Tshawb nrhiav seb yuav kuaj xyuas lub tsheb koj tus kheej li cas thiab txuag ntawm kev pabcuam tsheb.

ELM327 yog dab tsi

Lub npe ELM327 paub txog ntau tus tswv tsheb. Qhov no yog lub scanner lossis adapter uas txuas rau lub khoos phis tawj ntawm lub tsheb ntawm OBD-II connector. Cov cuab yeej siv tau zoo yog siv los kuaj xyuas qhov ua haujlwm tsis zoo, nyeem cov ntsuas kev ua haujlwm thiab rov pib ECU (electronic control unit) yuam kev.

Lub tshuab scanner tau txais nws lub npe los ntawm lub npe ntawm microcontroller, uas yog ib hom kev sib txuas ntawm lub tsheb kuaj mob ntawm lub tsheb thiab lub computer lossis smartphone. Cov nti no tsim los ntawm lub tuam txhab Canadian tau poob rau hauv tes ntawm Tuam Tshoj electronics manufacturers, uas tsis nco lub caij nyoog luam nws.

ELM327 scanner ua dab tsi

Kev ua haujlwm ntawm ELM327 yog qhov dav heev. Tab sis nws feem ntau nyob ntawm kev txhawb nqa ntawm qee lub peev xwm los ntawm ib qho tshwj xeeb ntawm lub adapter, ECU ntawm lub tshuab nws tus kheej, nrog rau cov software uas siv rau kev kuaj mob.

Ntxiv nrog rau kev nyeem ntawv, kev txiav txim siab thiab tshem tawm cov kev kuaj mob yuam kev, lub scanner tuaj yeem tso saib lub sijhawm ntawm lub cav nrawm thiab nrawm ntawm lub tsheb, qhov kub thiab txias ntawm tag nrho cov kua, cov roj tam sim no thiab huab cua noj, txoj hauj lwm ntawm lub tshuab valve, lub siab nyob rau hauv cov roj system thiab ntau yam ntxiv.

Hauv qee lub tsheb, siv ELM327 adapter, koj tuaj yeem qhib thiab rov kho qhov tsis siv neeg kaw thiab folding ntawm daim iav, lub teb ntawm cov roj pedal, thiab cov ntaub ntawv dashboard.

Yuav ua li cas xaiv ELM327

Vim muaj ntau lub clones ntawm qhov zoo sib txawv, muaj kev pheej hmoo ntawm kev khiav mus rau hauv lub cuab yeej nrog txo kev ua haujlwm, uas yuav tsis ua haujlwm kom raug lossis yuav tsis pib txhua. Muaj peb lub ntsiab lus tseem ceeb los xav txog thaum yuav khoom.

1. Hom kev sib txuas

Muaj ntau ntau versions ntawm ELM327 nrog sib txawv kev sib txuas interfaces. Feem ntau yog adapters nrog Bluetooth, Wi-Fi thiab USB. Lawv txawv tsis tsuas yog nyob rau hauv kev sib txuas, tab sis kuj nyob rau hauv compatibility nrog smartphones thiab computers. Lwm cov haujlwm zoo ib yam.

• Bluetooth yog qhov pheej yig tshaj scanners uas tsuas yog ua haujlwm nrog Android smartphones.
• Wi-Fi - kim dua versions, tau tshaj Android thiab iOS smartphones thiab khoos phis tawj.
• USB yog me ntsis pheej yig dua Wi-Fi scanners. Lawv ua haujlwm nrog cov khoos phis tawj nkaus xwb, tab sis lawv txawv ntawm kev ntseeg siab ntawm kev sib txuas lus.

2. Firmware version

Adapters software yog hloov kho tas li. Ntawm tus thawj ELM327, tam sim no version yog twb 2.2. Suav clones raug muag nrog firmware 1.5 thiab 2.1. Oddly txaus, qhov tsis ntev los no version yog phem dua.

