WARNING: Safety features are disabled when in diagnostic mode. Do not engage diagnostic mode unless you are willing to accept all the risks associated with it. There is a very real risk of serious injury when safety features are disabled. For example, without the cliff sensors properly functioning, a unit can fall from a great height and hit pets or children causing serious injury or worse.
