WASHER 6B9126 - Caterpillar

Note: Severe slopes can cause low oil pressure. If the machine is operated on severe slopes, the oil level in the engine crankcase must be at the "FULL" mark on the dipstick. Refer to Operation and Maintenance Manual for details.Use this procedure in order to troubleshoot low engine oil pressure. Use this procedure if one of the following event codes is active. Refer to Troubleshooting, "Event Codes" for information about event codes and the default trip points for these codes. For information on the engine monitoring system, refer to Troubleshooting, "Engine Monitoring System".

Diagnostic Trouble Codes
J1939 Code CDL Code Code Description
(code descriptions may vary) Comments
100-1 E360 (3) Low Engine Oil Pressure Oil pressure is lower than the specified pressure for at least 4 seconds. Engine power is reduced. A snapshot is triggered. The code is logged. Factory passwords are required.
After 30 seconds, the ECM will shut down the engine if the "Engine Monitoring Mode" parameter is programmed to "Shut down".
100-17 E360 (1) Low Engine Oil Pressure Oil pressure is below the specified pressure for at least 8 seconds. A snapshot is triggered. The code is logged. Engine performance is not affected.
100-18 E360 (2) Low Engine Oil Pressure Oil pressure is lower than the specified pressure for at least 4 seconds. Engine power is reduced. A snapshot is triggered. The code is logged. Factory passwords are required.
After 30 seconds, the Engine Control Module (ECM) will shut down the engine if the "Engine Monitoring Mode" parameter is programmed to "Shut down". Probable Causes
Low engine oil level
Aeration in the oil
Low oil viscosity
Plugged Oil Filter
Faulty oil pump
Faulty engine oil pressure sensor
Faulty bypass valve
Damaged suction tube or cracked suction tube
Excessive wear of engine componentsRecommended Actions
Complete the procedure in the order in which the steps are listed.

Troubleshooting Test Steps Values Results
1. Engine Oil Level
A. Check the engine oil level in the crankcase. Refer to the Operation and Maintenance Manual 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
Result: The engine oil level is low.
Repair: Add engine oil in order to obtain the correct engine oil level. Refer to Operation and Maintenance Manual, "Engine Oil"
