P0884 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0884 qhia txog qhov sib cuam tshuam / tsis zoo hauv hluav taws xob kis tau tus mob tswj module (TCM) lub zog tawm tswv yim teeb liab.

Qhov txhaum cai txhais li cas P0884?

Teeb meem code P0884 qhia tias muaj teeb meem nrog cov hluav taws xob kis tau tus mob tswj module (TCM) lub zog nkag, uas ua rau muaj teeb meem tsis sib xws lossis tsis ruaj khov. Lub tshuab hluav taws xob tswj kev sib kis feem ntau tsuas yog tau txais lub zog thaum lub qhov hluav taws xob hloov pauv nyob rau hauv ON, RUN, lossis RUN txoj haujlwm. Lub zog hluav taws xob no feem ntau tiv thaiv los ntawm lub fuse, fuse txuas lossis relay. Feem ntau lub cav tswj module (PCM) thiab kis tau tus mob tswj modules yog powered los ntawm tib relay, txawm nyob rau hauv nyias circuits. Ntawm qee cov qauv tsheb, tus tswj kev sib kis yuav muab lub kaw lus rau hauv hom limp, txwv lub zog muaj rau 2-3 nkaus xwb.

Tej zaum ua rau

Qee qhov laj thawj rau P0884 teeb meem code:

• Muaj ib qho malfunction nyob rau hauv hluav taws xob Circuit Court muab lub hwj chim rau lub TCM.
• Kev sib txuas tsis zoo lossis oxidation ntawm kev sib cuag hauv hluav taws xob hluav taws xob.
• Kev puas tsuaj lossis puas fuse, fuse txuas, lossis relay muab lub zog rau TCM.
• Teeb meem nrog TCM nws tus kheej, xws li cov khoom siv sab hauv tsis zoo lossis ua haujlwm tsis zoo.
• Muaj kev ua haujlwm tsis zoo hauv lwm cov khoom uas cuam tshuam rau TCM lub zog hluav taws xob, xws li cov xaim lossis cov khoom siv.
