Features: 1.Supported Protocols: OBD2 jumper cable can support multiple protocol communication, including, double K line, double CAN line, J1850, PWM, VPW and other protocols. 2.Function: This jumper cable can be used to connect ECU, read and modify vehicle data, including DTC, vehicle speed, airflow, engine speed, oil temperature and other data. 3.Accurate: Premium explosion proof cable material and metal connectors, precise design and optimized process improve the speed and accuracy of data transmission, which can effectively reduce the error rate of data transmission. 4.Safety: OBD2 jumper cable has excellent isolation technology, effectively prevent equipment failure and other factors from affecting the safety of the vehicle circuit, while not interfering with the vehicle's original data, and will not affect the safety of the vehicle's driving and use. 5.Essential Cables: The diagnostic cable provide support and solutions for professional technicians, automotive enthusiasts and DIY car repair customers with a variety of features. Specification: Item Type: ECU Programming Cable Material: ABS Product Features: 1. Support DC power supply 2. Support security protection head super programming special connection port power supply. 3. Independent GND4 and GND5 (meet special ECU programming needs) 4. With boot GND4 clip, compatible with burning equipment 5. With GND4 GND5 short circuit switch (some ECUs need to switch to short circuit mode when programming) Note: The switch of GND4-5 is always pressed to light up. When some ECUs need to connect GND4 and GND5 independently, release the switch 6. With ignition analog switch (with 1 large and 2 small special ignition wires) 7. Support standard obd2 full protocol connection (double K line, double CAN line), 3 large and 2 small power plugs, 4 large GND, 4 small GND 8. Equipped with CAN protocol communication resistors What is an analog ignition switch? After the ING ignition switch is pressed, the line marked ING12V will have 12v, which is the analog ignition switch. Because when some devices read some ECUs, the device will prompt to turn on or off the ignition switch.
