This is very useful info and thinking pizzaguy.

So the codes are slow locking action and therefore not triggers for the siren. None-the-less, I may have a failing pump or hose leak, and should get that replaced.

If there was a (false) intrusion detection, wouldn't that trigger am intrusion code record as well. There isn't one, meaning it is not falsely detecting an intrusion.

So the towing sensors might be malfunctioning.

My tasks this weekend are to check the trunk for water intrusion.

I'll get my auto electrician to check the micro-controller and the towing sensors.

I'll replace the locking air tubes, and check the pump pressure.

Thank you again.
