I need to read parametres like RPM of the engine from siemens sim2k-34vr ECU from obd2 port through K-line protocol,I tried standard service id 0x01 to read current data but ECU said 0x01 service id is not defined, Is there any documentation to find service ids of Siemens ECU?

Thank you.

I found its PIDS is under MODE 0x21 and PID 0x01, I hope it helps to other peoples.
