It can be flashed with the latest firmware (e.g., 4.3.7) without "bricking" or being blocked by Diagbox.

For example, firmware version 4.3.2 indicates compatibility with DiagBox 7.57, while version 4.3.7 works with DiagBox 9.68. Version 4.4.0 supports DiagBox 9.91 through 9.149. This mapping helps users select the appropriate software version for their hardware.

The PSA Interface Checker is a lightweight utility designed to interact directly with the XS Evolution (Lexia 3 / PP2000) diagnostic interfaces. Unlike the heavy DiagBox software, this checker allows technicians to perform low-level operations on the VCI (Vehicle Communication Interface) hardware.

A significant portion of the PSA diagnostic user base relies on Chinese-manufactured clone interfaces, which are functionally similar to genuine PSA hardware but often require additional care in configuration. The PSA Interface Checker has proven particularly valuable for this community, as clone interfaces frequently come with incorrect firmware or serial numbers that prevent proper operation.
