Condition

Fig 1: Identifying Oil Level Sensor

Courtesy of VOLVO CARS OF NORTH AMERICA.

The engine control module (ECM) checks the signal from the oil level sensor. Diagnostic trouble code (DTC) ECM-5630 is stored if the engine control module (ECM) registers that the oil level signal from the oil level sensor is outside its normal operating range. ECM-5630 (signal too high, signal too low) is diagnosed while the engine is running. ECM-5630 (faulty signal) is diagnosed after a number of different criteria (engine speed (RPM), vehicle speed, etc.) have been reached.
