  • Vauxhall canbus controls

    Hi,
    i have a elm327 and i was just wondering if i could listen out for steering wheel control commands using the standard OBD2 port.

    im not sure if the steering wheel controls are on a seportate bus or not?
    can somebody point me in the right direction

    regards,
    Mark

    Steering wheel controls are on another can-bus, not on the powertrain one (pin 6&14) your elm connects to. It has a different speed also.

        I don't know if Vauxhall uses the GMLAN protocol. If it does, you may want to look at this project, since they managed to control the stereo and required only changing a single pin and shorting 2 others:

          the CAN232 also comes as a board. it would be nice if the firefly also came as a board.
          i carnt be the only person with CAN steering wheel controls/ displays thats got a car pc.

          it would be nice to bulk buy these!
