Chida Chowunikira cha OBD2 Code Scanner: MIL Lamp Function, Zoyambitsa, ndi Utility Data

Dashboard ikuwoneka MIL ?

1. Kodi MIL (Lamp Indicator Lamp) ndi chiyani?

MIL, yomwe nthawi zambiri imatchedwa "Check Engine Light," ndi nyali yochenjeza pa dashboard yolamulidwa ndi miyezo ya OBD2.

Imawunikira pamene Engine Control Unit (ECU) yagalimoto imazindikira vuto lomwe likukhudza mpweya, magwiridwe antchito a injini, kapena makina ovuta. Maiko awiri akuwonetsa kuuma:

• Kuwala Kokhazikika: Nkhani yosafunikira koma yosalekeza (mwachitsanzo, kuwonongeka kwa kansalu ka oxygen).
• Kuthwanima: Chiwopsezo chowopsa chanthawi yomweyo (mwachitsanzo, kuwonongeka kwa ma converter kuchokera kumoto).

2. Zomwe Zimayambitsa Kutsegula kwa MIL

Zolakwika zomwe zimayambitsa MIL nthawi zambiri zimakhudzana ndi mpweya kapena injini, monga:

• Kulephera kwa sensa(mwachitsanzo, sensa ya okosijeni, MAF, sensa ya throttle position).
• Nkhani zowongolera umuna(mwachitsanzo, chosinthira cholakwika chothandizira, kutayikira kwa EVAP).
• Mavuto oyaka moto / owopsa(monga ma spark plugs, ma jekiseli amafuta).
• Zolakwika zamagetsi zamagetsi(mwachitsanzo, mawaya, zolakwika za kulumikizana kwa ECU).

3. Diagnostic Data ndi Codes

• Ma Code of Diagnostic Trouble (DTCs): Makhodi okhazikika (mwachitsanzo, P0171, P0300) amalozera komwe kulakwa.
• Live Data Stream: Zowerengera zenizeni zenizeni / zowerengera (mwachitsanzo, RPM, chepetsa mafuta, ma voltages a sensor).

4. Zothandiza kwa Okhudzidwa

• Kwa Eni Magalimoto:
  • Kuzindikira: Zidziwitso za MIL za ngozi zomwe zingachitike pachitetezo / mpweya, kupewa kukonzanso kokwera mtengo kapena kulephera kuwunika.
  • Malangizo Oyambira: Ma DTC a Generic (mwachitsanzo, P0420) amathandiza eni ake kumvetsetsa zachangu (mwachitsanzo, "Catalyst Efficiency Below Threshold").
• Za Amisiri:
  • Kukonza Zolinga: DTCs yopapatiza kukula kwa matenda (mwachitsanzo, P0301 = Cylinder 1 misfire).
  • Kusanthula koyendetsedwa ndi data: Zomwe zili pompopompo (mwachitsanzo, kuchuluka kwamafuta, mawonekedwe a sensor ya O2) zimazindikiritsa zovuta zapakatikati kapena kuwonongeka kwa zinthu.
  • Kutsata kwa Emission: Imawonetsetsa kuti kukonzanso kumakwaniritsa zofunikira.

5. Chotengera Chofunikira

Chidziwitso cha eni ake a MIL ndi OBD2 ndi luso laukadaulo. Eni ake amalandila machenjezo oyambilira, pomwe akatswiri amagwiritsa ntchito manambala ndi data yamoyo kuti akonze bwino, akonze zolondola, kuchepetsa nthawi yocheperako komanso kuwopsa kwa mpweya.
