Mapepala a OBD-II DTC

Kutaya Kulumikizana Ndi Telematic Control Module

Kodi izi zikutanthauzanji?

Imeneyi ndi njira yodziwika bwino yolumikizira matenda yomwe imagwiritsidwa ntchito pazipangidwe zambiri za mitundu ya OBD-II.

Makhalidwewa amatanthauza kuti telematics control module (TCM) ndi ma module ena oyendetsa pagalimoto samalumikizana. Ma circry omwe amagwiritsidwa ntchito kwambiri kulumikizana amadziwika kuti Controller Area Bus kulumikizana, kapena basi basi ya CAN.

Ma module amalumikizana kudzera pa netiweki, monga netiweki yomwe muli nayo kunyumba kapena kuntchito. Opanga magalimoto amagwiritsa ntchito ma network angapo. Chaka cha 2004 chisanafike, njira zolankhulirana zofala kwambiri (zosakwanira) zinali njira yolankhulirana, kapena SCI; SAE J1850 kapena PCI basi; ndi Chrysler Collision Detection, kapena CCD. Njira yofala kwambiri yomwe idagwiritsidwa ntchito pambuyo pa 2004 imadziwika kuti Controller Area Network kulumikizana, kapena basi basi ya CAN (yomwe imagwiritsidwanso ntchito mpaka 2004 pagawo laling'ono lamagalimoto). Popanda basi iyi ya CAN, ma module oyendetsa sangathe kulumikizana ndipo chida chanu chowunikira chitha kulandira kapena kusalandira chidziwitso kuchokera mgalimoto, kutengera dera lomwe lakhudzidwa.

Ma module a telematics control (TCM) nthawi zambiri amakhala kuseri kwa dashboard, nthawi zambiri amakhala pakatikati pa galimotoyo. Ikupezekanso kumbuyo kwa galimotoyo mu thunthu kapena chipinda chosungira kumbuyo. Amalandira zolowetsa kuchokera kuma sensa osiyanasiyana, zina zomwe zimalumikizidwa mwachindunji, ndipo zambiri zimafalikira pamayendedwe olumikizirana mabasi kuchokera ku powertrain control module (PCM). Zolowererazi zimalola gawolo kuti liwonetsetse njira yolondola powerengera momwe galimoto ilili ndikutumiza zidziwitsozo pa basi ya data pagawo loyendetsa kapena pagulu lazida / chiwonetsero chachikulu.

Njira zothetsera mavuto zimatha kusiyanasiyana kutengera wopanga, mtundu wa njira yolumikizirana, kuchuluka kwa mawaya, ndi mitundu ya mawaya olumikizirana.

Kuuma kwa code ndi zizindikilo

Kukula kwake pakadali pano kumatha kukhala kovuta ngati TCM itumiza zolakwika pa gawo lowonetsera / makina, potero zimapereka chidziwitso cholakwika chazoyenda.

Zizindikiro za nambala ya U0198 itha kuphatikiza:

• TCM imapereka chidziwitso / mawu / mwina mawonekedwe opanda kanthu
• TCM siyiyatsa / sigwira ntchito

zifukwa

Nthawi zambiri chifukwa chokhazikitsa nambala iyi ndi:

• Tsegulani pa CAN basi + kapena - dera
• Mfupi mpaka pansi kapena pansi pamayendedwe aliwonse a CAN
• Palibe mphamvu kapena nthaka ku TCM
• Nthawi zambiri - gawo lowongolera ndilolakwika

Njira zowunikira ndikukonzanso

Malo abwino kuyamba ndi ZONSE zamagetsi ndikuwona Technical Service Bulletins (TSB) pagalimoto yanu. Vuto lomwe mukukumana nalo lingadziwike kwa ena kumunda. Kukonzekera kodziwika kumatha kukhala kutulutsidwa ndi wopanga ndipo kumatha kukupulumutsirani nthawi ndi ndalama panthawi yozindikira.

Zimaganiziridwa kuti owerengera nambala yamakalata amapezeka pano, popeza mwina mutha kupeza manambalawa mpaka pano. Onani ngati pali ma DTC ena aliwonse okhudzana ndi kulumikizana kwa basi kapena batri / poyatsira. Ngati ndi choncho, muyenera kuwazindikira koyamba, popeza misdiagnosis imadziwika ngati mungapeze nambala ya U0198 musanapezeke nambala iliyonse yazomwe zatsimikiziridwa ndikuwongolera.

Ngati khodi yokhayo yomwe mumapeza kuchokera kumagawo ena ndi U0198, yesani kupeza TCM. Ngati mutha kupeza ma code kuchokera ku TCM, ndiye kuti code U0198 mwina ndi yapakatikati kapena kukumbukira kukumbukira. Ngati TCM siyingapezeke, ndiye kuti nambala ya U0198 yomwe ma module ena akhazikitsidwa akugwira ntchito ndipo vuto lilipo kale.

