The most common code you see with the indicator lights flashing is the 09 Low Freon detected code in Parameter 0.
Another quick wey to tell if the system is low on freon is to let the engine run and turn the A/C on. If the compressor cycles on/off every few seconds, that's an indication that the low side pressure is too low and there is not enough Freon in the system.
