Lonsdor K518 Pro Replacement OBD Cable

Compatible Connector and Pinout
Replacement cables must match the OBD‑II 16‑pin connector and the correct pin configuration that the K518 Pro uses to communicate with vehicle ECUs — essentially the same as the original cable included with the unit. This ensures proper power and data signals.

✔️ Built‑in Illumination & Visibility
Many genuine and high‑quality replacement cables support OBD port illumination, which lets the K518 Pro light up the OBD plug to help locate the vehicle’s diagnostic port more easily, particularly in low‑light conditions.

✔️ Self‑Test & Hardware Detection Support
Good cables allow the K518 Pro to perform its OBD cable self‑check/hardware detection (checking if any pins are damaged or not connected). If your cable is faulty, the device will alert you during its self‑test check.
