PROGRAM FOR RENAULT ENGINE CONTROLLERS COMMUNICATING THROUGH CAN BUS ON 250 AND 500 Kbps.

For proper operation, we need to program the CAN speed on which the ECU operates and the 6-byte ISK code from the ECU.

In the cell at address 0x01, we enter CAN bus speed value 50 or 25, which gives 500 Kbps or 250 Kbps respectively.

In the cell at address 0x02, we have a value of 0xFF which sets automatic recognition of the type of immobilizer library used in the ECU.

In cells starting from address 0x10, enter the 6 bytes of ISK code from the ECU that we intend to unlock. An example ISK code: A5 A5 A5 A5 A5 A5, is factory programmed into the UNICAN emulator.

In the case of many types of Renault ECUs, appropriately restoring the ECU to a 'virgin’ state will result in the data from the emulator being rewritten to the controller during the auto-adaptation procedure when the power is switched on.

Four wires should be connected: CAN-H, CAN-L, GND (ground) and +12 V IGN ( terminal „15”) or +12 V after the ECU/ECM relay. Ensure the connection adheres to the vehicle’s repair schematics.

The colors of the corresponding wires are specified in the photo.

The location of the eeprom 24C02 memory is also specified in the photo.

Please remember the CAN terminator – terminator resistor, is in many cases indispensable especially when the ECU works standalone.

The description of the green and red LEDs can be found in the photo, thanks to them we can carry out diagnostics of the emulator connection, they clearly indicate the current status of the CAN bus connection and the status of matching to the ECU.
