Post Connects/disconnects from ECU
on: September 14, 2019 (GMT)


I have a MK3.5 Focus ST.

I have the Torque Pro app installed and 2 ELM bluetooth adapters. I have a problem. It connects to ECU fine, drive for a few mins then suddenly disconnect from the ECU (still connected through BT)

Only way i can get it to connect again is to turn the ignition off and on again. Something is causing this to happen as i don’t recall it doing this before.

Any ideas?

Things i have tried:

another ELM adapter

disconnect battery

Flashed stock map back on and back to remap

factory reset my phone and app

Downgraded to older Torque pro

Forced Protocol (can’t remember which one that connects)

Turned off Bluetooth on the car

You might check the voltage/condition of
your OBD connector. (DLC).
