nimeleta huu uzi ili uweze kutatua matatizo madogo madogo ambayo unaweza kuyatatua kwenye gari yako pindi linapo leta hitilafu upande wa umeme na kuwasha taa za tahadhari kama taa ya CHECK ENGINE, ABS,O/D,VSV,TRS,SRS or AIRBAG n.k
hapa tutafahamishana na kusaidiana kuweza kuipima gari yako bila kutumia mashine diagnosis machiney na ukapata majibu sawa kabisa na ya uhakika.
nitajitahidi kuzungumzia mifumo yote ila hasa nitaanza na mifumo mikubwa mitatu na jinsi ya kutatua tatizo ambalo utalipata baada ya kuipima gari yako.
JINSI YA KUPIMA GARI YAKO.
hili linaweza kufanywa na mtu ambaye ni fundi au hata kama sio fudi pia inategemeana na akili ya mtu. gari za toyota zina socketi za aina 4 tofauti hizi zinatofautiana au zilikuwa zinatoka kufuatana na aina ya gari.
magari ya zamani kabisa yalikuwa yanatumia socket ya round.
ila kwa magari ya sasa yanatumia socket mbili ya obd 1 ambayo huwa inakuwa mbele kwenye bonet huwa na pin 22.

kimwonekano huwa inakuwa hivyo. ukiangalia kwenye hiyo picha kuna sehem nyingine hazina pin zipo empty huwa inategemeana na aina ya gari na niyamwaka gani kama gari ni ya miaka ya karibuni utaona hiyo socket pin karibia zote zina clips.
ukifunua huo mfuniko kwa juu utaona kuna vifupisho au herufi nyingi nyingi lakini herufi zinazotumika kwaajili ya kupimia au nitakazo zizungumzia hapa ni herufi kama 4 au 5 tuu katika soketi hii.
1=E1 hii ni erth au negative au graund
2=T1 hii pin itakuwezesha kupima matatizo ya engine/chek engine
3=TC hii pin itakuwezesha kupima matatizo ya ABS na mifumo shiriki ya abs.
4=TS hii pin itakuwezesha kupima matatizo ya SRS,AIRBAG.

