Five problems related to brake abs warning light have been reported for the 1998 Volvo V70. The most recently reported issues are listed below.
Prior to dealer visit for 60,000 mile service, the abs and tracs lights began coming on periodically. Dealer checked and found codes abs-314 & 324 set in system. Dealer stated that module replacement would cost approximately $675. Dealer said that although the lights indicated loss of abs, braking ability should not be compromised. At that time I declined the repair. Since that service visit, the lights have continued to go on and off periodically; on several occasions, it occured during braking and it felt as though the brakes were not going to grab appropriately, if only momentarily. I am now wondering if this is a safe condition, especially with the onset of winter driving. When I saw the number of other complaints on the same issue at the NHTSA website, I decided I should include my own. My suggestions for remediation range from: 1) have the manufacturer investigate the issue further, 2) have the manufacturer replace all modules that are reported to have this problem, or 3) at least have the manufacturer assist the customer by paying a portion of the replacement cost.
Anti lock brakes control unit failed. A light indicated that the abs brakes were not working, but the consumer heard and felt the abs brakes were working when applying the brakes.

When the brakes were applied, the abs light appeared on the dashboard. Braking power hesitated, which caused the to have no brakes. The brakes activated without driver application. Yet, when the brakes were applied, there was a delay in braking.
Abs control module is cracked. I have heard this is a common problem for this vehicle. Abs system is not operable until ecu is replaced. Intermittent problem (abs light comes on periodically). Dt.
