Key Features
Protect the 40 cm Adapter During Repeated Handling
Pure Copper Core
The internal pure copper core helps provide faster data transmission and more stable diagnostic communication.
Nylon Braided Sleeve
The protective nylon braided sleeve helps reduce wear from bending, pulling, and daily workshop use.
Flexible Insulated Jacket
The outer material is designed to be flexible, insulated, non-toxic, and easier to route around the vehicle during testing.
Enhanced Cable Build
AUTOOL applies automatic production technology and multiple inspection steps from injection to molding for consistent cable quality.
Frequent Plugging Design
The connector is designed for repeated diagnostic use and can be plugged more than 10,000 times under normal use conditions.
Compact 40cm Length
The 40cm cable length keeps the connection manageable while providing extra reach between the BMW 20Pin socket and the scan tool.
BMW Socket to OBD2 Tool
The adapter connects a BMW 20-pin diagnostic socket to a compatible 16-pin OBD2 connector, with a pure copper core for data transmission.
Reinforced Cable
A 7.00mm cable body supports repeated handling.
Passive Adapter Connection
Routes the stated BMW 20-pin connection to a compatible 16-pin diagnostic tool; available functions still depend on the vehicle pinout, scanner hardware, software, and protocol support.
Adapter Function Limits
This passive adapter adds no scan functions or protocol conversion and cannot diagnose a vehicle by itself.
Connector Fit Check
Check the pin type and connector direction before connecting the cable to avoid poor contact or incorrect connection.

How to Use
Connect, Route and Check Communication
Confirm The Vehicle Port
Identify the exact vehicle connector, year, and pinout; inspect it for damage.
Confirm The Tool Chain
Verify the scanner, software, protocol, module, task, and any authorization independently of the cable.
Connect Safely
Follow the vehicle and tool procedure, align connectors correctly, and never force a mismatched plug.
Route Without Strain
Position the cable away from pedals, sharp edges, heat, moving parts, and pinched trim.
Verify Communication
Run the intended read-only connection check first. If communication changes, remove added devices or the extension and compare direct connection.
Safety & Compatibility
Check Pin Fit, Routing and Power Limits
Cable Function
Use the cable for physical connection and routing; protocol and diagnostic functions come from the vehicle and connected tool.
Match the Pinout and Tool
Match the connector and pin routing to the vehicle and diagnostic tool.
Vehicle Movement
Keep all cable and device parts clear of pedals, steering, seat tracks, doors, and driving controls.
Electrical Load
Do not attach unknown or high-current devices to vehicle diagnostic power. Follow the vehicle and tool current limits.
Disconnect If Unstable
If a tool drops connection, overheats, resets, or changes vehicle behavior, stop and return to a known direct connection.
Care and Safety Notes
Keep the connector pins clean and dry. Avoid storing the cable with heavy objects pressing on the connectors.
