Alarm Signal Outputs

An after market alarm unit can be connected to the accessory electronic module (AEM). The system consists of four output signals which can be used as input signals in the external alarm system via a cable harness. The accessory electronic module (AEM) uses the existing Controller area network (CAN) to receive/forward signals for the vehicle alarm, key and door status.

When installing an after market alarm system the vehicle must be configured using new software. Configuration is carried out via VIDA (Volvo scan tool).

There are diagnostics for the alarm signal outputs.
