Anyone know why when i leave my bluetooth adapter in my ODBII port over night, that when i get in and start my car the next morning, without starting Torque Pro, my dash lights up like a Christmas tree? ABS light on, CEL light on, traction control light on, e-brake light on.
It's weird. Goes away after i shut my car off, remove the adapter then restart the car.
This happens on some Fiat cars when using cheap clone adapters.
I believe they send trash to the CANbus and the dashboard node is very sensitive. On some tests that i have performed, in this case the dash loses connectivity with the other CAN nodes, and this is the reason why the lights become crazy.
You need to test a different adapter and replace the current one.
