CONTROL GP-CONV/AUGER PUMP DR 6R0699 - Caterpillar

this procedure to troubleshoot low oil pressure. Also, use this procedure if one of the following event codes is active or logged.
Table 1
J1939 Code and Description CDL Code and Description Comments
100-1
Engine Oil Pressure : Low - most severe (3) E360 (3)
Engine Oil Pressure The engine is shutdown.
The code is logged.
100-17
Engine Oil Pressure : Low - least severe (1) E360 (1)
Engine Oil Pressure The code is logged.
100-18
Engine Oil Pressure : Low - moderate severity (2) E360 (2)
Engine Oil Pressure The code is logged. If the engine shuts down due to a low oil pressure, power to the Electronic Control Module (ECM) must be cycled before restarting the engine.Probable Causes

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: A code is active or logged.
Proceed to Test Step 2.
2. Check the Engine Oil Level
A. Refer to the Operation and Maintenance Manual, "Engine Oil Level - Check" for calibration of the dipstick gauge. The oil level can possibly be too far below the oil pump supply tube. The oil pump cannot supply enough lubrication to the engine components.
Oil Level
Result: The engine oil level is OK.
Proceed to Test Step 3.
Result: The engine oil level is low.
Repair: Add engine oil to obtain the correct engine oil level. Refer to Operation and Maintenance Manual, "Engine Oil" for the recommendations of engine oil.
Start the engine. Inspect the exterior of the engine for oil leaks.
If the problem is not resolved, proceed to Test Step 3.
3. Check the Engine Oil for Aeration
Note: Foamy oil on the dipstick is a good indication of aeration.
Aeration
Result: The oil is aerated.
Proceed to Test Step 10.
Result: The oil is not aerated.
Proceed to Test Step 4.
4. Ensure that the Engine Oil Viscosity is Correct
A. Obtain an S O S Oil Analysis to determine the characteristics of the oil.
Oil Viscosity
Result: The engine oil viscosity is correct.
Proceed to Test Step 5.
Result: The engine oil viscosity is not correct, or the oil is contaminated.
Repair: Replace the engine oil. Refer to Operation and Maintenance Manual, "Engine Oil" for the recommendations of engine oil.
Repair the cause of any engine oil contamination.
If the problem is not resolved, proceed to Test Step 5.
5. Replace the Oil Filter
Filter
Result: Replace the engine oil filter.
Repair: The oil filter was replaced.
If the problem is not resolved, proceed to Test Step 6.
6. Check the Oil Pump Pressure
A. Manually check the engine oil pressure. Refer to Testing and Adjusting, "Engine Oil Pressure - Test" for additional information.
Oil Pressure
Result: The oil pressure meets specifications.
Proceed to Test Step 7.
Result: The oil pressure does not meet specifications.
Repair: Repair or replace the oil pump.
If the problem is not resolved, proceed to Test Step 7.
7. Check the Engine Oil Pressure Sensor
A. Remove the oil pressure sensor.
B. Install a pipe "T" in the pressure
