1. Handheld Diagnostic Tools
- Hom:
- Basic Code Readers: Cov khoom siv yooj yim uas khaws thiab tshem tawm Cov Cai Teeb Meem Teeb Meem (DTCs).
- Advanced Scanners: Cov cuab yeej muaj txiaj ntsig zoo nrog cov ntaub ntawv nyob hauv streaming, khov thav duab tsom, thiab kev pabcuam rov pib dua (xws li ABS, SRS, TPMS).
- Cov yam ntxwv tseem ceeb:
- Kev sib txuas ncaj qha rau OBD2 chaw nres nkoj ntawm cable.
- Built-in npo rau kev ua haujlwm ib leeg.
- Txwv rau qhov yooj yim lossis lub tsheb tshwj xeeb ua haujlwm nyob ntawm tus qauv.
2. Wireless Diagnostic Tools
- Hom:
- Bluetooth/Wi-Fi Adapters: Cov dongles me me uas ua ke nrog smartphones / ntsiav tshuaj.
- Cov khoom siv Wireless Professional: Ntau cov txheej txheem rau kev kuaj mob siab dhau ntawm cov apps.
- Cov yam ntxwv tseem ceeb:
- Kev sib txuas wireless (Bluetooth, Wi-Fi, lossis huab-based).
- Cia siab rau tus khub apps / software rau cov ntaub ntawv tso saib thiab tshuaj xyuas.
- Txhawb nqa cov ntaub ntawv hauv lub sijhawm tiag tiag, kev kuaj mob tej thaj chaw deb, thiab hloov kho firmware.
Qhov txawv ntawm Handheld thiab Wireless Tools
| Yam | Cov cuab yeej tuav tes | Cov cuab yeej Wireless |
|---|---|---|
| Kev sib txuas | Wired (OBD2 chaw nres nkoj) | Wireless (Bluetooth / Wi-Fi) |
| Portability | Bulky, standalone ntaus ntawv | Compact, tso siab rau ib qho khoom siv mobile |
| Kev ua haujlwm | Txwv los ntawm hardware/software | Expandable ntawm app hloov tshiab |
| Tus neeg siv interface | Built-in npo thiab cov nyees khawm | Mobile / ntsiav tshuaj app interface |
| Nqi | 20-500+ (cov cuab yeej kawm qib siab) | 10-300+ (adapter + app subscription) |
Lub luag haujlwm ntawm OBD2 Cov ntaub ntawv rau cov neeg siv sib txawv
- Rau cov tswv tsheb:
- Basic Code Nyeem Ntawv: Txheeb xyuas cov teeb meem tshwm sim rau lub Teeb Tsav Tsheb (CEL) (piv txwv li, P0171: ntshiv roj sib tov).
- DIY Troubleshooting: Tshem tawm cov lej me me (piv txwv li, evaporative emissions leaks) los yog saib xyuas roj efficiency.
- Kev txuag nqi: Zam kev mus ntsib kws kho tsheb tsis tsim nyog rau kev kho yooj yim.
- Rau cov kws tshaj lij kws tshaj lij:
- Advanced Diagnostics: Txheeb xyuas cov ntaub ntawv nyob (xws li, MAF sensor nyeem, oxygen sensor voltages) txhawm rau txheeb xyuas cov teeb meem.
- Cov Kev Xeem Tshwj Xeeb: Ua cov kev ua, hloov kho, lossis ECU programming (xws li, throttle relearn, injector coding).
- Kev ua tau zoo: Txhim kho kho nrog bidirectional tswj thiab coj kev daws teeb meem.
Cov ntaub ntawv tseem ceeb / Code piv txwv
- DTCs: Codes zoo lip0300 ua(random misfire) qhia pib teeb meem.
- Cov ntaub ntawv nyob: Parameters nyiamRPM, STFT / LTFT Cov(fuel trims), thiabO2 sensor voltagesqhia lub sijhawm tiag tiag lub cav kev ua haujlwm.
- Khov Ncej: Captures tsheb tej yam kev mob (ceev, load, thiab lwm yam) thaum muaj teeb meem tshwm sim.
Cov ntsiab lus
Cov cuab yeej Handheld haum rau cov neeg siv nyiam kev yooj yim thiab siv offline, thaum cov cuab yeej wireless muab kev yooj yim thiab cov yam ntxwv siab heev ntawm cov apps. Rau cov tswv, cov cai nkag yooj yim pab kho sai; rau cov kws tshaj lij, kev soj ntsuam cov ntaub ntawv sib sib zog nqus ua kom muaj tseeb, kho tau zoo. Ob lub cuab yeej txhawb nqa cov neeg siv los siv OBD2 cov ntaub ntawv rau kev txiav txim siab paub.
