Default OBD 2 Diagnistic tool $16.95

I bought one of these last week. It uses WiFi and there are several apps that will work with it. It is WiFi linked to your phone. Maybe it would help. See if you are getting the speedo pulses at the OBD port anyway. For the price I got two. One will remain in the coach.
