and another try them all
most times I found its not software issue but the chip inside the ELM cable.
I hate these ELM cables and Bluetooth , I prefer a tool , and I have read there are a few that will read/clear errors from CRD, but as long as your engine light is not on , then take the battery off , clean the connection on the battery , L@@K at the module in the passenger side door , it also contains the antenna wire. and check the motors for the locks and wires that run up to the sensor to the drivers side key lock.
