Thanks CamGTP , very much appreciated , I will do that .
Also , is there a "level sensor " to detect the angle of the vehicle and if so , where would it be ..... Thanks again
Hello all , I have a 2017 GMC Savana and while driving on a levelled roar without pulling anything , and at about 60-80 Km , the “grade braking “ comes on .
Push the trailer button and it goes off .
Any ideas why this is happening ?
Thank you .
