looking for a OBD tester for 2014 Thor Siesta 24ST Diesel
Hi...looking for a OBD tester for my 2014 Thor Seista 24 ST with Mercedes Diesel. Trying to diagnose ABS , Anti traction, & other lite (3 lites total) that all appeared on dash..(& cruise control is now inoperatable.) I've checked all 4 wheel speed sensors & all looked clean & passed resistance tests...any help would be appreciated. Also heard brake lite switch can cause this but it's working fine.
