Alarm Signal Outputs
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.
An external (aftermarket) alarm unit can be connected to the accessory electronic module (AEM). The system consists of four output signals that via a cable harness can be used as input signals in the external alarm system. The accessory electronic module (AEM) uses the existing CAN-network to receive/transmit signals that describe the car's alarm, key, and door status.
When installing an after market alarm system the car must be configured using new software. Configuration is carried out via VIDA (Volvo scan tool).
There are diagnostics for the alarm signal outputs.
