[CA11] NO DRIVER DETECTED
I have an autopilot p70 and EV-100 installed. It used to work just fine, now when turned on it is in standby mode and when I push "auto" it responds "no driver detected". The ACU 100 box is flashing red. I wonder what is wrong, how can I find the problem??

RE: [CA11] NO DRIVER DETECTED
Welcome to the Raymarine Forum,

The reported symptom may be indicative of poor autopilot drive unit motor, a failure of the drive unit, or a failure of the ACU (either in its SeaTalkng / NMEA 2000 communications circuitry or within its circuitry responsible for powering the drive unit). I would be recommended that the diagnostics features Data Master MFD's or that of the autopilot control head be used to verify communications with the ACU. Should no communications with the ACU be verified, then it would be recommended that its SeaTalkng / NMEA 2000 plug be disconnected from the ACU and from the backbone's spur socket, that it then be reconnected, and that the test be performed again. Should the problem persist, then it would be recommended that the spur socket to which the ACU is presently interfaced be tested by connecting another one of the system's devices to that spur socket to verify the operational state of that portion of the backbone. Should the interfaced device communicate with the system's other devices, then it would indicate a problem with the ACU necessitating that it be sent to Raymarine’s Product Repair Center to be bench checked / serviced. Should communications between the ACU be verified, then it would be recommended that the autopilot drive unit be tested. Should no fault be found with the autopilot drive unit, then it would be recommended that the ACU be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
