VOLVO S80 PARKING BRAKE SERVICE LIGHT IS ON

SOURCE: parking brake is stuck on

need to get the truck on jack stands remove the wheels and if the truck has drums you maybe able to use some PB blast because the brake cables are rusted for the emergency brakes and at the same time you can check out the condition of your shoes or pads if you get any oil on the shoes or pads use brake cleaner to clean them off

05 LS, i also have the same problem, heater blowing hot and parking brake light coming on. i just read that the malfunction from the (dual coil water control valve) will cause a spike in the system an will set off the parking brake light. The dealer wanted $645 w/tax to install a new water control valve Ford Part # 2R8Z18495AA, YEAH RIGHT !!!! I found the part on line for $110 w/shipping, i am going to install my self. Its sits behind the radiator passenger side about 6" deep from the fender. very easy to get to , one bolt, one sensor needs detached and the 3 heater hoses that go to it need clamped off before replacing it. As far as the brake light i read that you have to get the brake re-calibrated by the dealer, I dont know yet. If you want the web address for the part let me know. i also posted where to find your code for your door access on a 05 LS. [email protected]

you have to fix the problem with ur brakes- first check the wiring ,connectors and connection clips to the abs sensors and modulator if looks ok than have truck scanned some auto stores such as auto zone / advanced auto do it for free the code will give u a start point towards fixing ur problem--visual inspection of brakes doesnt always show problem

SOURCE: parking brake and abs light stays on, service 4wd

check your fuses. check your fuses. check under the hood on the top row there will be a 60amp fuse i beleive its the second one from the right it controls the abs system its blown. your probably gonna need a new altenator.

having the same problem with my 1999 s80 2.9 . replaced the abs module twice and still get the brake failure warning. when the ignition key is turned there is a clicking sound from the center console beneath the shifter, then the brake failure warning, and the car will not start. (also after the last abs module replacement the car sometimes gets stuck in park).
