Front Overhead Console

G11294125
ITEM DESCRIPTION
1 Telematics speaker (All markets except Russia)
2 Breakdown call (bCall) switch
3 Emergency call (eCall) switch
4 Microphone

The front overhead console houses the Breakdown call (bCall) and Emergency call (eCall) switches, microphone and telematics speaker. The functions of the bCall and eCall switches are controlled by the telematics control module.

NOTE: The telematics speaker is located in the overhead console in all markets except Russia. Russia markets have a telematics speaker located in the top of the instrument panel.

A diagnostic line (BTN), between the front overhead console and the telematics control module, enables the system to check the harness wiring is connected and the interface is functioning correctly. In operation, the telematics control module briefly pulls the diagnostic line (BTN) to ground, allowing the telematics control module to detect the circuit completion.

The microphone input is shared by the telematics control module and the Infotainment Master Controller (IMC). Data from the microphone is received by the IMC. The IMC passes the data, via the Gateway Module (GWM), to the telematics control module on the High Speed (HS) Controller Area Network (CAN) powertrain systems bus.

A 55 mm telematics speaker is located in the overhead console and is used in all markets except for Russia. Russia market vehicles have a dedicated 80 mm speaker located centrally in the top of the instrument panel.

Light Emitting Diode (LED) lamps, integrated into the eCall and bCall switches, provide switch illumination and indicate the status of the call operation.

The following illustration shows the LED lamp status for the eCall and bCall switches during normal use.
