Task

Actuating the heater water circulation pump
The front coolant circulation pump is actuated by the right front SAM control module upon request from the AAC control and operating module (N22) (N10/7). The right front SAM control module (N10/7) reports back the status to the AAC control and operating module (N22). Under certain operating conditions switching on the coolant circulation pump is requested by the AAC control and operating module(N22) even when the ignition is switched off (e. g. engine residual heat utilization).
