Action in service

Unplug all components on the BSD with the exception of the oil condition sensor, clear diagnostic fault codes from the control module fault memory and then ignition off/on. If the diagnostic fault code is logged again this means that the oil condition sensor is defective.
Reconnect all of the remaining devices on the BSD one after the other, clear the control module fault memory, and then switch the ignition off/on, continuing until the defective component is found.
If the fault is not found, check the BSD.
If the fault appears sporadically then check all contacts on the BSD.
