RET.A

Adapter for connecting SIRIUS 31H, SIRIUS 32, SIRIUS 32N, EMS3132 controllers to the Renault ECU Tool interface

This adapter enables safe and convenient connection of SIRIUS (31H, 32, 32N) and EMS3132 controllers to the Renault ECU Tool diagnostic interface. The adapter is powered by an external 12V power supply and allows communication with the controller via both the K and L lines and the CAN bus, depending on the ECU version.

This solution provides users with access to a range of service and diagnostic functions, such as:

ECU Identification – Ability to read software version, VIN, immobilizer parameters, and other identifying data.

EEPROM (emulated) Memory Reading and Writing – Access to the EEPROM area stored within the FLASH memory, with the ability to modify data.

FLASH Memory Reading and Writing – Full support for reading and writing the FLASH memory content within the ECU, allowing for archiving or modifying control maps.

ECU Reset to Virgin – This function restores the ECU to its factory state (erases the immobilizer code). NOTE: After a reset, the ECU requires an immobilizer signal for proper operation, which can come from the vehicle or an additional emulator installed within the ECU.

Intuitive Editing of the Read Memory – Renault ECU Tool software allows for convenient checking and correction of checksums (CRC), resetting to the VIRGIN state, and performing the IMMO OFF procedure.

The adapter is an indispensable tool for electronic workshops, diagnosticians and people servicing engine controllers in Renault vehicles.
