If the blue light of D4P control unit is blinking and after a short time it switch off, is that it is not detecting the vehicle CAN BUS. If it D4P control unit can not detect the CAN the system will power to off. It’s an interesting way to check if you have connected the CAN BUS backwards. Check your connections. Remember that some models have the connection information directly into the CAN BUS Vehicle record database Digi4Park® in the web.
