I love my 2000 s80 and i've fixed a few things on her, but she has been fine. Now when I corner moderately hard (not all she's got, but it happens then too) or hit the brakes where the nose will dive, the brake light comes on (not the parking brake) and the service brakes soon message comes on. As soon as the car either comes out of the corner or I let off the brakes, they both go away and it doesnt happen for normal driving, only when I get on it a little. My first thought was low brake fluid, that is not the case and it is full.

Second thought was the sensor in the master cylinder for calculatinglow fluidis shorting or getting an inacurate reading. Tech or others, what do you think? Before I go and buy a new sensor, am I on the right track. Can I test this sensor, I have a multimeter and I have access to vadis.

 

Possible it is the sensor. That is the only thing I know of that is connected to cornering.

 

Thanks tech, i'll look into it.

 

I wouldn't be surprise if it's the ABS/STD module acting up.

 

Is the problem with the module you are referring to a software issue or the actual unit?

 

Short in the unit.(actually a bad solder joint)

 

Is the module expensive to have replaced? My ABS and STC light comes on when I am driving on bumpy roads. The lights also come on when I am cornering. They reset themselves, but it's a pain in the neck. Any advice?

 

I would guess the module. Genuine Volvo part is kinda expensive, but I know there are aftermarket ones available.

 

You don't happen to have any part numbers, do you? I wouldn't mind replacing it, if it was something that I could handle. Do I need any special computers or any of that stuff that only the dealership garage would have?

 

Read info from this link. It is also where I got my module serviced. I mentioned that I'm on a forum and he knocked $10 off. I haven't seen any of those lights since I put it back. He has instruction for removing it when you email him. Also instruction for putting it back when you recieve it. A+ service. Since Tech previously post this link. I'm going to repost it here.
