GF54.21-P-4110-01GK All Activity Module Function



GF54.21-P-4110-01GK All Activity Module Function
- as of 1.12.99

The electronics of the all-activity module (AAM, N10) scans a number of different input signals and evaluates them with a microprocessor.
CAN messages are also generated from these signals and relays and lamps are actuated directly via power drivers.

The all-activity module (AAM, N10) is linked with the extended activity module (EAM, N10/1) over the engine compartment CAN. When terminal 15 is OFF, this link is carried by the CAN (N10 - N10/1).

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