V50 L5-2.4L VIN 39 B5244S7 (2005)
The left-hand control stalk controls the start timer for the parking heater (3/133). No other timer is required when setting the timer control. The control
stalk is directly connected to the steering wheel module (SWM) (3/254) which transmits a signal via the Controller area network (CAN) to the central
electronic module (CEM) (4/56), which in turn transmits the signal on to the accessory electronic module (AEM) (4/78) when the electrical heater is to
start.
The start timer functions on either the electrical or fuel driven parking heater. The accessory electronic module (AEM) is not involved when the fuel
driven parking heater is selected. The heater to be used is selected in the driver information module (DIM) (5/1).
Alarm signal outputs
Output signals from the accessory electronic module (AEM) (4/78) are used when installing an after market alarm unit. Access is available to signals
indicating:
-
alarm status
-
door status
-
key status.
In this case the accessory electronic module (AEM) functions as a port between the Controller area network (CAN) of the vehicle and the after market
alarm unit.
Tele-mute function for mobile telephones
