## What is Truck Explorer?

Truck Explorer® is a unique tool on the market for special operations on MERCEDES, MAN, IVECO, Freightliner, MAZ, KAMAZ, CLAAS, PONSSE, UNIMOG and other trucks, buses and industrial machines. It allows to read/write memory (FLASH/EEPROM) of ECUs, make IMMO OFF operation, program new keys, calculate special access codes (VeDoc X1, X2, X8; FDOK XT, XN etc.). 

Most of operations can be easily done via OBD port without any ECU disassembling or soldering works. This feature makes Truck Explorer® a must-have tool for independent truck repair workshops and chiptuning service providers.

WARNING: External VEI® (Vehicle Explorer Interface®) device V6 and special license are required to run this software. Please visit www.autovei.com or www.truckexplorer.pro to obtain them.

For different vehicles brands we offer additional accessories and software licenses.

## Key features

- ECU memory read/write (FLASH/EEPROM)
- IMMO OFF operation
- New key programming
- Special access code calculation
- OBD port operations
- Support for multiple truck brands
