Mene ne wannan yake nufi?

Wannan lambar rikitarwa ce ta matsalar matsala (DTC) wacce ta dace da motocin OBD-II tare da watsawa ta atomatik. Wannan na iya haɗawa, amma ba'a iyakance shi ba, motoci daga Ford, GMC, Chevrolet, Honda, BMW, Saturn, Land Rover, Acura, Nissan, Saturn, da dai sauransu Yayin janar, madaidaicin matakan gyara na iya bambanta da shekara, iri, samfuran wutar lantarki. da daidaitawa.

A mafi yawan lokuta, watsawa ta atomatik zai haɗa da aƙalla madaidaicin ikon sarrafawa guda uku waɗanda aka sani da soloid A, B, da C. Sabbin watsawa suna da ƙarin kayan aiki da ƙarin soloids, suna ba ku solenoids D, E, F, da dai sauransu E. DTC daban -daban. suna da alaƙa da keɓaɓɓen madaidaiciyar madaidaiciyar hanyar "D" kuma wasu daga cikin na kowa sun haɗa da P2718, P2719, P2720 da P2721. Lokacin da aka saita DTC P2721 OBD-II, tsarin kula da wutar lantarki (PCM) ya gano matsala tare da keɓaɓɓen kula da matsin lamba na sarrafawa "D". Takamaiman lambar lambobin ya dogara ne akan takamaiman matsalar da PCM ta gano.

Ana sarrafa watsawa ta atomatik ta belts da ƙuƙwalwa waɗanda ke canza kayan aiki ta hanyar amfani da matsin ruwa zuwa wurin da ya dace a lokacin da ya dace. An tsara madaidaicin matsin lamba na watsa bawul ɗin don daidaita matsin lamba don ingantaccen aikin watsawa ta atomatik da sauyawa mai sauƙi.
