Edrive Shangai controller error code alarm

Hello, I´m tring to fix my small electric car, it is a very common car around the world but I try to track down the model but it is impossible to find out any manual or data sheet.

Perhaps some one here can help me.

The car turns on, and everything works but it does not accelerate or move and an error code alarm sounds that makes 6 short beeps and one long beep.

I attach some pictures of the car, controller and motor.

Regards!
