    VW Crafter metal tin lack of interior lighting and cargo space.
    There is a constant weight in the cabin on the lamp, the lack of this after opening the door, the counter reacts to the opening of the door.
    Please help

    There are two mistakes:

    Address B4: Central electronic assembly
    Item designation SW: 9069027500 HW: 9069011400
    Service code: WSC 00000 000 00000
    ASAM dataset: 33,548
    ROD: CRFT_EZE_33_548.rod (*)
    VCID: 060963C5B9486F71D3-8052

    2 - number of errors found. Here they are:
    9042 - Front interior lighting (W1): short to positive
    Test completed - Active / saved
    90B5 - Fault 90B5: FNrSgDefekt_ShortCircCount (not supported)
    Test completed - Active / saved

    As you can see from the errors you have a short circuit with a plus (+). You probably need to pull this plastic (housing) out of the headliner and check if there is a short circuit, similarly in the cargo area. Fuses would also be useful to peek before and after these attempts.

    Light bulbs were a problem in the cargo space, but it is still "dark" in the cabin.
    All fuses checked.
    The lamp and bulb in the cabin are functional.
    There are three wires from the lamp:
    - permanent +12
    - constant mass
    - mass after opening the door or pressing "open" on the remote control.
    The beam from the lamp to the "SAM" checked.
    Errors are still the same, what do they mean? is the "SAM" module to be replaced?

    If you replace ordinary bulbs for LEDs (the cheapest), you'll always have errors because you have attached detection of defective bulbs. I don't understand your statement very much. If they go from a functional bulb in the cab, then release from the battery through the fuse directly to these bulbs and after the problem.

    Did I write anything about leds?
    Why should I give additional "permanent" power supply through a fuse, if I have it?
    If you don't know what the "SAM" module is, you don't know what I'm writing about.

    Set the lamp switch to the constant light position and check with the meter whether there is a short circuit, if not the same for substitution and there is nothing to debate. I am writing about checking in this way because you did not specify what measurements you made and whether it was not just a circuit continuity test.

    I unplugged the plug from "SAM" which has three wires:
    +12 - goes to the front and back lights
    front lamp weight
    rear lamp weight

    I gave the power supply from the rectifier there, and the lamp works, which indicates that the "SAM" module is damaged.
    I found a translation of the errors in the twin MB Sprinter 906:

    (9042) Front interior light-The function is implausible.
    (90B5) N10 (SAM control unit) -Status of output stage Implausible value.

    For the sake of peace, replace the light bulb so that it does not turn out that it simply draws too much current, which SAM interprets as a short circuit and how to change the module. You can still dismantle the current one and look at the current control system in this circuit because the increased resistance in the shunt circuit can cause such results but is it worth it? It's up to you :)

    As the first I changed the bulb, I also connected the indicator and meter in place of the bulb, with no effect.
    Can this module be replaced without additional operations? assuming that I can get the same numbers.

    For the diagnosis of damage, you can replace, if you want to replace it would suit to code the equipment.

    I have the same problem with the same module. Adjusting the electric mirrors do you work? Next week I will try to fix it

    Unfortunately, the customer had to take the car, I think I will look into it, car almost on the road ... I will definitely write. Tell me if the mirror adjustment works for you

    I have mirrors control.
    I have this symptom:
    lighting does not work automatically: i.e. when I release the light with a button it comes on, and something else: on the dashboard after a while the yellow light turns on - as if a light bulb burned somewhere in the car ... but I don't know how check because there are a lot of them ...

    Hello
    I have exactly the same problem as my friend Wacek or maybe someone found a solution.

    Hello!
    I have the same problem with the crafter with the interior lights that do not work when the doors open. they only work when I manually turn on the button.
    can you please tell me how you solved this problem?
    thank you
