OBD power draw?
Hello everybody,
I just purchased an OBD2 bluetooth dongle, which has an on/off switch on it. Can I be 100% sure that there will not be any power draw at all as long as the switch is on the "off" position? Best regards, Alex |

I've had my OBDLink MX in two cars It doesn't have an on/off switch per se, but goes into sleep mode when the car is turned off. I've had no problems with it.

You can't be sure of anything, but if it actually has a switch I would expect it to work. What brand/model is this? |

I wonder if this ties into the mystery of the BRZ battery drainage. Perhaps the waking scanner is not the cause but rather a symptom of unwanted CAN bus activity.

I would prefer a manual toggle. I had looked for one when I bought these, but nobody had one. Now I'm going shopping again. |

I haven't tested it in my FRS, but in my Miata the OBD would come out of sleep mode if I even touched the car, and that was without keyless ignition. I could tell by going in the garage at night. I could see it light up when it activated. For all I know, it might not be sleeping in the FRS because I drive it almost every day.
