Summary of change:
notes for [https://shop.vems.hu/catalog/vems-motronic55-p-122.html VEMS Audi AAN] (with JPT/55 connector). * See VemsAudiAan * do NOT forget to create your page, see MembersPage ** this is very important '''when deviating from factory (VR/auditrigger) setup ** it is even more important if the wrong part was ordered (request "AAN ECU with HALL/HALL trigger" in the order comment: without this, the factory ** even more important if ordered multiple ECUs with the wrong type (factory VR/auditrigger instead of requesting HALL / HALL) ** it is super-important if any complications appear (eg. no complete success with the first home-converted device). For HALL / HALL sensor, a supply voltage is needed. '''+5V supply is included on JPT55/pin48.''' * This was requested by customers applying custom solution: HALL / HALL trigger. Those who order HALL / HALL type (because using nonstandard trigger setup) usually know what they are doing. * This way +5V can be easily made available for the HALL sensor (but care might be needed, to not plug in VR sensor, or short to GND) * [http://vems.hu/download/v3/Motronic55/Audi/v3.9AAN/aan_typical_EC10_pinout_hall_hall.doc paper] is included with HALL/HALL device that explicitely mentions this +5V * see [http://vems.hu/download/v3/Motronic55/Audi/v3.9AAN/ for some AAN v3.9 illustrations] that might be of help to get some idea about the differences of standard VR/auditrigger setup, and when "AAN ECU with HALL/HALL trigger" requested ** keep in mind that any device is customized from base-board (not first making VR/Auditrigger and than converting to HALL / HALL). ** eg. SJ7 must be closed for sectrig auditrigger, not for HALL (so HALL / HALL type didn't mention SJ7 originally because it can be left open: needs to remove solderblob if converting from VR/Auditrigger) ** make sure to download latest version (eg. "SJ7 open" was added to HALL / HALL) '''v3.9 AAN HALL / HALL''' : http://vems.hu/download/v3/Motronic55/Audi/v3.9AAN/trigger_bottom_hall.jpg http://vems.hu/download/v3/Motronic55/Audi/v3.9AAN/assembled-Bottom_HallHall.jpg ---- In case of any problem (or suspected problem), follow * [https://shop.vems.hu/catalog/refer_to_thematical_page.php Tech request] * eg. specify intent (eg. "I accidentally ordered the standard type with factory trigger, and want to convert device srl/... from oid/...) from ... to ... * detail what modifications made (yes, step-by-step, even if repeating some docs) * measurement results (eg at JPT55 and sensor pins) * photo of result * triggerlog (with annotation, eg. I think sectrig does not appear) ** for convenience, you can do it on this page for now. We'll clean it up later If a conversion is not success, do NOT duplicate. ---- '''Conversion notes, measurements, photos''' ... add your notes... [http://vems.hu/files/MembersPage/LabeFahrzeugtechnik/v3.9AAN_HALL_HALL/ photos from customer, with partial conversion] - important areas highlighted Since than: * R30=4k7 (assumed to be applied, please confirm) * remove SJ7 (done on the photo) * '''remove R248''' - remove some hotmelt to access * '''install R48''' * ... anything else done ? measured ? Note: * v3=10585 '''originally only this was mentioned to be converted''' ** although not reported any other device serialnr, suspected that v3=10505 and v3=10519 also attempted ? ** these (AAN with srl less than 10520) might not have JP22
