When an auto technician or electronics hobbyist uses an EEPROM programmer (like a UPA-USB, CarProg, or Xprog) to read a 93c86 chip, they extract a raw binary ( .bin or .hex ) file.
using proprietary algorithms, standard EEPROM readers cannot interpret the raw data without a tool like this. Common Use Cases: Dashboard Repair: Reading and writing data to fix corrupted clusters. Cloning/Swapping:
Based on forum archives (from 2007–2012), a tool called “Dejavu” or “Dejavu Decrypter” supposedly allowed users to: dejavu 93c86 decrypter rapidshare
For the "MHH Auto" and "CarTechnology" communities, RapidShare links were the standard way to share documentation, diagnostic software, and yes, even the DeJaVu decrypter. A locked binary file could be uploaded to RapidShare, and the password or link would be shared on a forum post.
If you must run an old 2008-era tool:
The is a common serial EEPROM used in automotive instrument clusters and ECU units. It stores critical data that is often "masked" or encrypted to prevent unauthorized tampering. Capacity: 16K bits of memory. Common Brands: Microchip, STMicroelectronics, and Atmel. Usage: Odometer readings, VIN storage, and security codes.
If you are attempting to program or decrypt a 93c86 EEPROM chip for a vehicle today, relying on legacy Windows XP-era tools like Dejavu is rarely necessary. Modern hardware and software suites have integrated these decryption algorithms into automated workflows. Advanced Hardware Programmers When an auto technician or electronics hobbyist uses
Critical vehicle data (like mileage, VIN, and immobilizer PIN codes) is stored in these chips in an encrypted format designed to prevent tampering. The Dejavu tool is designed to:
