Anti-skid service required......still!!!

[Mattttt]

Evening all,

2004 V70 D5

Sorry if your fed up with me, i know i am 🤣 changed the AYC sensor still have the error, VIDA says bcm and ecm faults, google says most common fault is SAS, im nearly at my wit's end, any help at all appreciated, i calibrated the SAS and got the green light the ABS fault goes away after maybe a minute, had the bcm repaired, only want the light off for the MOT

And what fault is vida giving you now?

BCM faulty signal
BCM communication with abs faulty signal

If its any consolation we are suffering the same prob with anti skid service required and brake failure stop safely warnings along with other odd behaviour on our 55 v50 2.0d (the Folvo) it's been narrowed down to the Ecm, abs module, or swm/clock spring via 2 different diagnostic checks, all of which will require a re-mortgage of your house to fix.
I called in to see Barry at Lakes to see what tmy options are and in his opinion with 40yrs of volvo experience the car has run its time.
Which is a shame.

Noooooo!!!! Thats so said, i want mine to last me a few years if possible 😬, I don't know of any specialists local to me

where did you get the new BCM and AYC sensors from
were they new or salvaged

do either of them need programming in (maybe the BCM, probably not the AYC)

what light is it you're trying to get rid of, is it showing up an EML or something

stupidest question of all but I don't suppose you've tried the classic battery off for an hour and on again now they've been replaced?

failing that hopefully someone who knows the technicals of it can come along and advise next steps

BCM is car original just repaired
AYC is salvage
The light is the anti skid one flashing and a message saying anti-skid service required thinks thats it, lol, not done battery off for an hour no 10mins maybe

Funny you should say that about the battery.
The guy at Lakes said to try it leave it off overnight and reconnect it via the set procedure, it's a crude way to reset the ECM
He also advised not suitable to do this on all models as it causes loss of some codes or other but the v50 is ok

[stuart bowes]

I've done it a number of times on mine, it does reset everything but obviously if a part is faulty the message will just come back straight away.. still it's a quick cheap easy thing to try

except for the agro of digging into the depths of the boot area, and having to lock all the doors by hand, and not being able to lock the tailgate

It seems to me the difference is, when you use VIDA to clear faults it comes up with that message, turn on, turn off, rev, do a little dance, make a little love get down tonight, which I've never really done. whereas the battery may be a proper complete reset?

I assume by 'set procedure' he meant having key in position 2 so the headlights coming on absorbs any jolts which could in theory damage the various modules? or something like that

[Simmy]

if the abs has stored a hard code it will need a specialist to clear it some codes cannot be reset with vida
