The EAM (2) is the solid state control module in the eCall system and is located in the center of the instrument panel behind the Integrated Center Stack (ICS).
The EAM (2) is connected to the instrument panel wiring harness using one 32-pin wiring harness connector (5) and three antenna connectors (4). The Universal Serial Bus (USB) and fourth antenna connector (3) are not used at this time. The module is mounted to the instrument panel structural support using four bolts at each of the four mounting bosses (1).
The EAM has an internal cell phone antenna which is used in the event of the vehicle's cell phone module not operating or not operating properly.
The EAM incorporates a backup battery (2) with a life expectancy of 5-7 years that will allow the eCall system to continue to work in case of vehicle power interruption. The battery will allow call and data transfer for at least 15 minutes with callback capability for at least one hour after a vehicle emergency.
