Launch X431 ECU Programmer and X431 X-PROG3 PC Adapter streamline the cloning process of Nissan Engine Computers, specifically for models like the 2014-2017 Nissan Leaf (23740-3Nxxx-Gen1_SH72531). The beauty of this procedure lies in its simplicity – no need for an X431 tablet.
Vehicle model and ECU model:
i.e. 2014-2017 Nissan Leaf 23740-3Nxxx-Gen1_SH72531
How to connect:
Open LAUNCH X431 ECU software, input 23740 to quickly find the corresponding ECU model, then double-click it to check the direct connect of diagram.
Follow this wiring diagram to connect the Launch tool and ECU, and connect the Launch tool to the computer via USB cable. (If using It is XPROG3, you need to use XPROG3 PC Adapter in this process)
Here’s a concise operation guide:
Step 1: Backup Original Nissan ECU EEPROM & FLASH Data.
Open X431 ECU & TCU Programmer software or X-PROG3 PC software.
Connect ECU.
After connected, read EEPROM and FLASH data separately, and save the data after reading.
Disconnect the ECU connection.
Step 2: Backup New Nissan ECU EEPROM & FLASH Data
Connect X-431 ECU & TCU Programmer/X431 X-PROG3 to a new Nissan engine computer.
Repeat the same steps as step 1 to connect ECU, read and save new EEPROM and Flash data in sequence.
(This step is a disciplined operation. In order to prevent bricking, develop a good habit)
Step 3: Write EEPROM and FLASH data
Select the EEPROM and Flash data of the original Nissan engine computer and write them into the new one respectively.
Disconnect after data writing is completed.