Lub nti uas tau mus rau Suav muaj firmware version 1.5. Tag nrho cov clones nrog cov firmware no muaj tus thawj ELM327 software. Tom qab ntawd, cov ntawv luam ntawm scanners version 2.1 tau tshwm sim. Cov tom kawg tsuas yog hloov kho firmware 1.5, thiab tsis yog qhov zoo dua - txhawm rau txo tus nqi ntawm kev tsim khoom, Suav tau tshem tawm ntau txoj kev sib txuas lus. Tsis tas li ntawd, muaj cov hloov pauv tsis tu ncua nrog version 1.5 uas tau muag hauv qab ntawm 2.1.

Qhov tseeb, peb versions ntawm ELM327 clones yog tam sim no ntawm kev muag khoom:

• ELM327 1.5 - qub tab sis qub firmware;
• ELM327 2.1 - stripped-down thawj firmware nyob rau hauv lub guise ntawm ib tug tshiab dua;
• ELM327 2.1 - thawj firmware disguised li tshiab, tab sis tsis muaj kev hloov pauv.

Pom tseeb, nws tsim nyog yuav lub adapter nrog tus thawj firmware version 1.5. Piv txwv li, ntawm no yog ib qho ntawm cov neeg muag khoom ntseeg siab uas koj tuaj yeem yuav tus nqi pheej yig.

3. Hom kev kuaj mob tsis siv neeg txuas

Rau qee lub tsheb, tshwj xeeb tshaj yog ua ntej xyoo 2000 thiab cov khoom siv hauv tsev, cov khoom siv tshuaj ntsuam xyuas muaj cov ntaub qhwv ntawm lwm cov qauv. Txuas lub scanner rau lawv ncaj qha yuav tsis ua haujlwm. Rau cov xwm txheej zoo li no, cov khoom siv tshwj xeeb yog siv: ntawm ib sab, lawv muaj qhov sib txuas rau cov qauv tsheb tshwj xeeb, thiab ntawm qhov tod tes, tus qauv OBD-II.

Proprietary pads tuaj yeem muaj qhov sib txawv thiab muaj pes tsawg tus neeg sib cuag. Yog li ntawd, ua ntej yuav ib lub scanner, xyuas seb tus qauv connector siv rau koj lub tsheb, thiab, yog tias tsim nyog, yuav lub adapter tsim nyog.

Yuav ua li cas txheeb xyuas ELM327 scanner

Tom qab yuav lub ELM327 adapter, xyuas tias nws yog tiag tiag version 1.5. Thaum xaj los ntawm AliExpress, xyuas seb PIC18F25K80 nti tau nruab rau hauv nws thiab hais qhia tias koj yuav kuaj xyuas lub scanner nrog software tshwj xeeb thiab qhib qhov kev tsis txaus siab thaum muaj teeb meem.

1. Kev kuaj sab nraud

Nws tsis yog yooj yim heev rau visually txheeb xyuas qhov zoo adapter. Opaque lossis tsaus yas vaj tse ua rau nws tsis tuaj yeem kuaj xyuas cov khoom. Lawv qhov me me thiab cov cim nyuaj-rau-nyeem ntawv ua rau muaj teeb meem ntau dua.

Yog tias koj ua tib zoo qhib rooj plaub, koj tuaj yeem saib ntawm ELM327 boards. Saib ze ntawm txhua qhov chaw thiab nrhiav tus processor nrog tus lej PIC18F25K80. Firmware 1.5 tsuas yog xav tau cov nti zoo li no, yog li nws lub xub ntiag yuav yog qhov lav zoo.

2. Daim ntawv thov tester

Ib daim ntawv thov tshwj xeeb kuaj kev sib raug zoo nrog cov txheej txheem kev kuaj xyuas tsheb npav thiab qhia qhov tseeb version ntawm lub scanner. Txhawm rau kuaj xyuas, ua cov hauv qab no.

