P1934 & P0500 are both vehicle speed signal faults.
If vehicle won't start/move this must be a can/comms error not passing info between PCM/IC/ABS. (Or other modules as I posted previously)
From elsewhere.
Hello. These are all, effectively, vehicle speed errors. P0500 = vehicle speed sensor A. U0073 = control module communication bus A off. P1934 = vehicle speed signal. These will all be processed through the CAN BUS communication from the ABS module and then the body module before being read in the PCM
