all 3 leds flashing together means the the unit lost power or ground and has reset, 3 flashes means that the bypass module has not been programmed yet to a vehicle during power-up.

 

Please put a digital voltmeter on the red and black wires of the 4 pin datalink connector, 12v should not at any time drop out on while connected to these wires.

I've got exactly same problem. Power is constantly on on black connector, but led's ceep flashing together
leds will flash like that when a module is not programmed to car or if it's not even flashed with firmware.
