Apple is introducing a new internal USB-C Diagnostic Tool as a successor to its existing Serial Number Reader, which can be used to both collect a device's serial number directly from its logic board and test power on a device itself.

With only a Lightning version previously available, images have surfaced of a new USB-C Diagnostic Tool (UDT) that appears to be known as "ChimpSWD" internally.

The new tool was produced for compatibility with Apple's iPad Pro lineup, which has been USB-C based since 2018.

Let me introduce you UDT (USB-C Diagnostic Tool), probably some of you know it already as ChimpSWD.

Apple has informed service providers that its Apple Service Toolkit 2 diagnostic system has been updated to support HDI Serial Number Reader for the first-generation 11-inch iPad Pro and third-generation 12.9-inch iPad Pro using the new USB-C Diagnostic Tool
