  • Citroen C5 2.0 HPI (2001) no voltage on pin 16

    Hello

    I just brought the ELMSCAN 5.
    I own a Citroen C5 2.0 HPI from 2001.
    In the OBD-2 specs it states that: pin 16 has 12V but no voltage there at all!
    On “service.citroen.com” it’s stated that 12V is on pin 1 (when the ignition key is turn on)
    I found this to be true and thinks I need to make a new cable for the ELMSCAN 5 in order to get it to work.
    Does anyone have any experience with the C5 and OBD-2?

    Best regards

    Carsten

    Take 12V from cigar lighter plug

    Hello

    I made a adaptor to put between the ELMSCAN5 and the OBD-cable.
    Gnd, signal-gnd, K-line is passed on but pin 9 (12v) is taken from cigar lighter plug.
    Now the interface powers up and I can "talk" to the car.

    Yhaa!
