MadeInJapan Posted August 26, 2006 Author Report Share Posted August 26, 2006 That's what I suspected, 3 wires, one +12V, one -12V and which pin does the other one go to?My tool does read and reset the ECU so I am fairly sure that once I know where the 3rd one isI can reset the service lamp. That's what I'm trying to find out here. There are many more pinsand only 3 are identified (excluding the +/- terminals.) Unless someone with more knowledgecan add to this discussion I'm convinced that at least on the 850 series, if not V70Is as well thatthe under the hood diags were simply rewired/relocated to the RS232 plug under the coin holder.My tool gives the same blink-code sequences as with the 95 and previous owner friendly system.I'm not sure if it's going to be as easy as you say. Like I mentioned in one of the above posts, there are only 3 pins used, but there's also a memory chip (ATMEL AT89S52-24JI, an 8bit microconroller with 8K bytes of flash and 256K of RAM memory) inside the Draper and some other small electronics. It appears that some type of "flashing" from that memory piece to the ECU has to go on to clear this code. Here is a picture of the insides of the Draper. Below it, please also find the pin configuration marked with red spots as to which pins are used:Further, I found this from the ATMEL company...very specific specs and info about the chip used in the Draper: http://www.atmel.com/dyn/products/product_...mp;part_id=1918 Link to comment Share on other sites More sharing options...
MadeInJapan Posted August 28, 2006 Author Report Share Posted August 28, 2006 OKay, I ended this attempt at a group buy...not enough interest. If you still want the Draper Tool for a substantial savings ($66-67 to your door), then IM me or email me. Link to comment Share on other sites More sharing options...
