GF54.21-P-4106-01GK Extended Activity Module, Task

The main tasks of the extended-activity module (EAM) (N10/1) are as follows:
- Controlling the door courtesy lights
- Disabling mirror dimming
- Controlling the headlamp cleaning system (HCS)
- Controlling the rear window heater (valid up to 31.08.01)
- Controlling the heated seats
- Supplying power to the sliding/tilting roof (SR) or lamella roof switch via the convenience feature (valid up to 31.08.01)
- Controlling the PTC heater booster (R22/3) (valid up to 31.08.01)
- Controlling the auxiliary fan (M4)
- Scanning the cruise control pushbutton switch (S40) and relaying this data to the control module (DAS, N73/1)

New features as of 01.09.01
- Controlling windshield wiper speed 1 or 2
- Actuating the automatic headlamp range adjustment (AHRA)
- Actuating the left and right front headlamps
- Emergency light function for proper functioning of the low beam in the event of failure of the all-activity module (AAM) (N10) and CAN communications between the all-activity module (AAM) (N10) and the extended-activity module (EAM) (N10/1)

To perform these tasks the extended-activity module (AAM) (EAM) (N10/1) scans various signals and switches direct.

Over the engine compartment CAN the extended-activity module (EAM) (N10/1)exchanges data with other control modules.

Diagnosis
Diagnosis is performed with the STAR Diagnosis tool. For this purpose, the extended-activity module (EAM) (N10/1) has a dedicated diagnostic line.

This line is also used for diagnosing the all-activity module (AAM) N10), the transfer case control module (N78) and, as of 1.9.00, the trip computer (TRIP) control module (N41).

The extended-activity module (EAM) (N10/1) is linked with the all-activity module (AAM) (N10) over the engine compartment CAN.

When terminal 15 is off, the CAN (N10 - N10/1) is responsible for communications between the all-activity module (AAM) (N10) and the extended-activity module (EAM) (N10/1).

The CAN (N10 - N10/1) is a standalone CAN link between the all-activity module (AAM) (N10) and the extended-activity module (EAM) (N10/1). No other control modules are connected to the CAN (N10 - N10/1).
