Fault forwarding is a maintenance technique which is used to decrease the time taken to repair a vehicle.
Thus minimizing the time taken to return the vehicle to service.
The racecar is often highly instrumented and has a telemetry link back to the pit crew.
This technique is also sometimes used by airlines to try to reduce the impact of unscheduled maintenance to their schedule.
Problems are sent to the airline operations center through the ACARS link.
