    Default LKM pin details

    valid for LKM-L and LKM-B.

    1 High Beam stalk at steering wheel
    2 terminal 30 (continious power)
    3 switch low beam/dip light
    4 data to CCM = check control module
    5 data to CCM = check control module
    6 F1 terminal R, IC supply
    7 from k7 P2 - tail light right

    8 tail light right
    9 tail light left
    10 parking light right
    11 parking light left
    12 from brake light switch

    13 brake light left
    14 switch licence plate light on
    15 3rd brake light
    16 fog light front left
    17 F7 15A, terminal 30
    18 fog light switch
    19 rear fog light switch

    20 high beam via fuse F13, F14
    21 low beam left F10
    22 low beam right F11
    23 check via CCM + CC + OBC (check control module-check control-on board computer)
    24 ground
    25 data to CCM

    26 from K7P6 tail light left
    27 from K7P9 parking light right
    28 from K7P5 parking light left
    29 brake light right

    30 licence plate right
    31 licence plate left
    32 fog light right, front
    33 fog light right, rear
    34 fog light left, rear
    35 F8 15A for rear fog light

    Note: this is the ECE/EU version, some pins might be missing in other versions. But the set - up will be the same. So for the US LKM probably the pins for rear fog light might not be there respect. not connected internally.
    Depending on year of production and the makers of the LKM the internal parts look different, but the pins are always for the same function.

    so.... no any idea on how to modify the LKM so it doesnt check the low beam continuity?

    Inside the LKM's look quite different, so it is different and depends which one is the maker.
    Here for example a LOEWE LKM, This was modified to omit the message in case of Xenon use.
    The pic with the enlarged photo shows encircled the modification

    If you cannot look at the pics, maybe you first have to register on 7-forum.com
    There are also instructions on the Japanese board how to modify it, but it always depends on which maker the LKM is from.
