Alarm Signal Outputs
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.
The alarm signal function is available as accessory for the accessory electronic module (AEM) for cars of later versions.
The difference in chassis numbers between the two versions is shown in the table.

(1) applies to cars manufactured in production plant 1.
(2) applies to cars manufactured in production plant 2.
Information regarding which production plant a car is manufactured in can be found in the VIN number. The seventh position from the right in the VIN specifies the production plant.
When installing an after market alarm system the car must be configured using new software. Configuration is carried out via VIDA.
There are diagnostics for the alarm signal outputs.
