Psa Interface Checker 440 Link

Confirm that the LIS receives the expected simulated value.

When a multiplexer falls into a loop showing an init ko status or struggles to read vehicle modules beyond basic VIN detection, this tool acts as a factory reset mechanism. It rewires the inner flash app block to establish cleaner serial communication.

Replay the callback manually using the stored last_known_payload :

The interface checker reads the microcode stored in the device's main microprocessor. It helps differentiate between restricted units and fully compliant Revision C hardware. Revision C is required to access modern CAN-bus architectures found in newer PSA platforms. Firmware Cross-Flashing
