I have two 1997 Ford F250’s I have a brand new Android tablet from RCA. I use an MXBluetooth to connect. All were bought in early January as well as the torque pro app. All worked and I loved it because I could do a ping test. Now torque pro connects with the mx but won’t diagnose. I get error code saying ecu not supported etc.. Well, this isn’t true because it was working before. PLease help cause I love the app. thanks Note, other apps are working, obdlink and dashpro. thanx

If it was working okay before but not
now… your adapter may be suspect
but not likely if the other apps are
working.

Is your vehicle profile set to use the
correct protocol for your vehicle?

Are you using the latest version of Torque Pro
from Google Play?

(Just another Torque Pro user).

Looking under the Adapter Status icon
functions will show how far Torque is
getting with trying to connect.

Remember the adapter will only connect
with one device at a time so make sure
no other apps/devices are connected
to it.

Connecting is the responsibility of the
adapter and setting the protocol. So
if your adapter is paired correctly to
your phone and the correct protocol
is in use then I would look for bent
pins in the DLC connector, review Torque
settings to make sure they are correct.
Things like BT/Wifi settings, correct adapter
is specified if you have more than one in
use, and alternate OBD headers setting in the
vehicle profile advance settings.
