Lexus

I have a module attached which produces two square waves at 50% duty cycle at approx 10 volts, one at 82Hz, this feeds into the EPAS on Pin 15 and represents the engine running, the second signal is a variable frequency via a pot and is between 19Hz and 295Hz and feeds into Pin 7 of the EPAS and represents MPH, this pot allows for adjustment of assistance to the steering.
