ABS brakes are a complex but valuable asset to the Corvette driver. As with many complex systems, they require some attention from time to time. The system is designed to give the driver notice that it's working properly. A whirring sound accompanied by a pulsation of the brake pedal are typical signs that the system is working as it should. If these events aren't noticed, there's a systematic solution to troubleshooting the ABS that can be done in the driveway by the most novice of mechanics. Follow along as we diagnose ABS.

If you have an intermittent problem with your ABS, check your module relay by tapping it to see if it's sticking. As complex as this system is, Chris Petris reports that he has had to replace only one module in all his years of working on Corvettes. He says the reason for the failure is the car was repeatedly jump-started, and he believes the cables may have been crossed at some time. With that in mind, these tests should identify any problem you'd typically find with your ABS brakes.

Considering that the purchase price of a test light and the necessary relays is cheaper than the cost of a technician to find the problem, it makes perfect sense to arm yourself with this information and strengthen your wallet, as well as your ABS.
