Launch DOIP Connect Cable for CRP123X/E/I V3, CRP129X/E/I V3, CPR129 PLUS V3

The Launch DoIP Connect Cable is a diagnostic adapter designed to add DoIP (Diagnostics over Internet Protocol) communication capability to compatible Launch Creader Professional V3 diagnostic scanners. It enables supported CRP devices to communicate with modern vehicles that use Ethernet-based diagnostic networks.

The adapter is designed for compatible V3 versions of the Launch CRP123X, CRP123E, CRP123I, CRP129X, CRP129E, CRP129I, and CRP129 PLUS diagnostic scanners. Compatibility should be confirmed with the exact scanner version before purchase.

DoIP stands for Diagnostics over Internet Protocol. It is an automotive diagnostic communication standard that allows diagnostic data to be transferred over IP/Ethernet-based vehicle networks. DoIP is increasingly used in newer vehicles because it can handle the high-speed communication requirements of modern electronic systems.

Some newer vehicles use DoIP for communication with certain electronic control modules. A conventional OBD-II connection alone may not provide access to these systems. The Launch DoIP adapter allows a compatible CRP V3 scanner to communicate with supported DoIP-equipped vehicles.

Yes. The Launch DoIP adapter is designed to provide DoIP protocol support to the compatible CRP123X V3 series, allowing the scanner to communicate with supported vehicles that use Ethernet-based diagnostics.

Yes. The adapter supports compatible CRP129X V3 series diagnostic scanners and expands their communication capabilities to supported DoIP vehicles.

Yes. The adapter is designed to work with compatible CRP123E V3 and CRP129E V3 diagnostic tools, as well as other supported CRP123 and CRP129 V3 variants.

Yes. The Launch CRP129 PLUS V3 is included among the compatible diagnostic tools for this DoIP adapter

Depending on the scanner software and vehicle, DoIP applications include supported models from BMW, Mercedes-Benz, Volvo, Polestar, Jaguar, Land Rover, Volkswagen, Audi, Skoda, SEAT, Bentley, Lamborghini, GM, Nissan, Toyota, Lexus, and other manufacturers using DoIP technology.

Yes. The DoIP adapter supports compatible BMW F, G, I, and U chassis applications. Exact diagnostic coverage depends on the specific vehicle, model year, installed modules, and diagnostic software version.

Yes. DoIP communication is supported on selected newer Mercedes-Benz platforms, including compatible applications from vehicle series such as C-Class, E-Class, S-Class, GLC, GLE, AMG GT, SL, EQE, and EQS. Exact coverage varies by chassis and model year.

Yes. The Launch DoIP adapter supports a variety of compatible Jaguar and Land Rover applications, including selected Range Rover, Range Rover Sport, Discovery, Discovery Sport, Range Rover Evoque, Range Rover Velar, Defender, Jaguar XE, XF, F-PACE, E-PACE, and I-PACE models.

Yes. Supported DoIP applications include selected newer vehicles from Volkswagen, Audi, Skoda, SEAT, Bentley, and Lamborghini. Examples include compatible VW ID-series vehicles, Golf 8, newer Skoda models, and other vehicles using modern Ethernet-based diagnostic communication.

Yes. Supported applications include various newer Volvo and Polestar vehicles. Examples include compatible Volvo S60, S90, V60, V90, XC40, XC60, XC90 and C40 models, as well as Polestar 1 and Polestar 2.

The DoIP adapter uses three connection types: a 15-pin Female connector for connection to the compatible CRP diagnostic tool, a 16-pin Male connector for connection to the vehicle’s Data Link Connector (DLC), and a USB Type-C connector for connection to the USB Type-C port of the compatible Launch CRP scanner.

No. This product is an adapter/accessory, not a standalone diagnostic scanner. It must be used together with a compatible Launch CRP V3 diagnostic device and appropriate vehicle diagnostic software.

The adapter primarily adds the communication capability required for supported DoIP vehicles. It does not independently add reset, coding, or service functions. The functions available after connection depend on the capabilities of your Launch CRP scanner, its software, and the specific vehicle.

No. DoIP and CAN FD are different vehicle communication technologies. DoIP uses IP/Ethernet-based communication, while CAN FD is an enhanced version of the CAN protocol. Some modern vehicles may use one or both technologies. A DoIP adapter should therefore not automatically be considered a replacement for a CAN FD adapter.

The adapter is ideal for professional mechanics, automotive workshops, diagnostic technicians, auto electricians, and advanced users who already own a compatible Launch CRP V3 scanner and need to diagnose newer vehicles that communicate using the DoIP protocol.

The Launch DoIP Connect Cable expands the capabilities of compatible CRP123X/E/I V3, CRP129X/E/I V3, and CRP129 PLUS V3 scanners by enabling communication with supported modern DoIP vehicles. It is a practical upgrade for technicians who work on newer European, Asian, and American vehicles that increasingly rely on Ethernet-based diagnostic networks.
