Airbag light came on. Computer read the wiring harness was faulty and had to be replaced. The consumer states that the air bag light had come on. The manual indicates that the vehicle must be serviced immediately. When the vehicle was serviced, the service writer made it clear that this is a common problem. The factory harness indicates there is a problem with the head rest air bag only. (there isn't one) now the consumer is forced to replace the factory wire harness with a re-engineered harness that sends the computer the proper information.
