This product is a 16 pin full pin (fully connected) straight through (fully connected) OBDII adapter device. Its core function is to extend or convert the OBDII diagnostic interface of the vehicle into a more easily connected form without loss. All pins (Pin 1 to Pin 16) are connected one-to-one, without any resistors, chips, or signal processing circuits inside, ensuring 100% authentic transmission of diagnostic signals.
This product is mainly used for professional and modification scenarios such as automotive diagnosis, ECU flashing, data monitoring, equipment transfer, etc.
Product Features
- Full pin connection: It fully supports the 16 pins of the OBDII interface, ensuring smooth signal transmission for all protocols (such as CAN bus, K-Line, L-Line, etc.).
- Non destructive direct connection: The internal wiring is directly connected without any signal attenuation or modification, ensuring the originality and accuracy of diagnostic data.
- High quality craftsmanship: Made of high-strength and wear-resistant ABS+PC flame-retardant materials for the interface, with nickel-plated pins that are resistant to oxidation and corrosion, ensuring good contact even after multiple insertions and removals.
- Plug and play: No driver required, no external power supply needed, plug in and start to use.
Applications
- Vehicle diagnosis: Connect diagnostic computers (such as X431, Daotong, Snap on, etc.) to the vehicle OBD interface.
- ECU calibration: Provide stable connection for ECU flashing programs (such as ATP, CMD, KESS, etc.).
- Data monitoring: Connect HUD displays, vehicle status monitors, and other devices.
- Interface extension: When the original vehicle OBD interface is located in a narrow or inconvenient position for insertion and removal, it can be extended to a convenient operating position through this adapter cable.
- Modified vehicles: commonly used for modified vehicles that require additional OBD devices to be connected.
Interface Definition (Pin Description)
This product is a straight through OBDII adapter, and the pin definitions of the male and female sockets are completely consistent, in compliance with the international OBD-II standard. Please note that the pin function definitions may vary among different vehicle models, and the product here is using the standard definition.
Instructions for Use
- Connect the vehicle: securely connect the male end of this adapter to the original OBD-II diagnostic interface of your vehicle.
- Connect the device: Insert the plug of your diagnostic device, programmer, or other OBD device into the female end of this adapter.
- Start the device: Turn on the vehicle power (usually to ON, no need to start the engine), and then start your diagnostic device for operation.
- Disconnect: After use, turn off the diagnostic equipment first, then turn off the vehicle power, and finally unplug the plugs at both ends.
Precautions and Safety Warnings
- Safety First: Please perform plugging and unplugging operations when the vehicle is turned off or in OFF/ACC state to avoid damage to ports or devices that may be caused by live plugging and unplugging.
- Compatibility: This product is a physical connector and cannot provide protocol support for decoders that do not support your vehicle protocol. Please ensure that your diagnostic equipment supports your vehicle.
- Protection Interface: When plugging or unplugging, please align with the pins and do not use brute force to prevent the pins from bending or breaking.
- Storage Environment: Please place in a dry and clean environment, avoiding high temperatures, humidity, or strong magnetic fields.
- Professional Use: This product is designed for professional automotive diagnosis and maintenance. Non professionals are not allowed to connect unknown devices on the vehicle at will to avoid causing vehicle malfunctions.
Troubleshooting
Phenomenon | Possible Causes | Solutions |
Diagnostic equipment cannot connect to vehicle | Diagnostic equipment incompatible with vehicle protocol The fuse of the vehicle OBD interface is blown | Confirm equipment and vehicle compatibility Check the vehicle fuse |
The connection is unstable and the data is intermittent | The adapter is not securely inserted Interface pin oxidation or poor contact | Check if the connections at both ends are secure Clean interface with electronic contact cleaner |
