Brake Antilock Control Unit/module Problems of Volvo 850

Abs module failed. Looks like major dealer repair. This is a major component of the vehicle and should be treated as such and no longer treated as an accessory item. For these devices to be considered an "accessory" they should then be made as user replaceable which is not the case. Then again, is it a good idea to have every Sunday-mechanic replacing such a critical item? I have had an abs warning light for over two years now. Diagnostics say its the abs electronics. I do not have the budget or experience to replace it. Several websites point to failing or defective capacitors on the electronic module itself.

While applying the brakes the abs brake light appeared on the dashboard, and remained on. Following that the brake pedal went to the floor. This caused a loss of braking power. Consumer was able to maintain control of the vehicle and drove it home. Consumer contacted the dealer, and the mechanic determined that the abs modular unit needed replacement.

Hairline crack in circuit board on vehicle computer makes abs and tracs braking system inoperative. This is an intermittent problem and goes off if the vehicle is stopped and re-started. I talked to an independent Volvo repair shop and he indicated that he has replaced ten computer this year in boise, idaho this year on various Volvo models, years 1993 to 1998.

Intermittent failure of the abs control module.

Falure of abs control modual for 1997 Volvo 850 glt. There are a huge amout nof failures for 1996-1998 and should be a saftey recall.

I have a 1997 Volvo 850r that is currently experiencing problems with the abs/tracs system - the lights came on for the abs and the tracs system. In researching my problem it has become apparent that the 850 Volvo is known for failures to its abs module and the entire braking system in general. The amount of information that I have been able to find on this common problem leads me to believe that this should be a recalled item. Apparently Volvo now offers a new and improved abs control module (that they charge dearly for) because of the numerous problems and replacements of the old units. Volvo should bear the expense of replacing these units as it is a safety issue and the shear number of these instances leads me to believe that it is a systematic design flaw.

1997 Volvo 850. The abs and tracs lights are on approx. 90% of the time while driving vehicle. When lights are on, brake pedal is very soft and stopping distance is significantly increased. When lights are off, brake pedal gets firmer after pumping and braking distance is reduced. This problem has gotten progressively worse over the past 24 months. Dealer and independent mechanic were able to determine cause or correct the problem during repeated visits. Ineffective brakes and loss of steering control while braking contributed to a serious accident involving the vehicle and a semi-trailer.

I noticed an odd noise which sounded like something rolling around in the back of the car, but nothing was. At time of state inspection, I alerted the inspectors. They felt something bumping from within the gas tank. I disassembled the floor coverings and inspection ports for fuel pump and gauge sender. I removed the gauge sender and looked into the tank and observed a plastic bowl-like object surrounding the fuel pump. I rocked the car and this bowl would slosh against the pump. This object appears to be a baffle to reduce sloshing around the pump. It would seem that it was intended to be glued in place, but has broken loose. I suppose that this would eventually damage pump or tank. A new tank will cost close to $400 which I will now order. Additional problem is intermittent failure of anti-lock brake/tracs system module.

Defective abs module on 1997 Volvo 850 t5.

The abs control unit on my 1997 Volvo 850 has an internal short or loose connection as told by the dealership. If you do research into this matter on the internet or by calling the Volvo dealerships, you will find this problem occurs very frequently in these cars. When the abs light is on there is no anti-lock brakes, and this can cause the brakes to lock up during hard braking applications, and easily on moist or wet roads. As a major safety feature on these cars and especially a Volvo, who is known for their safe automobiles this control module fails very often and can cause an accident if brakes lock up in a panic stop.
