You need a working car from which the power steering module and the so-called CAN Bus Sniffer originate
1. Connect the CAN-Bus Sniffer to the vehicle's power supply
2. Connect the wires to the CAN bus on the booster module
3. Select the required CAN bus speed
4. Receive the correct CAN frames while the booster is running in the vehicle.
5. Save the correct frames in the software.
Assemble the booster installation on the table.
Send the correct CAN frames previously saved by CAN-Bus Sniffer to the booster controller.
Simulate the CAN messages sent to the booster module and observe the response.
That's it in a nutshell ...
Once you are at this stage, describe the progress.
Write what you want to use this power steering module controlled by "buttons" for ?
I hope you don't want to eliminate the steering wheel from the car ?
It is possible to do things completely differently.
This is what the "example wires" for the power steering motor going into the controller look like.
EPS typically uses a three-phase BLDC or permanent magnet synchronous motor, which is electronically controlled from the EPS controller.
Make or adapt a new (different) controller.
You just need to verify exactly what type of motor it is ?
