GF82.95-P-2007QJ Switching E-CALL On/Off, Function
- with CODE (349) E Call emergency call system
- with CODE (498) Japanese version

Switch on characteristics:
The emergency-call system is switched on by turning the key in the electronic ignition switch control module (N73) to the "circuit 15R ON" position. The switch-on procedure is indicated by the indicator lamp flashing (5 seconds) in the SOS pushbutton switch (S93/3). The system is ready for operation.

After switch on the transceiver unit integrated into the E-call control module (A35/8) is activated. Parallel to this it awaits a ready confirmation from the restraint systems control module (N2/7).

If the system is not authorized, an error message appears in the instrument cluster and the system is not operational.

Switch-off characteristics:
^ emergency-call is switched off at "circuit 15R OFF" with a delay of 10 min., if when doing so an alarm call is not active and the CTEL is not set to an extended shut-off delay period.
^ For control of the telephone system the emergency call also remains active during the telephone shut-off delay period, but it is not possible to trigger an emergency call.
^ During an emergency call, Emergency-Call is only switched off when the emergency call is terminated.
^ If an authorization is at that moment taking place in transmitter key position (A8/1) "circuit 15c", then this is so terminated and Emergency-Call is then switched off

When COMAND and "circuit 15c" are switched on, it is possible to telephone within the adjusted shut-off delay period.

State display, function
The state display in the SOS pushbutton switch (S93/3) serves to check the functioning of the Emergency-Call system.
Every time the E-call system is switched on, the state display comes on for approx. 5 seconds and signals the readiness of E-call. Then the state display goes out.

If an Emergency-Call is triggered, the state display starts to flash (0.5 seconds on, 0.5 seconds off, etc.). If no Emergency-Call could be transmitted, the state display comes on. If data is transmitted, the state display returns to the same status as before the emergency call actuation.
When the E-Call system is in diagnostic mode, the state display also starts to flash (1 second ON, 1 second OFF, ...). An E-Call system error is present when the state display does not go out 5 seconds after switching on or if it comes on at a later stage.

Possible reasons for the status display lighting up
External errors:
^ Tilting cone sensor (B66) defective
^ Power supply too low
^ No or incorrect SIM card installed
^ Communication with the restraint systems control module (N2/7) interrupted
^ Communication with ESP and BAS control module (N47-5) faulty
^ Fault in SOS pushbutton switch (S93/3)
^ Fault in GPS reception (antenna system)
^ Faulty reception with TELE AID backup antenna (A2/50) or CTEL antenna (A2/22)

Internal errors
^ GPS receiver defective
^ Vehicle is not authorized or is in the process of being authorized
^ Memory defect on E-Call control module (A35/8)
^ The PIN (Personal Identification Number) has not been stored in the E-call control module (A35/8) by the user (e.g. after changing PIN number)
^ Integral transmitter/receiver unit of the telephone is defective in the E-Call control module (A35/8)

The E-call control module (A35/8) can be coded by means of STAR Diagnosis so that state display does not light up despite a lack of authorization (all other system faults are displayed in spite of this). The dealer should have the customer confirm deactivation of the state display in writing using a preprinted form.
