Information:

The Electronic Control Module (ECM) monitors the engine oil pressure. The following events are associated with low engine oil pressure:
Table 1
Diagnostic Codes for Low Engine Oil Pressure    
J1939 Code    Description    Information    
100-17     Engine Oil Pressure : Low - least severe     The ECM has been powered for at least 2 seconds.
The engine has been running for at least 10 seconds.
There are no diagnostic trouble codes for the oil pressure sensor.
There are no diagnostic trouble codes for the 5 VDC supply.
Refer to Illustration 1 for the trip point for the oil pressure.    
100-18     Engine Oil Pressure : Low - moderate severity     The ECM has been powered for at least 2 seconds.
The engine has been running for at least 10 seconds.
There are no diagnostic trouble codes for the oil pressure sensor.
There are no diagnostic trouble codes for the 5 VDC supply.
The engine will be derated.
Refer to Illustration 2 for the trip point for the oil pressure.

Engine Oil Level
Inspect the engine oil level. If necessary, add oil.
If the fault is still apparent, proceed to "Oil Specification".Oil Specification
Make sure that engine oil of the correct specification is used. Refer to the Operation and Maintenance Manual, "Refill Capacities and Recommendations".
If necessary, drain the oil system and refill the oil system with engine oil of the correct specification. Refer to Operation and Maintenance Manual, "Engine Oil and Filter - Change".
If the fault is still apparent, proceed to "Engine Oil Pressure Gauge".Engine Oil Pressure Gauge
Check the actual engine oil pressure with a calibrated test gauge. Compare the oil pressure reading from the electronic service tool to the pressure on the test gauge.
If no difference is noted between the indicated oil pressures, proceed to "Engine Oil Filter".Engine Oil Filter
Remove the engine oil filter. Refer to the Operation and Maintenance Manual, "Engine Oil and Filter - Change".
Inspect the engine oil filter for evidence of blockage.
Install a new engine oil filter. Refer to the Operation and Maintenance Manual, "Engine Oil and Filter - Change".
If the fault is still apparent, proceed to "Engine Oil Cooler".Engine Oil Cooler
If oil flow or coolant flow through the oil cooler is suspected of being low, inspect the oil cooler. Refer to Systems Operation, Testing and Adjusting, "Engine Oil Cooler - Inspect". If there is evidence of
