The BCM supplies most of the information displayed by the CMTC/EVIC. Display information, except for the internal compass function, is received
over the PCI bus. The FCM supplies the ambient temperature sensor information via the PCI bus. The CMTC/EVIC sends and receives data over the
PCI bus, communicating with the BCM, PCM, FCM, and the Instrument Cluster. Tire Pressure Monitoring system information is received by the
EVIC in the form of radio transmissions. The tire pressure sensors are mounted to the vehicle wheels. For complete information, refer to the Tire
Pressure Monitoring system section in this publication.
