The inventive mechanism detects wire stuck-at faults, which can be used with any other ECC code. The inventive mechanism determines the number of 1's (or 0's) in the data portion and the ECC code of the data portion. This counted number is then provided with ECC code. The data portion, its ECC, the counted number, and its ECC are transmitted to the destination. At the destination, the message is decoded, and the number of 1's in the received message is compared with the counted number, if there is a discrepancy, then a wire fault is signaled. The mechanism may also detect any number of faults provided the number of 0 to 1 transitions is not the same as the number of 1 to 0 transitions. The mechanism can be reconfigured to work with any transmission wire width.
