1881708C93 Used International/Navistar MaxxForce 7 Engine Control Module (ECM) – SID903

This used International/Navistar 1881708C93 Engine Control Module (ECM) is associated with select MaxxForce 7 6.4L V8 diesel engine applications commonly found in IC Bus school buses and International medium-duty commercial trucks.

The 1881708C93 ECM is associated with the Continental/Siemens SID903 electronic engine management system, used in certain International/Navistar MaxxForce 7 diesel engine configurations.

The ECM serves as the engine’s electronic control center, managing critical operating functions including fuel injection, engine timing, sensor inputs, electronic diagnostics, emissions-related controls, and engine performance parameters.

This module is associated with several International/Navistar OEM numbers, including 1881708C92, 1881708C91, and 1871601C92, which can help customers identify a replacement for their original engine computer.

This ECM requires VIN-specific programming before installation. Programming must be performed by a dealer or qualified diesel repair facility equipped with the appropriate International/Navistar diagnostic and calibration equipment.

Important Compatibility Note: International used different ECM hardware versions and calibrations across the MaxxForce 7 engine family. Matching the engine model or EPA emissions year alone does not guarantee compatibility. Verify the original ECM part number, vehicle VIN, engine serial number, hardware identification, and calibration requirements before purchasing.
