Should the function of the front passenger seat occupancy recognition system or the passenger side airbag indicator lamp be affected, the risk of injury for passengers in the event of a crash would be increased. Should the function of the instrument cluster and the windshield wipers be affected, the risk of a crash would be increased.
Remedy
