The SKREEM contains an RF transceiver and a microprocessor. The SKREEM transmits RF signals to and receives
RF signals from the ignition key transponder through a tuned Sentry Key Antenna Ring that is wired to the
SKREEM. If the Sentry Key Antenna Ring is not mounted properly around the ignition lock cylinder housing, communication
problems between the SKREEM and the ignition key may arise. These communication problems will
result in ignition key transponder-related faults. The SKREEM also communicates over the Controller Area Network
(CAN) data bus with the Powertrain Control Module (PCM), the Instrument Cluster, the Body Control Module (BCM),
