    computer diagnostic port

    Yep, an OBD II port to be specific. (OBD = on board diagnostic)

    If you look up "obd ii wireless ELM327" on eBay, you'll get a load of cheap bluetooth readers that can plug into it.

    Then, if you've an Android smart phone, you could run the Torque Android app to read all sorts of interesting engine diagnostic codes and readouts from it.

    EOBD to be exact.


  • Closed Accounts Posts: 8,223 ✭✭✭Nissan doctor


    EOBD and OBDII are both names for the same thing.

    One is the US designation and the other is the European regulated version of the same thing.

    oh, I know about this port but I always though that in order to access it you need to take some kind of car panel off under steering wheel, unplug some kind of wires and plug in the reader, damn that's why I hear people saying that it's possible to break into car and do something using that port.

    Mostly pub talk TBH.


    EOBD/OBDII standardisation regs mean that the diagnostic ports have to be within a certain distance of the steering wheel in certain positions(can't be hidden or require any special tools/procedures to get to) so on most cars they are just mounted under the dash or behind a small over/panel which will normally say OBD on it.

    oh, alright thanks that explains a lot so. So technically is it possible to override/take controlls of car over that port?

    Like remotely drive the car? That's a right one to use when youre late to dinner with the missus, 'some frcker drove my car to the pub, would have been rude of me to just leave then'

    No, you cannot start the car or anything like that. The ignition has to be on or the engine running already before the OBD port becomes active and even then, although, with decent equipment, you can activate/test certain components, you are mostly just reading signals/data from the ECU.

    I meant stuff like alarm or something, or avoid immobilizer. I mean electronics controlls obviously you can;'t drive car from it, it's not a bat mobile afterall :D


  • Closed Accounts Posts: 309 ✭✭haulagebasher


    You've been watching Gone in 60 Seconds too much mate. Even with wireless connection, you'd still need the key in the ignition to do anything. Even then the most you could do is test stuff like brake actuators and stuff. For fiddling stuff like windows or brake systems you'd need manufacturere specific software anyway.Besides, the EOBD/OBD II standard only controls engine and emissions systems anyway. Stuff like alarms and immobilizers are not covered by EOBD and are manufacturer specific functions. Relax

    Alarms/immobilsers etc can be deactivated on certain cars with certain equipment, but like I said, in order to access the system, the ignition has to be on, which needs the signal from the key anyway on modern cars.

    I have no idea what gone is 60 seconds is and I've never watched it, I just read threads here on boards and often people reference this port for break in.


  • Closed Accounts Posts: 309 ✭✭haulagebasher


    even if it were readily possible, who would be bothered doing it to a bloody corsa?

    No and No,

    And No your corsa is not desirable apologies if this seems harsh, but no.

    I know about my car, I bet no one would take it even if it was on street there parked completely open and keys in ignition barely anyone would want it :D
    I am just finding out for a personal knowledge

    All functions, standardised and manufacturer specific are read/operated through the one OBD port.

    I know that, but I'm just saying that a more basic setup scantool will only read and do functions covered by EOBD and that one that does manufacturer specific stuff is needed for non-eobd functions, usually such a set up will cost $$$$.
