General

The ETC simplifies the process of payment on toll roads. It settles payment procedures automatically without the driver having to stop the car.

-----------------------------------------------------------------------------------------

Function sequence

To transmit and receive the data, the Electronic Toll Collection (ETC) antenna (A2/94) and the Electronic Toll Collection control unit (A50/3) are installed in the vehicle. The ETC control unit communicates via the ETC antenna with the toll cashier's section. For automatic payment, a special ETC card must be inserted into the control unit. All information concerning the user and the fees that have already been paid are stored on this card. On the vehicle, the control unit is connected to the COMAND controller unit via an RS-232C interface. The ETC also has voice output and visual output (pop-ups).

-----------------------------------------------------------------------------------------

The voice output is:

- ETC card read error

- ETC card not accepted

- ETC card reader error

- ETC gate communication error

- Detailed information about previous fee payments (if the UP or RPT button is pressed)

- Card not inserted

Visual output (pop-ups) on the display on the COMAND controller unit are:

- COMAND controller unit booted and no ETC card inserted ("Please insert ETC card into ETC unit, when using ETC")

- COMAND controller unit booted and ETC card inserted ("ETC is available. Please eject ETC card from ETC unit when you leave the vehicle for security.")

- Positive feedback from fee payment station ("Passing OK, Fee: xx.xx Yen")

- Negative feedback (no authorization) ("Please Stop")
