volvo v70 do not part with the ignition switched off

[saetta]

hello, the car in question is a volvo v70 year 19.12.2000 displacement 2435 125 kw engine b5244s.

the customer complains that the machine doesn't start ,we checked the battery that I showed 12.11 volts I have tried changing the battery with a longer charge, however, the picture will not turn the same and the starter motor does not turn,you hear something in the motor that is powered and just.wandering on the web I've seen that with power low battery the control unit cem and the engine control unit, lose the sincronizzazzione do you think it is possible to restore the operation? I put the code of the control unit cem 9452552 and the HW PN9452553.


thank you for your attention.

I know that there is a program of the codecard that synchronize the ecu and the cem, (always the problem is with that) however, I did a tour on the website of the codecard and are not able to find it, I know that it exists since I have one version but unfortunately is not active, I put a screen in a way that if you have to look for you know, at least as it is the page of the program and the version number

hello, I have the impression that there is any problem on the can network or the control unit cem.
if you accents the painting in the engine is powering something.then in the evening he turned off the car and in the morning is no longer a game.

I tried to zoom in on the image because that is no good

hello sisco, thanks for the help, unfortunately I can not read attachments.now I try to see it on the website of the codecard is a site in italy or abroad?

[sisco]

I'm sorry I can not make the image sharper, I don't know what it may be, however, even if cem always you have to sync it with the ecu the engine to put in motion (at least I think)

[sisco]

if you are looking for it in the internet codecard.the eu, as I told you, I tried but nothing, but I'm sure that is a their program, just now I tried to activate it, and when I click on the paypal to go ahead with the procedure it tells me software not supported, you probably can't manage more, I do not know

[saetta]

ok thanks for the info,if it was a problem of sincronizzazzione between the two ecu could do not to turn on the instrument panel? the cause may be the battery?

[sisco]

have you checked all the fuses? you have a wiring diagram to be able to carry out the checks?
