Ungahlola kanjani inzwa ye-ABS nge-multimeter

Izinzwa ze-Anti-Lock Braking System (ABS) ziyizingxenye zezimoto zesimanje ezixhumana ne-ECU futhi zigade inani lokubhuleka uma uzama ukumisa imoto yakho.

Lawa amasensa axhunywe emasondweni ngehhanisi lezintambo eziqapha isivinini amasondo ajikeleza ngaso futhi aphinde asebenzise le-data ukucacisa ukuthi amasondo ayakhiya yini. 

Ibhuleki elifakwe nge-ABS nalo liyashesha kunebhuleki lesandla. Lokhu kusho ukuthi awusizo ezimeni ezinzima, njengalapho ushayela emigwaqweni emanzi noma eneqhwa.

Inkinga ngenzwa isho ingozi ecacile empilweni yakho, futhi i-ABS noma ukukhanya kokulawula ukudonsa kudinga ukunakwa okuphuthumayo.

Indlela yokuxilonga inzwa yezinkinga?

Umhlahlandlela wethu uzokutshela konke okudingeka ukwazi mayelana nendlela yokuhlola inzwa ye-ABS.

Ake siqale.

Kudingeka Amathuluzi Ukuhlola Inzwa ye-ABS

Kuzo zonke izivivinyo ezishiwo lapha, uzodinga

• i-multimeter
• Isethi yokhiye
• UJack
• Ithuluzi lokuskena le-OBD

I-multimeter isisiza ukuthi senze izinhlobo ezahlukene zokuxilonga izinzwa ngakho-ke iyithuluzi elibaluleke kakhulu.

Ungahlola kanjani inzwa ye-ABS nge-multimeter

Phakamisa imoto ngojeke wemoto, nqamula ikhebula lenzwa ye-ABS, setha i-multimeter kububanzi obungu-20K ohm, bese ubeka ama-probe kumatheminali enzwa. Ulindele ukuthola ukufundwa okufanele phakathi kuka-800 no-2000 ohms uma i-ABS isesimweni esihle. 

Sizocubungula le nqubo yokuhlola futhi sikubonise ukuthi ungayixilonga kanjani inkinga ngokubheka ukufundwa kwenzwa kagesi ye-AC.

1. Avule imoto

Ukuze uphephe, ufaka ugesi wemoto endaweni yokupaka futhi uvule ibhuleki eliphuthumayo ukuze inganyakazi ngenkathi ungaphansi kwayo.

Manje, ukuze ukwazi ukufinyelela inzwa ukuze uthole ukuxilonga okulula kuyo, udinga futhi ukuphakamisa imoto lapho inzwa ikhona. 

Kuye ngemoto yakho, inzwa ivamise ukutholakala ngemuva kwehabhu eyodwa yamasondo, kodwa ungabheka imanuwali yomnikazi wemoto yakho ukuze uthole indawo yayo ngqo.

Futhi ufuna ukwazi ukuthi inzwa ethile ye-ABS ibukeka kanjani emotweni yakho ukuze ungaphambanisi inzwa nezinye izinzwa.

Beka umata ngaphansi kwemoto ukuze ugcine izingubo zakho zihlanzekile ngenkathi wenza lezi zivivinyo.

2. Setha i-multimeter kububanzi obungu-20 kΩ

Setha imitha endaweni ethi "Ohm", eboniswa uphawu lwe-omega (Ω).

Uzobona iqembu lezinombolo esigabeni se-ohm semitha esimele ububanzi bokulinganisa (200, 2k, 20k, 200k, 2m kanye 200m).

Ukumelana okulindelekile kwenzwa ye-ABS kudinga ukuthi ubeke imitha ebangeni elingu-20 kΩ ukuze uthole ukufundwa okufanele kakhulu. 

3. Nqamula ikhebula le-ABS

Manje unqamula isistimu yebhuleki evimbela ukukhiya kusukela kukhebuli yenzwa ukuze uveze amatheminali ukuze ahlolwe.

Lapha unqamula kalula futhi ngobunono amahhanisi ezintambo ezindaweni zawo zokuxhuma futhi uqondise ukunaka kwakho kumahhanisi ocingo ohlangothini lwesondo.

4. Beka ama-probe kumatheminali e-ABS

Ngoba i-polarity ayinandaba lapho ukala ama-ohms, ubeka ama-probe imitha kunoma iyiphi yamatheminali enzwa. 

5. Linganisa imiphumela

Manje uhlola ukufundwa kwemitha. Izinzwa ze-ABS kulindeleke ukuthi zibe nokumelana kwe-800 ohms kuya ku-2000 ohms.

Ngokubheka imodeli yenzwa yemoto yakho, unquma izici ezifanele ukuze uhlole ukuthi uthola inani elilungile noma cha. 

Ngenxa yokuthi imitha ikubanga elingu-20 kΩ, izobonisa inani elingashintshi phakathi kuka-0.8 no-2.0 uma inzwa isesimweni esihle.

Inani elingaphandle kwalobu bubanzi noma inani eliguqukayo lisho ukuthi inzwa inesici futhi idinga ukushintshwa. 

Uma futhi uthola ukufundwa kwe-"OL" noma "1", lokhu kusho ukuthi inzwa inokumelana okufushane, okuvulekile, noma okweqile kumahhanisi okufaka izintambo futhi udinga ukuyishintsha. 

