ALARM SIREN NOT WORKING
The siren is connected to the Alarm Node
The alarm node is operated and controlled by the Body Computer Node via the VAN CAR2 network. If there is a fault, the Body Computer Node detects and memorizes the causes of the malfunction.
The networks are on stand-by 30 mins after the engine is switched off. This makes it impossible to carry out the fault diagnosis. If a diagnostic session has to be opened, start up the engine to reawaken the networks.