1. Ntxig lub ELM327 adapter rau hauv lub tsheb kuaj lub qhov (socket) thiab qhib qhov hluav taws xob.
2. Qhib Bluetooth lossis Wi-Fi chaw ntawm koj lub smartphone thiab ua ke nrog lub adapter (password: 0000 lossis 1234).
3. Nruab daim ntawv thov rau kev sim thiab nias lub pob "Txuas".
4. Tos kom lub scan kom tiav thiab xyuas cov txiaj ntsig.
5. Kev ua haujlwm tau zoo nrog ntau lub npe tsheb yog lav yog tias lub adapter txhawb txhua qhov kev hloov kho mus txog 1.4 lossis 1.4b suav nrog.

Yuav ua li cas txuas rau lub tsheb

Cov txheej txheem teeb tsa tseeb yog feem ntau tau piav qhia hauv cov lus qhia.

Kauj Ruam 1. Txhim kho Daim Ntawv Thov Kev Ntsuas

Ntau yam kev pab cuam yog siv los txuas rau lub computer ECU. Muaj ob qho tib si dawb thiab them nyiaj versions rau Android, iOS thiab Windows. Nrog rau lub scanner nws tus kheej, qhov tsim nyog software feem ntau twb muaj nyob rau hauv cov khoom siv. Nruab nws lossis ib qho ntawm cov apps nrov.

Kauj ruam 2. Txuas ELM327

Lub connector rau ELM327 adapter nyob txawv hauv tsheb. Feem ntau qhov chaw hauv qab lub kauj tsheb lossis hauv lub hnab looj tes, tab sis hauv qee cov qauv qub nws kuj tseem nyob hauv qab lub hood. Xyuas seb nws nyob hauv koj lub tsheb li cas thiab txuas lub scanner.

Kauj ruam 3. Pairing li

Tom ntej no, koj yuav tsum qhib lub ignition thiab tsim kom muaj kev sib txuas ntawm lub scanner thiab lub smartphone lossis laptop. Yog tias lub adapter muaj lub pob pib, nco ntsoov nias lub pob ntawd thiab.

Qhib Bluetooth lossis Wi-Fi hauv qhov chaw gadget thiab tos kom txog thaum pom cov khoom nyob ze. Xaiv ELM327 adapter: feem ntau hu ua OBDII. Txuas rau nws. Siv tus lej 0000 lossis 1234 los ua khub.

Kauj ruam 4. Daim ntawv thov configuration

Khiav daim ntawv thov kev kuaj mob uas tau teeb tsa. Feem ntau, hom adapter yuav raug kuaj pom. Yog tias tsis yog, qhib daim ntawv thov teeb tsa, qhia meej hom kev sib txuas (Bluetooth, Wi-Fi lossis USB) thiab xaiv lub scanner muaj los ntawm daim ntawv teev npe.

Yuav siv ELM327 scanner li cas

Yog tias txhua yam ua tiav kom raug, tom qab kev teeb tsa, cov ntaub ntawv hais txog lub tsheb yuav tshwm rau ntawm qhov screen, thiab cov sensors thiab cov ntsuas yuav ua haujlwm. Nyob ntawm daim ntawv thov, tej zaum koj yuav tau tsim ib qho profile pib. Txhawm rau ua qhov no, xaiv koj tus qauv los ntawm cov npe thiab qhia txog cov yam ntxwv ntawm kev ua haujlwm.

Tam sim no koj tuaj yeem saib cov kev ua haujlwm ntawm lub cav thiab ntau lub tshuab, nyeem ECU yuam kev thiab rov pib dua. Cov apps muaj cov nyees khawm sib raug rau txhua txoj haujlwm. Piv txwv li, hauv cov khoom siv Torque nrov tshaj plaws no yog "Dashboard", "Kev nyeem ntawv yuam kev", "Graphs" thiab lwm yam.
