The Eberspächer Airtronic D2 12V Control Unit (ECU) is the main electronic module responsible for managing all operating functions of the diesel air heater system. It controls fuel dosing, ignition, blower motor operation, safety sensors, and fault diagnostics to ensure safe and efficient heater performance. A faulty control unit may cause the heater to stop operating or function unsafely; replacing it restores stable, reliable, and efficient operation.
