Ukuhlonza Izimbangela Zekhodi Yephutha P068A

Njengamakhodi amaningi, isiqalo esihle sokuxilonga le khodi ukuhlola ne-TSB (Imininingwane Yesevisi Yobuchwepheshe) yemoto ethile. Inkinga ingaba yinkinga eyaziwayo enesixazululo esaziwayo esinikezwe umenzi.

Thola wonke amakhodi agciniwe futhi umise idatha yozimele ngokuxhuma isithwebuli endaweni yokuxilonga yemoto. Naka lolu lwazi uma kwenzeka inkinga ibonakala ihamba kancane.

Bese usula amakhodi bese uhlola ukushayela imoto (uma kungenzeka) kuze kube yilapho ikhodi isuliwe noma i-PCM ingena kumodi elungile. Uma i-PCM yenza lokhu kokugcina, khona-ke inkinga iphakathi, okusho ukuthi udinga ukulinda kuze kube kubi kakhulu ngaphambi kokuthi usebenzise ukuxilongwa okugcwele. Ngakolunye uhlangothi, uma ikhodi ENGEKHO ukusethwa kabusha futhi kungekho ukushayela, qhubeka nokusebenzisa imoto njengokujwayelekile.

Xhumana ne-TSB ngekhodi egciniwe, imoto (ukwenza, unyaka, imodeli kanye nenjini) nezimpawu. Lokhu kungase kukusize ekwenzeni ukuxilongwa.

Uma ikhodi ISULA ngokushesha, qhubeka nokuhlola okuphelele kwesistimu yezintambo nesixhumi. Amahhanisi aphukile kufanele alungiswe uma engashintshwa.

Uma izintambo nezixhumi zibukeka zizinhle futhi zisebenza, sebenzisa ulwazi lwemoto ukuze uthole idayagramu yezintambo, amaphinikhodi esixhumi, ukubukwa kwesixhumi, nama-flowcharts okuxilonga. Ngalolu lwazi, qinisekisa ukuthi i-PCM power relay ithola i-voltage yebhethri ngokubheka wonke ama-fuses nama-relay.

Uma i-DC (noma eshintshiwe) i-voltage ingekho kusixhumi esidluliswayo samandla, landelela isekethe elungile ku-fuse noma udlulise ovela kuyo. Lungisa noma shintsha amafuse angasebenzi kahle noma izixhumanisi zamafuse njengoba kudingeka.

Uma i-voltage kanye nomhlabathi wokunikezwayo wokudluliselwa kwamandla kukhona (kuwo wonke amatheminali angakwesokudla), sebenzisa i-DVOM (i-digital volt/ohmmeter) ukuze uhlole izici zokuphuma kwe-relay kumaphini okuxhuma angakwesokudla. Uma i-voltage yesifunda esiphumayo se-relay yamandla ayanele, khona-ke ukudluliselwa okungalungile kungasolwa.

Uma amandla kagesi e-PCM aphumayo engaphakathi kwezicaciso (kuwo wonke amatheminali), hlola amasekhethi okukhiphayo afanele ku-PCM.

Uma isignali kagesi ephumayo edluliswayo itholwa kusixhumi se-PCM, ungase usole ukungasebenzi kahle noma iphutha lohlelo ku-PCM.

Uma ingekho isignali ye-voltage ephumayo edluliselwe kusixhumi se-PCM, inkinga cishe ibangelwa isekethe evulekile.

Ukuze ugweme ukuxilonga okungalungile, ama-fuse kanye nezixhumanisi ze-fuse kufanele zihlolwe ngesekhethi elayishiwe.

Ama-fuse nezixhumanisi ze-fuse kufanele zihlolwe ngesekhethi elayishiwe ukuze kugwenywe ukuxilonga kabi.

Yiziphi izinyathelo zokuxazulula inkinga ze-P068A?

Isikena sokuxilonga kanye ne-digital volt/ohmmeter (DVOM) kuyadingeka ukuze kuhlonzwe ikhodi ye-P068A.

Uzodinga nomthombo wolwazi oluthembekile mayelana nezimoto. Ihlinzeka ngemidwebo yebhulokhi yokuxilonga, imidwebo yezintambo, ubuso bezixhumi, amaphinikhodi wokuxhuma, nezindawo zezingxenye. Uzothola izinqubo kanye nokucaciswa kwezingxenye zokuhlola namasekhethi. Lonke lolu lwazi luzodingeka ukuxilonga ngempumelelo ikhodi ye-P068A.

Xhuma isithwebuli echwebeni lokuxilonga imoto bese uthola wonke amakhodi agciniwe bese uqandisa idatha yozimele. Bhala lolu lwazi njengoba lungasiza uma ikhodi kuvela ukuthi iyisikhawu.

