Vim li cas kuv lub tsheb npav tuaj yeem tawm?

Lub tsheb npav CAN tuaj yeem tawm rau ntau qhov laj thawj, tab sis nws tseem ceeb heev kom nyob twj ywm zoo thiab tsis txhob poob siab thaum daws qhov teeb meem. Nov yog qee qhov ua rau ntawm lub npav CAN tawm:

1. Cov xov hlau xoob xoob los yog txiav tawm: Tshawb xyuas cov kab txuas txuas kom ntseeg tau tias lawv muaj kev nyab xeeb thiab zaum zoo. Ib lub xov hlau xoob los yog txiav tawm tuaj yeem cuam tshuam kev sib txuas lus hauv tsheb npav CAN.

2. Faulty ECU: Yog tias ib qho ntawm ECUs (Electronic Control Units) ua tsis tiav, nws tuaj yeem ua rau tag nrho lub kaw lus kaw. Txawm li cas los xij, feem ntau ECUs muaj cov kab ke kuaj mob uas yuav ceeb toom rau koj yog tias qhov no yog qhov teeb meem.

3. Tsawg roj teeb voltage: Ib lub roj teeb uas tsis muaj hluav taws xob kuj tuaj yeem ua rau lub tsheb npav nres. Xyuas kom tseeb tias lub roj teeb tau them tag nrho thiab tuaj yeem tswj cov khoom hluav taws xob ntawm lub cev.

4. Faulty CAN transceiver: Lub transceiver yog lub luag haujlwm xa thiab txais cov lus hla lub npav CAN. Yog tias nws ua tsis tiav, kev sib txuas lus yuav raug cuam tshuam. Ib txoj hauv kev zoo los xyuas qhov no yog hloov lub transceiver thiab saib seb qhov teeb meem puas ploj mus.

5. Lub npav thauj khoom ntau dhau: Yog tias muaj ntau yam khoom siv sim sib txuas lus ntawm lub npav CAN ib zaug, nws tuaj yeem ua rau lub kaw lus kaw. Xyuas kom tseeb tias tus naj npawb ntawm cov khoom siv ntawm lub npav tsis pub dhau nws lub peev xwm.
