Probleme ECU Motor BOSCH EDC17 CP02 320d E90


Recommended Posts

Buna seara tuturor. Astazi mi s-a intamplat ceva ciudat cu masina : am avut ECU motor scos pentru a citi cu K-tag softul "pe masa", dupa care mecanicul mi-a pus-o la loc.

Precizez ca INAINTE de a scoate ECU motor, a fost decuplata borna, a ramas asa pana am pus ECU inapoi, iar la final am pus inapoi borna.

Problema : am observat ca nu se opreste masina la semafor (start/stop nefunctional). Am conectat recent ISTA si mi-a dat multiple erori de comunicare cu diferite module (erori ce NU existau). Ca si exemplu :

MOSTSYS : No communication with headunit

No communication possible with: Electronic fuel pomp control module - ECU not responding .... totusi am reusit sa dau ECU TEST si sa citesc datele (de ex programming date, manufacturing date etc)

No communication possible with: MRS - Multiple restraint system K-CAN....tot am reusit sa fac ECU TEST si mi-au aparut datele

Dupa aceste erori (am incercat sa le sterg si nu se putea) am mai demontat borna cateva minute, dupa care in afara de aceste erori mai apareau si altele...nici cu CAS nu mai comunica, nici cu JBE, respectiv si la DDE imi aparea cu rosu si zicea ca nu poate comunica.

Interesant ar fi ca masina porneste si functioneaza corespunzator. Ce ziceti, de unde sa incep? Sigurante/releuri...verificat daca a pus mecanicul ECU motor bine la loc, mufe etc???

Orice idee mi-ar fi de ajutor. Multumesc anticipat!