Ukuhlolwa kwe-voltage ye-ABS AC

Ukuhlola i-voltage yenzwa ye-ABS kusisiza ukuthi sithole ukuthi inzwa isebenza kahle yini ekusetshenzisweni kwangempela.

Uma imoto ikumodi yokupaka, kufakwe ibhuleki eliphuthumayo, futhi imoto iphakanyisiwe, yenza lezi zinyathelo ezilandelayo. 

1. Setha i-multimeter ibe ibanga le-voltage engu-200VAC

I-AC voltage imelelwa ku-multimeter njengokuthi "V~" noma "VAC" futhi imvamisa iba nobubanzi obubili; 200V~ futhi 600V~.

Setha i-multimeter ibe ngu-200 V ~ ukuze uthole imiphumela yokuhlolwa efaneleke kakhulu.

2. Beka ama-probe kumatheminali e-ABS

Njengesivivinyo sokumelana, uxhuma imikhondo yokuhlola kumatheminali e-ABS.

Ngenhlanhla, amatheminali e-ABS awahlukanisiwe, ngakho-ke ungavele uxhume izintambo kunoma iyiphi yamatheminali ngaphandle kokukhathazeka ngokufundwa okungalungile. 

3. Ihabhu lesondo lokuzungezisa

Manje, ukuze ulingise ukunyakaza kwemoto, uzungezisa ihabhu lamasondo i-ABS exhunywe kuyo. Lokhu kukhiqiza i-voltage, futhi inani le-volt elakhiwe lincike ejubaneni lesondo.

Ufuna ukwenza isiqiniseko sokuthi uphotha isondo ngesivinini esingaguquki ukuze uthole inani elingaguquki kukhawunta.

Okwesivivinyo sethu, wenza uguquko njalo ngemizuzwana emibili. Ngakho awujabuli ngokuphenduka kwesondo.

4. Hlola i-multimeter

Kuleli qophelo, i-multimeter kulindeleke ukuthi ibonise inani le-voltage. Ngesivinini sethu sokujikeleza, i-voltage ye-AC ehambisanayo icishe ibe ngu-0.25 V (250 millivolts).

Uma ungakutholi ukufundwa kwemitha, zama ukuxhuma iharness yenzwa lapho ingena khona kuhabhu lamasondo. Uma namanje ungakutholi ukufundwa lapho uhlola i-multimeter yakho, kusho ukuthi i-ABS yehlulekile futhi idinga ukushintshwa. 

Ukuntuleka kwamandla kagesi noma inani le-voltage elingalungile nakho kungabangelwa inkinga yehabhu lamasondo ngokwalo. Ukuze uhlole lokhu, buyisela i-ABS inzwa entsha bese uphinda uhlola i-voltage enembile. 

Uma namanje ungakutholi ukufundwa kwe-voltage efanele, inkinga ngehabhu lamasondo futhi udinga ukuyishintsha. 

Ukuxilongwa ngeskena se-OBD

Isithwebuli se-OBD sikunikeza isixazululo esilula sokuhlonza izinkinga ngenzwa yakho ye-ABS, nakuba zingalungile njengokuhlolwa kwamamitha amaningi.

Ufaka isithwebuli endaweni yokufunda ngaphansi kwedeshi bese ubheka amakhodi amaphutha ahlobene ne-ABS. 

Wonke amakhodi amaphutha aqala ngohlamvu "C" akhombisa inkinga ngenzwa. Isibonelo, ikhodi yephutha engu-C0060 ikhombisa inkinga nge-ABS engaphambili kwesokunxele futhi i-C0070 ikhombisa inkinga nge-ABS engaphambili kwesokudla.

Bheka lolu hlu oluphelele lwamakhodi ephutha e-ABS nezincazelo zawo ukuze uthole ukuthi yini ongayilindela.

isiphetho

Inzwa ye-ABS iyingxenye elula yokuhlola futhi inikeza izindlela ezihlukahlukene zokuxilonga izinkinga ezimotweni zethu.

Nokho, nganoma yikuphi ukuhlola ofisa ukukwenza, qiniseka ukuthi usebenzisa izinyathelo zokuphepha ezifanele futhi usethe i-multimeter yakho ebangeni elifanele ukuze uthole imiphumela efanele.

Njengoba kushiwo esihlokweni sethu, khumbula ukuthi ukuphepha kwakho emgwaqeni kuncike kakhulu ekusebenzeni kwe-ABS yakho, ngakho-ke noma iyiphi ingxenye enesici kufanele ishintshwe ngokushesha ngaphambi kokuba imoto iqale ukusebenza.

Imibuzo evame ukubuzwa

Mangaki ama-ohm okufanele inzwa ye-ABS ibe nawo?

Inzwa enhle ye-ABS kulindeleke ukuthi ibambe phakathi kuka-800 ohms no-200 ohms ukumelana kuye ngemoto noma imodeli yenzwa. Inani elingaphandle kwalokhu lisho ukujikeleza okufushane noma ukumelana okunganele.

Ngazi kanjani uma ngabe inzwa yami ye-ABS yimbi?

Inzwa ye-ABS embi ikhombisa izimpawu ezifana ne-ABS noma ilambu le-traction control kudeshibhodi eliqhamukayo, imoto ithatha isikhathi eside ukuma, noma ukungasebenzi kahle okuyingozi uma ibhuleka ezimeni ezimanzi noma ezineqhwa.
