bmwcas1.webp


Introducing the CAS1 Editor v1.0, a powerful and free software utility designed for the automotive community, including technicians, programmers, and BMW enthusiasts. This tool simplifies complex tasks related to the BMW Car Access System 1 (CAS1) module, allowing for direct modification of your EEPROM data without the need for expensive software.

Whether you are replacing a faulty CAS unit, synchronizing data after a swap, or need to make specific adjustments, this editor provides a user-friendly interface to get the job done efficiently.

Key Features:
  • Edit ISN: Easily read and write the Individual Serial Number (ISN) to synchronize the CAS module with the engine control unit (ECU).
  • Change VIN: Modify the 17-digit Vehicle Identification Number (VIN) stored in the CAS module, essential when adapting a used unit to a new vehicle.
  • Mileage Correction: Reset or change the mileage value stored in the EEPROM.
  • Key Management: View the status of all 10 key slots, see key IDs, and save key data.
  • Simple Interface: A clean, straightforward layout allows you to open your file, make the necessary changes, and save it with just a few clicks.
Supported CAS1 Modules & Processors:

This tool is designed to work with dumps from the following CAS1 processors (masksets) and EEPROM sizes:
  • 4KB EEPROM Dumps: for modules with 2K79X and 0L01Y (MC9S12DG128/256) processors.
  • 2KB EEPROM Dumps: for modules with 0K50E (MC68HC912DG128A) processors.
Compatible EEPROM Programmers:

To read the data from your CAS1 module and write it back, you will need a compatible hardware programmer capable of handling Motorola/Freescale processors. Commonly used programmers for this job include:
  • XPROG-M
  • UPA-S (UPA-USB)
  • Orange5
  • VVDI Prog
  • R270+
How to Use:
  1. Carefully read the EEPROM data from your CAS1 module using one of the compatible programmers listed above.
  2. Click "Open File" in the CAS1 Editor and load your saved dump file.
  3. Use the dedicated "Change" or "Reset" buttons to modify the ISN, VIN, or Mileage.
  4. Click "Save" to save the modified EEPROM file.
  5. Write the new, modified file back to your CAS1 module using your programmer.
Disclaimer: This is a powerful tool intended for educational and legitimate repair purposes. Always create and verify a backup of your original EEPROM file before making any changes. The user is fully responsible for their use of this software. Modifying a vehicle's mileage may be illegal in your country or region.
