How to use Launch X431 DoIP Cable 16Pin

LAUNCH X431 is a well-established brand in automotive diagnostics, offering versatile tools that support various diagnostic protocols, including DoIP (Diagnostics over Internet Protocol). DoIP is essential for diagnosing modern vehicles, especially as cars become more connected and reliant on digital communication.

In this article, we will explore how to connect different LAUNCH X431 devices to perform DoIP diagnostics, using specific Vehicle Communication Interfaces (VCIs) and cable requirements.

What is DoIP?

DoIP stands for Diagnostics over Internet Protocol, a diagnostic method used primarily for modern vehicles equipped with advanced electronic systems. It allows the diagnostic tool to communicate with a vehicle's control units over a high-speed Ethernet connection, offering faster and more efficient data transfers compared to older protocols.

LAUNCH X431 DoIP Connection Scenarios

Depending on the LAUNCH X431 model and VCI (Vehicle Communication Interface) being used, different cables and setups are required for DoIP diagnostics. Here’s a breakdown of the typical setups for various scenarios:

Case 1: Using Smart Box VCI with X431 PRO 5

• VCI: Smart Box
• Device: X431 PRO 5

For the X431 PRO 5, when using the Smart Box VCI, a USB Type B to Micro USB cable is required for DoIP diagnostics.

• Note: The new X431 PRO 5 models are equipped with SmartLink VCI, eliminating the need for additional adapters for DoIP diagnostics.

Case 2: Using DBScar VII VCI with X431 PRO 3

• VCI: DBScar VII
• Device: X431 PRO 3

The X431 PRO 3, when paired with a DBScar VII VCI, requires a USB Type A to Type B cable for performing DoIP diagnostics.

• Note: Similar to the PRO 5, the new X431 PRO 3 models come with SmartLink VCI, eliminating the need for additional adapters for DoIP diagnostics.

Case 3: Using DBScar VII VCI with LAUNCH X431 Devices

• VCI: DBScar VII
• Devices:
  • CRP919E BT
  • CRP919X BT
  • Pro3 APEX / X431 PRO3 ACE
  • ProS V5.0
  • Pro3S+ V5.0/ V+ V5.0
  • IMMO Plus
  • IMMO Elite
• Connection Cable: Launch X431 DoIP Cable (16Pin)

In this scenario, X431 devices like CRP919E BT, CRP919X BT, Pro3 APEX, and others must be used with a Launch X431 DoIP Cable (16Pin) for DoIP diagnostics when paired with the DBScar VII VCI. The DoIP Cable is specifically designed for these devices and works only with DBScar VII VCIs.

• Note: Some of these devices are also equipped with SmartLink VCI, providing an alternative method for performing DoIP diagnostics without needing the additional cable.

Case 4: Using DBScar IV VCI with PAD III and PAD III V2

• VCI: DBScar IV
• Devices: PAD III, PAD III V2
• Connection Cable: BMW F-chassis ECU Programming Cable

For devices like PAD III and PAD III V2, which are typically used for high-end diagnostics and ECU programming, a BMW F-chassis ECU Programming cable is required for DoIP diagnostics when using the DBScar IV VCI.

Case 5: Using SmartLink VCI

• VCI: SmartLink / SmartLink 2.0 VCI

The SmartLink VCI provides a direct method for performing DoIP diagnostics without the need for any additional cables. This makes it the most straightforward and user-friendly option for mechanics and technicians performing DoIP diagnostics.

Conclusion

Since the release of SmartLink, DoIP diagnostics have become very simple, and most diagnostics can be completed directly using SmartLink to connect the vehicle and the device, without the need for additional cables.
