Reverse engineering LIN bus on E-bike system
As a starter point I would hookup your rigol ds1054z via usb to sigrok
https://sigrok.org/wiki/PulseView this will enable you to log dump and analyze your lin frames . It has a frame decoder for LIN protocol.
This should give you a great view of what is transiting over the lin bus and which slave PID to call .
From there you may use a macchina.cc  to comunicate over lin or use
https://github.com/macchina/LIN with a arduino due and a lin tranceiver.
