ABS light on. Brake light popped on, mileage & speedometer quit. then Check engine light turned on.
ABS module failed twice under warranty. When it failed again I could not afford to have it replaced by the dealer. I was about to take out the module and send it out to be repaired (bad connections are soldered)to a guy in Michigan when I found a quick fix on the net. You put a wedge (I used half of a wooden clothes pin) between the ABS wiring connector box and the pump housing. The ABS light and the TRACS light go out after you drive a bit. Best of all, the ABS brake system works again ! Look it up on the web

hi my volvo s 70 the problems start by the check engine light on iven reset by dealer,then the ABS light ,and one day in few weeks ago,the speedometer stop working and the orange light arrow start on,and blanking ,it was scary .i just drive my car with not taking attention to all this light on sometime all light off NICE!!!!! but i just wondering when thise lights turn crazy again.
ABS Light and Brake Light came on, on the dash. Speedometer stopped working when they were on. Would only happen intermittently, when they were not on, the "wet weather" light would flash, and put the car in a low gear occasionally. Used the Half a Clothespin trick mentioned in this forum and it worked PERFECTLY!!
Still working on it. ABS light come on, the speedometer drops to '0', and I have to shift manually if I have to go from a stopped position. Then, it will eventually correct itself for a day, then happen again. Need to take it in to get it fixed but I'm afraid of the cost...also having issues with ATM.
Going 60 MPH the speedometer plummeted, brake lights and check engine lights came on.
Easy to replace the module... send it in to a rebuilder for less than $150.00 do it yourself. I did it at 234,000 miles, and now have 280,000 miles on it. Everything has been perfect since the repair.

If you have a later model, or if the module didn't fix the problem, check the front CV Joints. When they go bad, the axle sensors don't read properly. Changing the front axles fixed my 2002 XC70!
ABS,TRAX AND CHECK ENGINE LIGHTS APPEAR. TRANSMISSION SLIPPING. I WAS TOLD BY MANY INDEPENDENT AGENTS AND MACHANICS THAT TRANee NEED TO BE REPLACE. (I have driven the car for about 25,000 to 30,000 miles with the problem). finally I must replace the tranee.
When the temp drops lower than 32 the abs light comes on and goes off when it warms up. Trying to keep it another year to break even with repair cost. Won't buy another Volvo because of Volvo dealership repair theft. Great car!!!!! Would keep it forever if I wasn't afraid of repair cost.
My mothers 2000 s70 abs light always been on and shift light for a while but all of a sudden transmition started to slip and not go into gear and when I pull up theincline of drive way it slipps , and it was intermittently but now it is frequent and also car wont start all the warning light service lights in the dash are on and no speedometer and no odometer everything is whacked
ABS and traction control issue
noise when I turn front end and go over bumps.
I have the same problem as described: a "brake failure, stop asap" message and the brake and abs lights display. I went to an authorized volvo center and they said it would cost 1257.00 GBP ($2000.00) My V70 is a British spec vehicle.
Fixed! thanx for the info, one credit card and problems are all gone, traction control, ABS, engine light, odometer now works! No more messages!
all lights are out on speedomer,clock, gas....
Same issue - no resolution yet.
same problem, no solution as of yet.
I send it to one of the repairs shops $ 140.00 as soon
the weather got warm failed again,found one in a you-pull it junk yard $15.00 still working.
"brake failure, stop asap", abs service required, "break (light)","abs (light)"comes and goes intermitently. Worse on
hot days or after traveling on bumpy roadways. very annoying.