Kulephera kofala kwambiri ndi kulephera kwa dera komwe kumabweretsa kutaya mphamvu kapena kutsika kwa module ya telematics.

Onani mafyuzi onse omwe amapereka TCM pagalimoto iyi. Onani zifukwa zonse za TCM. Pezani mfundo zolumikizira pagalimoto ndipo onetsetsani kuti malumikizowo ndi oyera komanso otetezeka. Ngati ndi kotheka, chotsani, tengani burashi yaying'ono yolumikizira waya ndi yankho la soda / madzi ndikutsuka chilichonse, cholumikizira komanso malo omwe amalumikizana.

Ngati kukonzedwa kulikonse kwachitika, chotsani ma DTCs kuchokera pamitundu iliyonse yomwe imayika chikumbukiro ndikuwona ngati mutha kulumikizana ndi TCM. Ngati kulumikizana ndi TCM kuchira, vutoli mwina ndi fuse / kulumikizana.

Ngati nambala yanu ibwerera kapena kulumikizana ndi gawoli likulephera, pezani kulumikizana kwa mabasi a CAN pagalimoto yanu, makamaka cholumikizira cha TCM, chomwe nthawi zambiri chimakhala kuseri kwa dashboard, nthawi zambiri pakati pa galimotoyo. amathanso kupezeka kumbuyo kwa galimoto mu thunthu kapena chipinda chosungira kumbuyo. Chotsani chingwe choyipa cha batri musanachotse cholumikizira pa TCM. Mukazindikira, yang'anani zowonera zolumikizira ndi zingwe. Fufuzani zokopa, scuffs, mawaya owonekera, mabala owotchera, kapena pulasitiki wosungunuka.

Chotsani zolumikizira ndikuyang'anitsitsa malo (zitsulo) mkati mwa zolumikizira. Onani ngati akuwoneka owotcha kapena ali ndi utoto wobiriwira wosonyeza dzimbiri. Ngati mukufuna kuyeretsa malo, gwiritsani ntchito zotsukira zamagetsi ndi burashi ya pulasitiki. Lolani kuti muumitse ndikupaka mafuta amagetsi pomwe matomata amakhudza.

Chitani macheke ochepa awa musanayambe kulumikiza zolumikizira ku TCM. Mudzafunika kupeza digito volt/ohmmeter (DVOM). Onetsetsani kuti TCM ili ndi mphamvu ndi nthaka. Pezani chithunzi cha mawaya ndikuzindikira komwe mphamvu yayikulu ndi zinthu zapansi zimalowera mu TCM. Lumikizani batire musanapitirize ndi TCM yoyimitsidwa. Lumikizani chowongolera chofiyira cha voltmeter yanu ku B+ iliyonse (voltage ya batri) yomwe imalowa mu cholumikizira cha TCM, ndikuwongolera kwakuda kwa voltmeter yanu pamalo abwino (ngati simukutsimikiza, batire imagwira ntchito nthawi zonse). Muyenera kuwona kuchuluka kwa batire. Onetsetsani kuti muli ndi chifukwa chabwino. Lumikizani chowongolera chofiira cha voltmeter ku batri yabwino (B+) ndi chowongolera chakuda kudera lililonse lapansi. Apanso, muyenera kuwona mphamvu ya batri nthawi iliyonse mukalumikiza. Ngati sichoncho, konzani mphamvu kapena dera lapansi.

Kenako yang'anani zigawo ziwiri zoyankhulirana. Pezani CAN C+ (kapena HSCAN+) ndi CAN C- (kapena HSCAN - dera). Ndi waya wakuda wa voltmeter wolumikizidwa ku nthaka yabwino, gwirizanitsani waya wofiira ku CAN C+. Ndi kiyi yoyatsidwa ndi injini yozimitsa, muyenera kuwona pafupifupi 2.6 volts ndikusinthasintha pang'ono. Kenako gwirizanitsani waya wofiira wa voltmeter ku CAN C- dera. Muyenera kuwona pafupifupi 2.4 volts ndikusinthasintha pang'ono. Opanga ena amasonyeza CAN C- pafupifupi 5V ndi kiyi oscillating ndi injini kuzimitsa. Yang'anani zomwe wopanga wanu akufuna.

Ngati mayesero onse akudutsa ndipo kuyankhulana sikungatheke, kapena simunathe kuchotsa DTC U0198, chinthu chokhacho chomwe chingachitike ndikupempha thandizo kwa katswiri wodziwa zamagalimoto ophunzitsidwa bwino, chifukwa izi zidzalozera ku TCM yolakwika. Ambiri mwa ma TCM awa ayenera kukonzedwa kapena kusinthidwa kuti ayike bwino galimotoyo.

Mukufuna thandizo lina ndi nambala ya U0198?

Ngati mukufunabe thandizo ndi DTC U0198, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
