VIN Patcher

Scan, replace, and verify VINs in module files with automatic CRC correction

How VIN Patching Works

This tool scans for VIN locations in D-FLASH and EEE memory, replaces them with your target VIN, and automatically fixes all CRC checksums. RFHUB modules store VINs in reversed format, which is handled automatically.

Upload Module Files

Upload your BCM (D-FLASH) or RFHUB (EEE) module files to begin VIN patching

Step 1: Scan for VINs

Scan your module files to detect current VIN locations (select D-FLASH for BCM, EEE for RFHUB, or both)

D-FLASH Module (BCM - Optional)

EEE Module (RFHUB - Optional)

Step 2: Patch VIN

Replace the original VIN with your target VIN (at least one module required)

Important Notes

RFHUB VINs: RFHUB modules store VINs in reversed/backward format. This tool automatically detects and handles the reversal.

CRC Checksums: All CRC checksums (CRC-16, CRC-32) are automatically calculated and fixed after VIN replacement.

Final Step: After flashing the patched files, you must complete VIN alignment using professional diagnostic equipment.
