Signal output for RTI (road traffic information) (Japan only)
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Volvo V70, 2006 Volvo V70, 2005 Volvo V70, 2004 Volvo V70, and 2003 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
The road and traffic information system, RTI in Japan, uses directly connected input signals from the accessory electronic module (AEM) (4/78) for processing of information.
The accessory electronic module (AEM) sends four signals to the RTI-system. Two of the signals are display lighting and reverse gear signal to the navigation unit, and the third is a speed signal. The fourth signal is a relay control for voltage supply.
The brightness of the display lighting, vehicle speed signal, and the reverse gear signal comes from the central electronic module (CEM) (4/56) via the CAN-net.
