Hi jmlflorencio, Just checking if you have been able to fix the PAS. I have the same issue with a Fiido D4S. The throttle works, while the PAS doesn't. Thanks!

Hi all and thank you for welcoming me in your community. I’ve recently purchased a second-hand Fiido D4S. Unfortunately, I later realised while the Throttle function works properly, the Pedal Assisted System (PAS) doesn’t work. I removed the controller from the frame and I noticed the PAS Sensor wasn’t connected to anything. After having clarified how the wires are organised by watching some videos, I reconnected the sensor to the controller, but nothing changed. I then tried to clean the PAS sensor, thinking that maybe it was too dirty. I removed it from the bike, opened it, and then cleaned the magnets and the case. This didn’t solve the problem. Thinking that some connections were broken, I replaced the PAS sensor with a new one purchased online but the outcome didn’t change. I then tried to replace the connectors between PAS and throttle but (of course) the communication error E2 showed. So, I’d need the support of this community to solve the problem. I am starting thinking the problem could be due to the controller. Would you know how to reset the controller? The display in use is shown in the following picture. Do you think it can be due to something else? Thanks all!
