    Resolved fault of the emergency indicators

    When I bought this instrument panel as a replacement, I was aware that it had a fault.

    The fault was that whenever the ignition key was turned, the four indicators lit at the same time, there was no way to cancel them with the button that is embedded in the same instrument panel, they could only be canceled by placing the signals of turn left or right. The button embedded in the instrument panel itself did not work.

    So since the instrument panel was only a replacement I was not worried, and I had it installed on the work table, but it was a nuisance every time the ignition was turned on, since all four turn signal lights would flash again.

    To take pictures of the Can-Bus, I removed the instrument panel from the workbench and since I had the instrument panel out, I set out to repair it and locate the faulty component.

    It has been difficult for me to locate the fault, without an electronic diagram it is very complicated. But experience is a degree ...

    The problem was a faulty capacitor SMD that is just before entering the microprocessor, before the capacitor there is a resistor, which, when the ignition key is turned on, sends a signal of 5 volts and later sends a pulse to the microprocessor and the capacitor avoids damaging the microprocessor with a voltage of 5 volts.

    I leave the photos in case someone had the same problem and with knowledge of someone brave and capable, can solve it.





    I have marked with a red circle where the condenser was, it is so small that when I removed it it has fallen to the ground and I have not been able to find it.


    Here already with SMD capacitor in place.


    Now it works perfectly, when placing the ignition key the four fault lights no longer flash. Also now if the button embedded in the same instrument panel works.

    Yes, well done digital and thanks for sharing.

    It's this sort of electronic thing that concerns most of us 'old school' home mechanics I'd guess, once a vehicle becomes a few years old, the cost of having to buy such an whole unit from a main dealer probably wouldn't be worth it, most owners would just move on to another vehicle.

    Indeed, I admire a good forum and I am in favor of sharing in the forums the information that is possible and the administrators leave you.

    In a forum, you will always have the information available, which nowadays people use WhatsApps a lot and no information is stored there.
