we dont need transistor circuit anymore, just add a switch between pin 20 of ft232bm/bl and ground (pin 4 or 5 of obd2 connector in interface, or pin 17 in ft232bm/bl chip, or black wire of usb connector in interface, etc. I think for cars with 20pin connectors only solution is: In adapters from ebay, it seems round side can be opened but not obd2 side, so it is not possible to solder a wire between them. If so, what about cars with round 20 pin connectors? in 16pin-to-20pin adapters, pin1 of obd2 side is not connected to any pin of round side so that it will never be powered, so car key memory is not supported?Įdit: according to, pin 16 in round bmw connector is +12v ignition but it is not taken into account in obd2-to-bwm adapter, so i suppose that for car key memory we should also solder a copper wire from pin 16 of bmw side to pin 1 of obd2 sideīMW OBD II vehicle diagnostic connector pinout and wiring ()
I suppose that in car key memory process, inpa must detect in certain moment that key is turned to off position but with interface still plugged to car, showing battery black dot and ignition white dot. In your picture both dots are black without connecting interface to car ?Įdit: sure, because your interface got no transistor, so it doesnt depends on pin1 to make ignition dot blackįor car key memory we must do next circuit but it says pin 1 is ignition (instead of +12v by pin16) so i understand that in bmw cars pin 1 gets powered when turning the key to ignition positionĮdit: according to, pin 1 is +12v (power) so i asume it only got power when key is turned to ignition position, BMW OBD-II diagnostic interface pinout and wiring () Will ignition dot turn black when connecting interface to car so that pin1 is also powered? or what is the problem?Įdit: exactly! it works! i have powered pin 1 of interface and i get both black dots! I have conected interface to 220v/12v ac/dc power adapter (+12v to pin 16 and gnd to pin4+5) but i get the same results
I have modded my vag com kkl interface with ft232BL (not RL) as you said and installed inpa (loader 4.4.7, bmw group rectification programs uk v3.01) but when i connect interface to computer and start inpa (_.ipo) i only get battery on = black dot (ignition is off = white dot)
#Navcoder full version software
Now you can use navcoder or other i-bus software You could search in wds for your car wires you will need 12v, gnd, and i-bus wich is usually a white and yellow cable OBD2 connector pin 4 or 5 to negative (gnd) cableĪnyway just plug it into your obd2 and start navcoder or connect it to your cd changer or radio, whatever. OBD2 connector pin 16 to 12v Positive cable With this in mind, connect three cables as follows The Resler interface works with 4 outputs (ibus, 12v, gnd and NTSC) NTSC signal is used to the camera and as we don't have the chip for its management, just forget about it. It work's with inpa,dis,sss, carsoft 6.1.4 () and navcoder alsoįor the navcoder you usually need a RESLER interface but you don't really need it Note: This interface supports cars from 96/98 to March 2007 In case anyone wants to do it in the FT232RL here are the outputs of the chip. Note: if you don't do this circuit you will not be able to do CAR KEY MEMORY So you need to solder pins 17,18 and 20 of the FTDI chip (this applies to the BL and BM) like thisīut if we want some REAL battery and ingnition detect, we must do this circuit If your vagcom comes with ft232bm/bl chips, don't worry you only need to do some work We need to invert RI # and DSR # signals to fool the detection of battery and ignition, in order to be able to encode.Ĭheck your I / O Controls settings, them must be like this: Prog 3.5" () to modify the programming of the eeprom FT232RL,

Now we need to adjust the serial port, press the Windows key and Pause (both), then follow these images (sorry my XP is in spanish language)ĥ# Download the "M.
#Navcoder full version install
I preferred to catch it on ebay, because it was more comfortable and cheaper than going to catch the pieces out there, also for those wishing to DIY, I leave the chart with specific connections.ģ# Open your vagcom and solder obd2 pins 7 and 8, which are the K lines, otherwise you will not be able to access to all modules from the carĤ# If you have buyed vagcom with ftdi 232 rl, for the software mod, you will need this driver "CDM WHQL certified" (), so unpack it, connect the cable, and install all with this driver. why? well basically because that chip support software mods.Ģ# As my 530d do not have odb2 connector, I order a cable adapter from obd2 to 20 pin bmw, ebay seller is ( Car.Doctor ) another 8 ***8364 + shipping. Hi guys, first of all, this isn't new but all info is spread over there and it's a bit difficult to get all info together so i made this postġ# buy some Vagcom cable KKL 409.1, just 8 ***8364 + shipping from ebay, ask the seller if it has the chip FT232RL.
