Entering '18 Yamaha R15 diagnostic mode


I tried to make a tool to mimic official YDT tool to read Yamaha R15 engine data. But I cannot enter its diagnostic mode. YDT is using a  LIN Transceiver  TLE7259-2GE to communicate with R15.

When use YDT, it will send 0xFD @ 115620bps baud rate with 16ms interval. And detect a 250ms high (dominated by R15) and then a 25ms low from bike. After that, consequent communication will use 10400bps baud rate.

However, I made a kit which is same as LIN Transceiver as YDT, but still cannot make R15 sending out dominated signal. Anyone knows how to deal with this problem? Or is there development hardware I can buy from internet? In short, I want to make a tool to read R15 engine data without YDT.
