How to choose the right Autel US patch wire
When selecting a patch wire product from Autel US, first consider the protocols your vehicles use. The MaxiVCI V200 supports DoIP and CAN FD, making it suitable for the latest models. The CAN FD Adapter is a targeted solution for GM vehicles using that protocol. For electric vehicle battery diagnostics, the EV Diagnostics Upgrade Kit is the only option, but it requires a compatible MaxiSys tablet. The VCI Mini is best for older vehicles that only need basic OBDII communication via Bluetooth.
Also check compatibility with your Autel scanner. The V200 works with several models (ITS600, MS906MAX, etc.), while the VCI Mini works with a different list (MS906S, TS608, etc.). The EV kit works only with high-end MaxiSys tablets. The CAN FD Adapter is described as compatible with ‘a wide range’ but Autel US does not specify exact models. Ensure your scanner is listed before purchasing.
What the brand does not state
Autel US does not publish battery life or recharge time for any of the wireless VCI products (V200, VCI Mini). Firmware update frequency and procedure are also not stated. For the EV Diagnostics Upgrade Kit, the specific vehicle models (e.g., which Tesla or BMW years) are not listed. The CAN FD Adapter’s exact compatible scanner list is not provided—only ‘wide range’ is mentioned. Additionally, Autel US does not state the data transfer speed for the VCI Mini or the CAN FD Adapter. Warranty terms beyond the 30-day return policy are not stated; check the product page for any manufacturer warranty.
Frequently asked questions
Are these patch wires compatible with all Autel scanners?
No, each product has specific compatibility. The MaxiVCI V200 works with ITS600, MS906MAX, MK906PRO, MS906PRO-TS, KM100, and BT608. The VCI Mini works with MS906S, TS608, MP808TS, MK808BT, MK808TS, and MK900T. The EV Diagnostics Upgrade Kit works only with MaxiSys Ultra, Ultra ADAS, MS919, and MS909 tablets. The CAN FD Adapter is described as compatible with a wide range of Autel tools, but exact models are not stated by the brand.
What is the difference between DoIP and CAN FD?
DoIP (Diagnostic over Internet Protocol) uses Ethernet for faster data transfer, while CAN FD (Flexible Data-Rate) is an evolution of the standard CAN bus with higher bandwidth. The MaxiVCI V200 supports both protocols, making it suitable for the latest vehicles. The CAN FD Adapter only adds CAN FD support, not DoIP.
Do these products require external power?
The MaxiVCI V200 and VCI Mini are powered via the vehicle’s DLC port (12V-24V). The EV Diagnostics Upgrade Kit’s EVDiag Box likely requires connection to the MaxiFlash VCI or VCMI, which is powered by the vehicle. The CAN FD Adapter is an add-on module that draws power from the connected Autel scanner. Autel US does not specify power details for the CAN FD Adapter.
Can I use the VCI Mini with a newer vehicle that uses CAN FD?
No, the VCI Mini does not support CAN FD or DoIP. It only supports standard CAN, EOBD, OBD, and OBDII protocols via Bluetooth V.2.1+EDR. For newer vehicles with CAN FD, you need the MaxiVCI V200 or the CAN FD Adapter.
What is the return policy for these patch wires?
Autel US offers a 30-day return policy from the date of receipt. Items must be unused, in original packaging, with proof of purchase. Return shipping is free for defective or damaged items; otherwise, the customer pays return shipping. Approved returns are sent to 600 Northgate Pkwy, Suite D, Wheeling, IL 60090.