Ngemuva kokurekhoda yonke imininingwane efanele, sula amakhodi bese uhlola ukushayela imoto (uma kungenzeka) kuze kube yilapho ikhodi isuliwe noma i-PCM ingena kumodi yokulungela.

Uma i-PCM ingena kumodi ekulungele, ikhodi izoba ngezikhathi futhi kube nzima kakhulu ukuxilonga. Isimo esiholele ekuphikeleleni kwe-P068A singadinga ukuba sibi kakhulu ngaphambi kokuba kutholakale ukuxilongwa okunembile. Ngakolunye uhlangothi, uma ikhodi ingenakususwa futhi izimpawu zokubamba zingaveli, imoto ingaqhutshwa ngokujwayelekile.

Xhumana nomthombo wolwazi lwemoto yakho ukuthola ama-bulletins ezinsizakalo zobuchwepheshe (ama-TSBs) akhiqiza ikhodi egciniwe, imoto (unyaka, ukwakheka, imodeli nenjini) nezimpawu ezitholakele. Uma uthola i-TSB efanele, ingakunikeza ngemininingwane ewusizo yokuxilonga.

Uma ikhodi ye-P068A isethwa kabusha ngokushesha, bheka izintambo nezixhumi ezihlobene nohlelo. Amabhande aphukile noma angaxhumekile kufanele alungiswe noma ashintshwe njengoba kudingeka.

Uma izintambo nezixhumi zilungile, sebenzisa umthombo wolwazi lwemoto yakho ukuthola imidwebo ehambelanayo yezintambo, ukubukwa kwangaphambi kokuxhuma, izixhumi zokuxhuma, nemidwebo yebhulokhi yokuxilonga.

Lapho usunolwazi oludingayo, hlola wonke amafiyuzi nokudluliswa kohlelo ukuqinisekisa ukuthi amandla webhethri ahlinzekwa kudluliswa kwamandla we-PCM.

Thola amapharamitha wokucisha amandla okudluliselwa kwe-PCM futhi uwasebenzise ezinyathelweni zokuxilonga ezilandelayo.

Uma kungekho-voltage ka-DC (noma esishintshiwe) kusixhumi sedlulisi samandla, landelela isekethe elifanele ku-fuse noma ekudluliseni okuvela kulo. Lungisa noma shintsha amafyuzi noma amafusisi angasebenzi lapho kudingeka.

Uma amandla wokufaka amandla edluliswayo nomhlabathi kukhona (kuwo wonke amatheminali afanele), sebenzisa i-DVOM ukuhlola ukusebenza komkhiqizo odluliselwe kuzikhonkwane ezifanele zokuxhuma. Uma i-voltage yesifunda sokukhipha sedluliselwe kokuphakelwa kwamandla ingahlangabezani nezidingo, sola ukuthi ukudluliswa kunephutha.

Uma amandla okukhipha amandla we-PCM adluliselwe ngaphakathi kokucacisiwe (kuwo wonke ama-terminals), hlola amasekethe wokudlulisa afanelekile ku-PCM.

Uma kutholakala isignali yamandla okukhipha edluliselwe kusixhumi se-PCM, sola i-PCM enephutha noma iphutha lokuhlela le-PCM.

Uma ingekho isignali ye-voltage ephumayo ye-PCM efanayo etholakala kusixhumi se-PCM, sola isekethe evulekile noma emfushane phakathi kokudluliselwa kwamandla kwe-PCM ne-PCM.

• Ama-fuse nama-fuse kufanele ahlolwe ngesifunda esilayishiwe ukugwema ukuxilongwa okungalungile.

Itholakala kuphi inzwa ye-P068A?

Inzwa ye-P068A

Lesi sithombe sibonisa isibonelo esijwayelekile sokudluliswa kwamandla kwe-PCM. Nokho, phawula ukuthi nakuba lokhu kudluliswa kwemali kuvame ukutholakala ebhokisini le-fuse eliyinhloko, indawo ekuyo ngempela emabhokisini e-fuse iyahlukahluka ngokwenziwa ngisho nemodeli yemoto. Futhi qaphela ukuthi ezimweni eziningi lokhu kudluliselwa kufana nje nokunye, ukudluliselwa kwamandla okungahlobene, ngakho-ke qiniseka ukuthi uhlola ulwazi oluthembekile lwesevisi lwemoto ethintekile ukuze ithole kahle futhi ikhombe i-PCM power relay.

Sicela futhi uqaphele ukuthi amazinga embonini nezinqubo ezihamba phambili zidinga ukuthi lokhu kudluliselwe kushintshwe ingxenye ye-OEM.
