Body Control Module: Description and Operation
GF54.21-P-4100-02GK All-Activity Module, Task
GF54.21-P-4100-02GK All-Activity Module, Task
-
as of 1.12.99
The main tasks of the all-activity module (AAM) (N10) are as follows:
-
Controlling emergency opening via the central locking system when a crash is detected by the restraint systems control module (N2/7) with
warning lamps flashing and interior lights on
-
Controlling the wiper system
-
Controlling the central locking (CL) system
-
Controlling the anti-theft alarm system (ATA)
-
Controlling the interior lights
-
Controlling the radio frequency locking (RFL) system and receiving the associated radio signals
-
Controlling the automatic lowering of the power windows (valid up to 31.08.01)
-
Convenience control of the tilting/sliding or lamella roof together with the extended-activity module (EAM, N10/1), allowing actuation without
terminal 15 ON
-
Convenience control for the power windows, allowing actuation without terminal 15 ON
-
Convenience control of seat adjustment, allowing actuation without terminal 15 ON
-
Controlling the air conditioning (valid up to 31.08.01)
-
Controlling the stationary heater (valid up to 31.08.01)
-
Interrogating the rain sensor (B38) (valid up to 31.08.01)
-
Actuating the turn signal lamps
-
Controlling the exterior lights
-
Trailer recognition
-
Actuating the fanfare horns
New features as of 01.09.01
-
Controlling the automatically heated outside mirror in relation to the outside temperature
-
If alarm is active -> signal to E-Call ((USA) only)
-
Interrogating the rain and light sensor (B38/2)
-
Controlling the air conditioner recirculation relay
-
Convenience control of the sliding/tilting roof, allowing actuation without terminal 15 ON
To perform these tasks the all-activity module (AAM) (N10) scans various signals and switches direct.
Over the engine compartment CAN all-activity module (AAM) the (N10) exchanges data with other control modules.
Diagnosis
The all-activity module (AAM) (N10) is diagnosed by means of the Star Diagnosis tool.
Since the all-activity module (AAM) (N10) has no dedicated diagnostic line of its own, it is diagnosed over the diagnostic line of the extended-activity
module (N10/1).
The CAN (N10 - N10/1) is a stand alone CAN link between the all-activity module (AAM) (N10) extended-activity and the module (EAM) (N10/1). No
other control modules are connected to the CAN (N10 - N10/1).
