Supported vehicle data: read diagnostic trouble code, clear fault code, engine speed per minute (RPM), calculated load value, calculated load value, coolant temperature, fuel system status, vehicle speed, short-term fuel condition, long-term fuel condition, intake manifold pressure, injection lead time.   Supported protocols: SAE 0 J1850 PWM （6 41.6 Kbaud ）;  SAE 0 J1850 VPW （4 10.4 Kbaud ）;  ISO 9141-2 （5 5 d baud 4 init,10.4 Kbaud ）;  ISO 4 14230-4 KWP （5 5 d baud 4 init,10.4 Kbaud ）;  ISO 4 14230-4 KWP （t fast 4 init,10.4 Kbaud ）;  ISO 4 15765-4 CAN （t 11bit 0 ID,500 Kbaud ）;  ISO 4 15765-4 CAN （t 29bit 0 ID,500 Kbaud ）;  ISO 4 15765-4 CAN （t 29bit 0 ID,250 Kbaud;   Specifications: Main control chip: stm32f103vet6;  Working voltage: DC 12V;  Working current: 98 Ma;  Operating environment: - 20 ~ 70 ℃;  Storage temperature: - 20 ～ 80 ℃;  Supporting languages: German, Dutch, English, Spanish, French, Italian;  Package size: 181.5 * 81 * 29mm;  Package weight: 168g;   Package include: 1 * Scanner;  1 * OBDII Cable;  1 * User Manua
