Haɗin Sadarwa tare da Module Control Birke (PBCM)

Menene ma'anar hakan?

Wannan sigar tsarin sadarwa ce mai lamba na matsala wanda ya shafi yawancin kera motoci da samfura.

Wannan lambar tana nufin Module Control Control Module (PBCM) da sauran hanyoyin sarrafawa akan abin hawa basa magana da juna. Wurin da aka saba amfani da shi don sadarwa tare da shi an san shi da isar da hanyar sadarwa ta Yankin Mai Gudanarwa, ko kuma a sauƙaƙe, bus ɗin CAN.

Ba tare da wannan motar ta CAN ba, na'urorin sarrafawa ba za su iya musayar bayanai ba, kuma kayan aikin binciken ku na iya kasa samun bayanai daga abin hawa, gwargwadon abin da kewaya ya shafa.

PBCM tana karɓar babban labari daga canjin birki na shakatawa, kodayake ana aika wasu bayanai akan tsarin sadarwar bas. Waɗannan abubuwan shigar suna ba da damar module ɗin don sarrafa lokacin da aka taka birki. Yawanci, ana samun wannan akan waɗancan motocin tare da birki na diski na baya.

Matakan matsala na iya bambanta dangane da mai ƙera, nau'in tsarin sadarwa, adadin wayoyi da launuka na waya a cikin tsarin sadarwa.

Idan lambar ta dawo, nemo hanyoyin sadarwar bas na CAN C akan abin hawa naku, mafi mahimmanci mai haɗa PBCM module. Cire haɗin kebul na baturi mara kyau kafin cire haɗin mai haɗawa a cikin tsarin sarrafa PBCM. Da zarar an samo, duba abubuwan gani da wayoyi. Nemo gogewa, gogewa, wayoyi mara kyau, tabo mai ƙonewa ko narkar da filastik. Ja masu haɗin haɗin kai kuma a hankali bincika tashoshi (sassan ƙarfe) a cikin masu haɗin.