mwonekano wa hiyo soketi kimpangilio wa hizo pin utaonekana hivyo.
SOKETI YA PIN 16 OBD 2.
hii soketi ipo kwenye magari yote ya kisasa ya sasa hivi au kuanzia mwaka 2000 kuja juu hata baadhi ya magari ya chini ya 2000 yanazo pia.
hii soketi huwa inakuwa ndani ya gari na huwa inakuwa upande wa dereva .mara nyingi huwa inakuwa karibu kabisa na sehem ya kufungulia bonet kwa njini au ndani .
mwonekano wa wa hiyo soketi ya pin 16 OBD 2.zingatia sana hizo namba.
katika hii soketi tutazungumzia pin kama 3 hivi . sasa hapa umakini kidogo unatakiwa maana usipokuwa makini utajikuta badala ya kutengeneza unaharibu zaidi.
4=CG chassis ground hii ni sawa sawa na E1 kwenye soketi ya pin 22.
5=SG hii ni signal ground ECM ground.au E2 mafundi watanielewa kwa urahisi.
12=hii pin itakuwezesha kupima matatizo ya SRS,AIRBAG
13=TC hii pini inakazi kubwa sana na nyingi itakuwezesha kupima matatizo karibia yote kwenye mifumo yote kama inashida ,hapa na maanisha abs,od,chek engine,TRS,VSC nakadharika.
HATUA ZA KUIPIMA GARI YAKO.
baada ya kuzifaham hizo soketi tuangalie sasa kwakutumia hizo soketi utawezaje kupima gari yako na kutambua ina shida gani au sababu iliyosababisha mpaka taa kuwaka na utawezaje kutatua tatizo lako .nazani nianze hasa na jinsi ya kupima taa ya check engine.
kama gari yako inatumia soketi ya pini 22 basi fanya hivi.zima gari yako iweke off kabisa.chukua kipande cha waya chomeka kwenye pin
E1 na pin
T1
angalia mfano kwenye picha hapa
baada ya hapo ingia ndani ya gari na weka switch ON usiwashe gari.angalia taa ya chek engine utaona ina blink au inawaka kwa kukonyeza konyeza,au kwa lugha nyingine ina flush.sasa hapo kuwa makini kuhesabia ina blink mara ngapi na kutulia kidogo harafu inaendelea tena.nitakueleza baadae jinsi ya kuyasoma au yahesabu hayo mapigo ya check engine kuwaka na kuzima.
KUPIMA KWA SOKETI YA OBD 2 AU PIN 16
hapa pia zima gari yako kabisa iweke switch off harafu chukua kipande cha waya na chomeka kwenye pin number 4 CG na pin 13 TC.
baada ya hapo ingia ndani ya gari yako weka switch ON harafu angalia taa ya chek engine inavyo blink lakini hapa kutakuwa na utofauti kidogo sio taa ya check engine peke yake ndio ita blink utaona taa nying sana ziki blink kwa kuwa katika soketi hii pin hii ya TC inafanya kazi nyingi.au inachukua mawasiliano ya mifumo mingi sana .sasa wewe weka umakini wako kwenye taa husika tuu ili usichanganyikiwe.
JINSI YA KUSOMA FAULT CODE.
hapa tuangalie ni jinsi gani unaweza kusoma fault code au namna ya taa inavyowaka na kuzima na kuweza kupanda namba sahihi zitakazo kuwezesha kukujulisha kuwa gari yako ina shida gani au ni sensor ipi haifanyi kazi au imekufa.
no fault code gari kama itakuwa haina tatizo au hakuna shida iliyolipotiwa kwenye control box na kuhifadhiwa taa itawaka itawaka na kuzima bila kuwa na tofauti hapa na maana itawaka sekunde 0.5 na kuzima 0.5 tena itawaka 0.5 na kuzima 0.5 itaendelea hivyo bila kusimama.
hapa sio magari yote huwa kwa sekunde hiyo mengine huwa na pazi huhesabu taratibu main point kubwa hapo ni kuwa kusiwe na tofauti yoyote kati ya kuzima na kuwaka kuzima na kuwaka kama kutakuwa na tofauti ina maana hiyo ni fault code.
na fault code za toyota zote duniani zinaanzia namba 2 mpaka 99. hapo namba 1 sijaiandika kwa kuwa gari ikisoma namba moja ina maana haina tatizo.
usomaji wa fault code kuanzia namba 2 mpaka 9 unakuwa hivi.
mfano gari code namba 2 taa itawaka hivi.
ukiweka tuu switch on taa itawaka na kuzima harafu itawaka nakuzima tena. wewe hapo utakuwa unahesabu imewaka mara ngapi. na siku zote code kuanzia namba 2 mpaka 9 huwa inawaka na kuzima mfululizo.bila kuwa na tofauti ya mda kati ya muwako mmoja na mwingine.
code 5 itakuwa hivi on of on of on of on of on hapo itawaka mfululizo harafu itatulia kidogo itaanza tena kuwaka kama mwanzo ina maana hapo gari inarudia tena kuhesabu code husika.
code namba 10 mpaka 99
code 11 itawaka hivi on of on of on of on of on of on of.
hapo ina maana on of ni sawa na 1 on of ni moja nyingine kwahiyo inakuwa 11 itatulia kidogo na kurudia tena kuhesabu kama mwanzo.
code 15 itawaka hivi on of on of on of on of on of on of.
hapo ina maana on of ni 1 harafu itaweka pozi kidogo harafu itapiga on of on of on of on of on of hapo ina maana code 5. baada ya hapo itaweka pozi lefu zaidi na kuanza tena upya.
code 22 itawaka hivi on of on of on of on of.
kama mtakuwa mmenielewa hapo basi ngoja tuone gari yenye fault code zaidi ya moja.
itasomaje taa ya check engine.
mfano ina code 11,15 na 23 itasoma hivi,
on of on of on of on of on of on of on of on of on of on of on of on of on of ikamaliza hapo itarudi mwanzo kabisaa na itarendelea kurudia mpaka utakapo weka switch off au kuchomoa kipande cha waya.
ukisha weza kusoma fault code basi unakuwa umemaliza kazi ya kulipima gari lako.hizo namba unazozipata au hizo fault code huwa zinakuwa na maana yake kulingana na aina ya gari na huwa zinatofautiana kila gari au aina ya gari inategemeana gari inatumia engine gani.au nitoleo la mwaka gani.

mafundi na wadau wote ambao wanapenda magari au wanamiliki magari njooni hapa tujadili elimishana na kutatua matatizo ya magari yetu.haina haja ya kusumbuka kuanza kubahatisha katika kutengeneza gari yako unatumia garama kubwa kununua au kubadilisha vitu ambavyo sio vibovu njia hii ukiweza kuitumia itakusaidia sana kupunguza garama. huna haja ya kupima na mashine .kama upo mahali ambapo hakuna mashine tumia njia hii.
wadau wote ambao hamjaelewa ruksa kuuliza au kukosoa kwa lengo la kuelimishana na kuongezeana maalifa pia .haya nimeyaandika kwa uelewa wangu kama kuna mdau ana ya ziada zaidi anaweza ongezea pia.
huu uzi nitakuwa naendelea kuuongezea kila nipatapo mda sito anzisha uzi mwingine matatizo yote ya toyota upande wa umeme yata tatuliwa hapa.
nimegusia kidogo sana kwenye mfumo wa chek engine nitakuja pia kuelezea sensor moja moja kazi yake na hasara zake ikiwa haifanyi kazi kama fault code zinavyo soma hapo juu.
pia nitagusia mifumo yote jinsi ya kupima na kujua tatizo pindi taa za kwenye dash board zinapo waka.
itaendelea
