Good to Know
Caution
- This is not a diagnostic scanner. A 16-pin scan tool that supports the Mercedes-Benz model, protocol and system is required and sold separately, along with any software or licenses.
- Do not attach unknown or high-current devices to vehicle diagnostic power; follow the vehicle and tool current limits.
- If the tool drops connection, overheats, resets or changes vehicle behavior, stop and return to a known direct connection.
Care
- Keep the connector pins clean, dry and free of debris before use.
