Rather than just throwing these away, flog them on fleabay, you might make a bob-or-twothe black box contains two relays used by the ABS system - the relay that provides the +ve feed to the two actuator solenoids, and the on/off relay for the ABS pump.
To be honest i don't think there's a high failure rate as there not worth much secondhand with abs its probably wheel sensor that are the weak link.does anybody buy the ABS units for these? thought most people would just scrap the ABS if it failed?
