Firing the "parts cannon" at an active ABS wheel speed sensor code often results in misdiagnosis and an unhappy customer. It may start with the wheel bearing hub unit or wheel speed sensor. If those parts do not resolve the problem, the technician may fire the parts cannon at the ABS hydraulic control module. Typically, the customer's patience and wallet runs out before the car is fixed.
