How to permanently deactivate the start&stop system of the Renault Scenic 4

Model: Renault Scenic MK IV, Scenic 4, MK 4, Scenic IV - Years 2016-2022
Part: Onboard computer

Today we will explain how to permanently deactivate the start&stop system on Renault group vehicles, specifically the Renault Scenic 4. To perform this operation, we need to download the ddt program on our computer and purchase a remote communication cable that must be connected to the OBD socket. We open the program on the computer and connect the cable to the OBD port located under the dashboard of the vehicle. We turn on the instrument panel and press the brake pedal while putting the gear in mode in order to keep the instrument panel always active. We connect the socket and start modifying the software. We select the vehicle model and then the "ECU" option, with the cursor we select the "B4" option and then set the "battery group" option. From the battery configuration values table, we select the "start&stop" option and change the value from zero to one, send the command and press the power button twice. A green light will appear on the instrument panel indicating the deactivation of the system. We turn off the instrument panel and disconnect the OBD socket.
