ABS light and brake warning light were on. Odometer did not work. I replaced ABS control module with an used one and fixed problem.
ABS light is on. Dealer suggests replacement at $1600.
Brake & ABS light is on very often.

ABS light has begun flickering.
abs light
happening intermittingly not sure its the module .mech say the front pas side sensor kicks in and out says it could be electrical
ABS Service light and engine system maintenance come on alternating, although neither are real problems. Not sorted out yet.
ABS, brake warning light and "brake failure" notification stays on. No traction control/awd. Dealership is quoting $1600 to repair.
ABS light went on. Dealer said the ABS module needed to be replaced. I had an independent repair shop replace it with a used one. That shop took it to the dealership to have the codes cleared which fried the whole computer system. That had to be replaced as well. In the end I ended up paying over $3000 for the entire thing!
ABS warning light comes up.
The ABS brake light came on. After research, I learned it was better to have it rebuild, so I had it taken out & I sent it to a reputable place. It came back was reinstalled. After a week, the light came on again.
Had it taken out, sent it back. Put back in, light came on after 2 days. I just don't what to do from here. I read modulemaster is the best, but that don the work on a 2004 CX70 Volvo.
the warning light stays on. ABS brakes. No cruise control. I am investigating places on the web that rebuild the modular. It doesn't look like it would be too hard to remove & replace. It would be sure be cheaper then the $1,100 a Volvo mechanic quoted me. My only problem is determining if the modular is a K20 or a K25, there was a difference in the quote. after reading some forums, it could be the SAS as well.
