## NHTSA's summary

FALSE WARNINGS THAT THE FRONT PASSENGER SEAT IS OCCUPIED WITHOUT THE SEAT BELT BUCKLED. Acoustic and visual warnings indicate that the front passenger seat is occupied and the seat belt is not fastened, when the seat is actually unoccupied. If the situation is currently present, sit in the seat and move the seat to a different position then the POL \(Passenger Occupancy Light\) light will function correctly. In some cases the Air bag Warning Light was illuminated. Advanced Crash Safety Module \(ACSM\) fault "930A1C \- Front passenger seat occupancy detection transmitting fault \(moisture\)" is stored. 1. Electronics \(for example smart phones or laptops\) are connected to the USB charging port or cigarette lighter and placed on the seat. 2. The seat was wet \(e.g. very high humidity, spilled liquids or rain\). 3. Faulty plug connection to Evaluation Electronics CIS \(Capacitive Interior Sensing\). 4. Excessive spacing between seat mat sensor signal wires and their grounding shield sleeve. \* Drying the seat mat due to moisture. \* If there is no moisture, secure loose cables and install 2 cable ties \* If the 2 cables ties are already installed properly, replace the seat mat \* Statement added to SI \- do not replace the CIS electronics or the ACSM module for this siutation.
