ABSTRACT:
An anti-lock braking system comprises a pump motor which is energized initially during vehicle drive-off and then deactivated. The deactivation voltage and subsequent motor voltages are evaluated against predetermined voltage levels for an appropriately operating pump motor to determine whether or not the anti-lock braking system should be deactivated and a failure warning mechanism activated to warn the vehicle operator of the deactivated system.
