B109F Intrusion Sensor
Cannot seem to get rid of this code B109F, it comes back after resetting it. B109F Intrusion Sensor Module "Component Or System Operation Obstructed Or Blocked"
From what I can tell these are the little IR sensors up near the map lights, they look like little tiny speakers? I don't anything clearly blocking them or wrong with them. Any way to trouble shoot this code? Doesn't seem to be much on the internet about it.
