Circuit/System Description

When a transmitter is inserted into the transmitter pocket and the ignition mode is changed, the transponder embedded in the transmitter is energized by the exciter coils located directly below the transmitter pocket. The energized transponder transmits a signal that contains its unique value, which is received by the body control module (BCM). The BCM then compares this value to a value stored in memory. If the value is not correct, the BCM disables engine starting.
