Daca nu ma insel, dupa orice interventie asupra acelor clapete trebuie calibrate pt a functiona corect.

 

Fa o diagnoza la masina cu al 2lea calculator cu care iti da antiskid. Vezi daca mai ai erorile de clapeta. Daca nu mai ai erorile de clapeta, inseamna ca se rezolva cu un alt ECU.

Cum ti-am zis si in pm, ori al 2lea nu a fost clonat cum trebuie, ori desi are acelasi cod, el fizic e diferit, pentru ca mie eticheta de pe el imi pare altfel decat cea originala. 

Repet, daca cu al 2lea ECU, la diagnoza, nu mai apar codurile alea de eroare, inseamna ca daca pui  alt ECU bun iti rezolva problema.

Chiar daca ala iti da antiskid din diverse motive, daca e defectul din instalatie/clapeta/orice diferit de ECU, ar trebui sa iti dea si erorile alea de la clapeta. Daca nu le mai da, inseamna ca e din ECU.

am masurat.

Bateria contact pus 11.75 V

bypass valve

pin #4 + # 5 - 11.71 V

pin #5 + # 6 - 0 V

inlet valve

pin #4 + # 5 - 2.78 V

pin #5 + # 6 - 0 V

Am gasit o diagrama electrica (atasata) in care arata ca pin #5 este fir de masa

cu motorul pornit bateria imi arata voltaj 12.57. nu e prea mic.... n-ar trebui sa fie undeva intre 14-14.5 V ?

corpul de valve l-am shimbat la Volvo, cred ca au facut calibrare.... cum pot sa verific asta ?

Ba da, ar trebui sa incarce 14-14.5. Masoara incarcarea direct intre surubul de + al alternatorului si o masa de pe motor. Daca tot atat ai, e timpul pt alt alternator sau refacut al tau, poate de aici pleaca toate problemele tale

aha !!!

poti sa imi spui unde e surubul asta de plus ?

eu am vazut doar un cablu gros prins cu un surub de alternator si citeva fire care intra intr-o mufa in alternator

Cablul gros cu surub e + , - il iei de pe blocul motor .

Sper sa o rezolvi !  Masina incarca in functie de temperatura (senzor sub baterie) oricum ar trebui sa fie 13.5-14.5

cred ca eu am masurat ieri numai cind bateria era cu contact pus dar fara motor pornit.

acum, cu motorul pornit imi arata la iesirea de la alternator 14.98 V si la bornele bateriei 14.88 V.

cu motorul oprit bateria arata mai putin 12.32 V

Este ok in cazul asta, desi 14.9 e cam multicel la borne dar totusi ok pt o masina proaspat pornita si vreme rece, Mai scade dupa ceva timp spre 14.5

ok.

multumesc.

atunci concluzia este ca corpul de valve este bun ? si ca firele sint ok ?

Am citit un pic pe diagonala e drept, dar intrebare-intrebatoare - ai facut si backprobing ? (mufele bagate, si te "intepi" in pin prin spatele mufei) si sa masori aceleasi lucruri ? Teoretic trebuie masurat cu breakout box-ul unii parametri.

da

asa am facut ieri masuratorile..... in timp ce mergea motorul (inainte sa dau jos corpul de valve) am intepat firele cu un bold.

astea au fost masuratorile:
bypass air control valve
 pin #1 - 4.98 V
       #3 - 14.79 V
       #4 - 14.79 V
       #5 - 0 V
       #6 - 3.75 V

 inlet control valve
 pin #1 - 4.98 V
       #3 - 14.79 V
       #4 - 14.79 V
       #5 - 0 V
       #6 - 3.75 V

Pai pare totul perfect in regula, si alimentarea de 5V si cea de 12V si masa, si CAN-ul... Ramane ECU suspect pana la urma :(

pai cum spuneam... am trimis ECU de pe masina la BBA-Reman Anglia http://www.bba-reman.com/nl/index.aspx si zic ca e bun.

Acum ramine sa fac cum zicea colegul CristiXP, sa pun celalalt ECU care a fost clonat (dar motorul nu merge bine cu el) si sa vad ce erori da.

Trebuie sa imi instalez din nou VIDA pe calculator.

Buna ziua.

Ieri am pus cel de-al 2 lea ECU clonat si au aparut si erori comune cu cel original. Deci cred ca nu e ECU de vina.

Am pus la loc ECU original si am codurile de eroare:

Ai identificat firele de CAN? Ai pus aparatul intre ele? Ti-am sugerat sa verifici tensiunea intre 5 si 6 si sa vezi daca sunt impletite intre ele

Nu am reusit sa inteleg/depistez care sint firele de CAN.

Dar cum adica .... si sa vezi daca sunt impletite intre ele ?

Am masurat ce mi-ai spus.

Bateria contact pus 11.75 V

bypass valve

pin #4 + # 5 ---- 11.71 V

pin #5 + # 6 ---- 0 V

inlet valve

pin #4 + # 5 ---- 2.78 V

Desfaci putin copexul sau banda izoliera de dupa mufa pana ajungi la fire. Firele de can, de obicei au aceleasi culori (ex: verde si verde cu alb) si sunt rasucite intre ele. Trebuie luat wiring diagram la mana si vazut ce module sunt pe magistrala respectiva de can. Poti sa ai un alt modul in scurt si sa-ti dea magistrala peste cap. Le deconectezi pe toate si apoi le conectezi pe rand, citind codurile de eroare dupa fiecare modul rconectat. Vezi ce erori apar si ce erori dispar dupa fiecare conectare a unui modul

Am desfacut firele din spatele mufelor de la supape si fiecare mufa are alte culori diferite si nu sint rasucite intre ele. singurele fire rasucite intre ele am vazut cele care sint pe motor, cred ca vin de la injectoare.
