Hi, this is Dusty, I'm one of the auto experts on RepairPal's Car Genius team! The blinking 'D' indicator indicates a problem in the transmission, which is for code 50 (5 blinks) per Honda's documentation there are 2 possibilities, either P0970 or P0971 - Pressure Control Solenoid "C" Control circuit High or Low. This particular pair of faults is caused by an electrical circuit problem, so a professional diagnosis may be necessary to determine if the issue is with the solenoid itself, or within the electrical circuit.
