• HW Installation Support
  • SWC button no response after sleep

Abogrhen Sorry for being a bit harsh but you're not the first one that post without the device info. And this thing starts to be a habit among members. Some people don't understand that without "device info", the devs cannot help that much.

What is your vehicle model and is the SWC signal wire connected correctly?

    dudu-lai hi
    Hyundai elantra 2010

    Yes it is correct also i have tried it on my older unit and it was fine

      6 days later

      Abogrhen Is there a difference between restarting the DUDU7 or restarting the car when the SWC button does not work

        dudu-lai hi
        No difference

        So i notice that if you programed the key and restart the unit directly or
        restart the car it self the same thing
        The button stop responding

          Abogrhen
          When the buttons are out of order, does the number of each button change after re-learning compared to the last time? Normally, the number is fixed no matter how many times it is learned, but if it changes, it may be due to a change in the resistance of the steering wheel.

            dudu-lai
            No
            They stay the same
            Also the resistance numbers
            Doesn't change


              Abogrhen This has never happened before, assuming it's a software issue and the learn icon doesn't disappear but doesn't work when pressed. Assuming the SWC button doesn't work, but nothing was done, just relearned and then worked again, being able to learn on proves the cable connection is fine, confusing me.

                Yah
                on thing i can think of
                Is that some services that handled this goes to sleep and don't work again

                But on "canbus" cars the canbus wake the service up so that doesn't happen to them

                  Abogrhen Settings - Automotive - Startup Settings - Set to off when engine is off, is this ok?

                    dudu-lai
                    This is the current setup
                    Should i try to set it as shutdown ?

                    I tried the shutdown setting
                    But no difference

                    Try using a CANBUS bus box to see if that solves the problem.

                      dudu-lai
                      Thanks for the suggestion
                      But as far as I know
                      There is no canbus available for my car
                      (Hyundai elantra 2010 )

                      As it older model with standard ISO connection as the car came with JVC unit from factory and later on upgrade it to Kenwood unit
                      Before moving to android head unit
                      And all of them worked with SWC button

                      And as the buttons work fine when programmed it's clearly a software bug

                      Any way i have ordered my self the dudu Bluetooth remote to solve the problem for now

                      But i hope that you can flag this problem and try to get into it later on

                      11 days later

                      hy, im driving also hyundai ix35, 2012 (year of production - car model without CANBUS), only cable, i have question regarding head lights ON/OFF, doors ON/OFF (it shows on car command displey/desktop)...does lights on/off, door on/off only works with CNBUS, or it support some car models without CANBUS?? my swc works solid, only sometimes it dont show volume up/down graphic on screen, and and some buttons are slow to response but i think it is related to usage during years

                        It is not possible that your car doesn' t have CANbus.
                        CANbus is one of five protocols in OBD-II
                        2001: The European Union makes EOBD mandatory for all gasoline (petrol) vehicles sold in the European Union, starting in MY2001 (see European emission standards Directive 98/69/EC).
                        2003: The European Union makes EOBD mandatory for all diesel vehicles sold in the European Union
                        2008: All cars sold in the United States are required to use the ISO 15765-4 signaling standard (a variant of the Controller Area Network (CAN) bus).

                        See also ISO 15765-4.3:2001 “Road Vehicles-Diagnostics on Controller Area Network (CAN)—Part 4: Requirements for emission-related systems”, (December 14, 2001)

                        So, by law, worldwide, every car has to have CANbus for control of emissions.
                        Actually your car does not have "a" canbus, Most cars have 5-9 CANbuses connected to the several systems in the car.

                        What you proablably mean is that you ordered a unit without CANbus decoder.

                          Hi although you're replying to @obelix80
                          Your are correct that all cars have obd2 protocol connection nowadays

                          What we mean here is newer cars have a connection to the car radio that make it (smart) by getting some information from other systems

                          Like if the door is open or if the head light is turned on and many more
                          So need to decode the signal
                          So you use a canbus decoder

                          Unfortunately some economy older
                          Japanese - Korean cars think 2015 and older do not have that

                          And use simple ISO radio connections that not communicating with car at this level

                          My car came originally with an aftermarket style one din stereo

                            OK. I understand.
                            Your car simply does not have the CANbus Hi Lo wires (and some more) connected into the ISO plug, or si it seems.

                            Is it not possible via Hyundai or some other source to get an extended ISO plug?

                              I can't comment about the other guy

                              But for me
                              Adapter harness is pluged in
                              and have the prober connection

                              And it communicating with head unit

                              Also i have used an older unit and it works fine there

                              My only problem with this unit
                              Is after programming the key for the steering wheel
                              They work fine
                              until reboot or restart or deep sleep
                              They stop working

                              For now i have installed a Bluetooth remote control on the steering wheel that i got from dudu

                              I hope they can fix the issue
