This is a specialized utility from Codecard.lt designed to repair and synchronize the immobilizer data between the Central Electronic Module (CEM) and the Engine Control Unit (ECU). It is specifically for Volvo S60, S80, V70, XC70, and XC90 models from the years 2000-2004. This tool is essential for solving common "no start" problems that arise when the synchronization data between these two critical modules is lost or corrupted.
Common Problems This Tool Solves
• The car doesn't start after a battery problem or if the CEM connection was loose.
• The motor ECU has active fault codes like "No communication with immobilizer" or "Key is not valid".
• The original motor ECU has been replaced with a used one and needs to be adapted to the car.
• The original CEM immobilizer data has been corrupted (shows as "000000") and needs to be restored.
How It Works
The software's core function is to transfer the synchronization and key data from a CEM EEPROM dump file to an ECU EEPROM dump file. To use this tool, you must first read the memory chips from both modules using a compatible programmer (like ELNEC BEEPROG or CarProg).
• CEM Memory Chip: 28F400
• ECU Memory Chips: 93C56, 24C04, or 95P08
Key Features
• CEM to ECU Synchronization: The main function allows you to open a dump from the CEM and a dump from the ECU, and then synchronize the data from the CEM to the ECU with one click.
• CEM Data Restore: Includes a special "RESTORE CEM DATA" button for the specific case where the original CEM immobilizer data is lost or corrupted.
• Simple Interface: A clear, two-panel layout for the CEM and ECU makes the synchronization process straightforward and easy to follow.
System Compatibility
This software has been fully tested and is confirmed to be working perfectly on Windows 10 LTSC (2019).
