Client received a Towing alarm from his truck via priority sms to his cellphone. He did inform us that his vehicle was in for a service. We had a vehicle close by and went to check if all was ok.
The unit sent out an alarm as soon as the mechanics tilted the cab forward and altered the units horizontal axis without acceleration.
The unit interprets this as a towing hitch up and immediately starts to alert.
Happy to report all was in order!
