Series 60 DDEC V Troubleshooting – Section 2.1 Improper Engine Oil Level

Section 2.1
Improper Engine Oil Level

To determine if improper engine oil level is causing low oil pressure, perform the following steps: ‪

1. Ensure that the vehicle is parked on level ground.
2. Check the engine oil level; refer to appropriate service manual, preventive maintenance chapter.
   1. If the engine oil level is correct, check lubricating oil viscosity; refer to "2.2 Improper Lubricating Oil Viscosity" .
   2. If the engine oil level is incorrect, refer to "2.1.1 Low Engine Oil Level Resolution" .

Section 2.1.1
Low Engine Oil Level Resolution

Perform the following steps for low engine oil level:‪

1. Fill engine oil pan to correct level; refer to appropriate service manual, preventive maintenance chapter.
2. Verify low engine oil resolution; refer to "2.1.1.1 Test for Proper Engine Oil Level" .

Section 2.1.1.1
Test for Proper Engine Oil Level

Perform the following steps to determine if properly filled oil pan resolved low oil pressure:‪

1. Install the Diagnostic Data Reader to the vehicles Display Data Line Adaptor, see Figure "Typical Display Data Line Adaptor" ; refer to OEM guidelines.
   

   Figure 1. Typical Display Data Line Adaptor

2. Start and vary engine speed between 1800 - 2100 rpm.
3. Visually examine the DDR for oil pressure reading.
   1. If the DDR indicates oil pressure greater than or equal 241 kPa (35 psi) at 1800 rpm, shut down the engine and disconnect the DDR. No further troubleshooting is required.
   2. If the DDR indicates oil pressure less than 241 kPa (35 psi), at 1800 rpm, shut down the engine and disconnect the DDR. Check lubricating oil viscosity; refer to "2.2 Improper Lubricating Oil Viscosity" .
