Spare Wheel Auto-Locate
WARNING: This page is about a different car, the 2003 Chrysler 300M and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
If the spare tire is mounted on the vehicle, the EVIC will detect the relocation and determine from the sensor transmit intervals which wheels are mounted and which one is now the spare. The spare tire sensor/transmitter transmits once per hour. The sensor/transmitters in the mounted wheels transmit once per minute when the vehicle is moving at 25 MPH (40 KM/H).
