I have been surching the net for days looking for someone who's had the exact same problems.
Found lots of similar ones but not sure if there the same

When i got the firstBreak system failure message i drove the car home and turned it off then back on again started fine and message went away.
a week or so passed and i came up again so i though good enough, pulled over to the side of the road turned car off but would not start after tying for about 20min i got it towed to a machanic.
the next day he got the car started got the same break message and then also the Transmission service required message, when he turned car off would not restart for an hour or so. and now also i've noteced when you try to restat there is a clicking noise coming from right under the shifter sounds like a solinoid clicking and the battery light flashes,
also you can not turn off the SRS while these messages a dissplayed

No one including the dealer have heard of all these symptoms coming at the same time
just wondering if you think it might be the ABS Module or Maybe Low Volterage?

Any imput would be helpfull

 

Not sure if this is helpful but when i ran my battery flat the other day, the car wouldn't turn over at all but the "Brake Failure" message appeared with the key ON. I already had the transmission service message. Brake message went away as soon as i was recharged. So yes, it may be low voltage.

 

I justgot my car backafter my machanic had it for a week and couldn't find out what was wrong.
drove it home with transmission service required on / drove fine when i got home i turned it off and restarted it fine no lights , and restarted 10 times fine.
I checked the transmission fluid and it wasa liter low added it seems fine
I wonder if the stretch of wet wet wether we were having when this all occured had anything to do with it and maybe it messages wouldn't clear till i took the car for a drive and got up to speed?

any input or ideas would be welcome
Thanks!

 

Very possible the ABS module is making the car do this.

 

i just got word back from the volvo dealer and that's the conclusion
module only costs $450.00 canadian new
we will see!

 

You can have it rebuilt for alot less than that.
Check with this guy.

after i drove another 3 hours to pick my car up, about half way home and guess what? the lights came back on nothing fixed at all $850.00 or so
then i turn around and leave it there for another week. they do some wire tracing and find a loose wire problem fixed 360.00 and then just before i'm ready to go pick it up i call them . YOU guessed it light's came back on , now there saying it's got to be the ECM but NO FING GUARANTEEEEEEEE



WHAT the hell am i supose to do this is ****ing crazy it's gonna cost me 2-3 gand to get a damb break light turned off what a peace of **** .

 

Are you sure they replaced your ABS module?? Mine went on my 1999 S80 and I was given the same price by 3 diffrent dealers here in Ontario.. $980.20 + Taxes.
$450.00 seems awfully cheap.
I got a rebuilt one from ABSmodules.ca for $189.00 and installed it myself.

They have toll free number for Canada & USA

 

Sounds to me like someone doesn't know what they are doing working on the car.

 

FYI, mine had --- Brake/Engine/STD lights on intermittingly. I follow the link Tech provided above and solved the problems. It was the ABS/STD module. It cost me about $150 including shipping. However, it takes a about a week including shipping time to get it back on your car.

 

I had the same codes & replaced my ABS module back in 2008 & all has been fine until recently I gave a guy a boost & hit held both terminals together & I think he fried my ABS module, just put in another one today but the only message that doesnt go away is Transmission Service Required or something like that. Im gonna have AAMCO read the code & see oh yes it also has the check engine light on
