Topic vechi, problema actuala
Focus 1,8 benzina 2000, model 2001.
Probleme ale masinii:
1) inchiderea centralizata mai merge si mai nu merge => am dat din abundenta cu WD40 in incuietori pe toate partile la cele din usile fata si cel putin azi a mers ulterior continuu si fara nici o problema inchiderea centralizata
2) se intampla in mers sa : + cada pur si simplu acul de la kilometraj (nici nu inregistreaza din acel moment distanta parcursa+intreg restul bordului functioneaza, inclusiv turometru, resetare distanta parcursa, becuri, etc)
+ ulterior cand incetinesti si o pui pe liber cand ii scade viteza moare motorul. Ii dai cheie si porneste imediat.
+ Nu intotdeauna cand cade acul de la vitezometru se si opreste la incetinire
I-am facut o diagnoza cu FORScan:
- eroare pe modulul ABS de comunicare - am sters si a disparut, nu a mai reaparut
- eroare pe CSM B2159 - am sters si a ramas in continuare, nu dispare.
Am rulat alte teste din FORScan, toate au iesit ok.
Pareri ceva? Help!
M-ar interesa partea cu acul vitezometrului si a opririi sa o rezolv cumva...
Cautand pe net, am dat de topicuri care ba zic ca B2159 ar avea legatura cu inchiderea centralizata, fire ceva intrerupte la modulul confort (destul de intuitiv) si altii care spun ca ar fi legat de ECU si ca ar exista o siguranta de 3A pe undeva si daca acea siguranta e arsa inseamna ca ECU trebuie inlocuit...dar asta am vazut la cei la care nu le porneste masina si au aceasta eroare printre altele.
$1 scrie:$2 have seen were water in the ECU can throw the B2159, there is a 3 amp fuse in the fuse box .this is the memory for the engine control unit.check to see if this has blown. If the fuse is blown the ECU needs to be replaced.
I would start with this problem more then likely it is what is causing the stalling if you do not keep it running
$1 scrie:$2rom the research I have done the fault lies with the connection from pin 14 (white wire) of the green connector from the CSM to pin 15/11 of the fuse box under the glove box (there's about 6 connectors that go to it, I can't remember off-hand which colour one it is). This connection then finally goes to pin 26 of the Central Timer Module (CTM) which is located on the reverse of the fuse panel (along with fuse 63).
I think the 'short to ground' bit is misleading as if I read codes off the CSM on the bench with nothing connected I get the code B2159. If I apply 12V to pin 14 of the CSM the code goes away. So I suspect that 'short to ground' can be shown even if it's just an open circuit, the CSM must expect pin 14 to be normally high (12V).
My plan of attack next is to run a separate wire from the CSM to the fuse panel hoping that it might just be a break somewhere in the loom. There's also a possibility that the connection between the front of the fuse panel and the CTM is damaged or that the CTM itself is faulty.
