A failsafe system for a skid control system for a multi-axle wheeled vehicle. The skid control system has a plurality of skid control modules, each of which is operatively associated with one of the axles of the vehicle and the skid control modules are operatively coupled by wiring on the vehicle. Each skid control module comprises a skid control circuit for skid controlling the wheels of the associated axle, which circuit is supplied from an electrical power source such as the vehicle battery, either regulated or unregulated. A failsafe circuit is provided in each skid control module and the failsafe circuits of the several modules are connected in cascade fashion to form a chain. An input signal is supplied to the input of the first of the cascaded failsafe circuits and can propagate through the chain of failsafe circuits to the output of the last failsafe circuit only if wiring connecting the modules is proper, the failsafe circuits themselves are operating properly, and electrical power is supplied to each module. A warning occurs when the signal fails to propagate through all the failsafe circuits, and this indicates loss of power or a fault in the modules or the wiring connecting the modules. |
