Cars with an accessory electronic module (AEM) (4/78) can have a remote start function for the heater. This allows the heater to be started using a pager. A stop or start signal is transmitted from the accessory electronic module (AEM) to the central electronic module (CEM) (4/56) to start or stop the heater (4/7). This function is available for both fuel driven and electrical heaters.
