Feature: 1. Supported Protocols: 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 , 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: 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 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 of features.Specification: Item Type: ECU Programming CableProduct Features: 1. Support DC power supply2. Support security protection head super programming special connection port power supply.3. GND4 and GND5 (meet special ECU programming needs)4. With boot GND4 clip, compatible with burning equipment5. 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 . When some ECUs need to connect GND4 and GND5 independently, release the switch6. With ignition analog switch (with 1 and 2 small special ignition wires)7. Support standard full protocol connection (double K line, double CAN line), 3 and 2 small power plugs, 4 GND, 4 small GND8. Equipped with CAN protocol communication resistorsWhat is an analog ignition switch?After the ING ignition switch is pressed, 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.Material: plasticcolour: As ShownPackage Contents: 1 x Jumper CableOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
