Make-Up Tank Oil Level – Low
|
Overview
| CODE | REASON | EFFECT |
| Fault Code: 219 PID: FMI: LAMP: Red SRT: |
Make-Up Tank Oil Level – Low. This fault code is displayed to indicate that the make-up oil tank oil is below specified levels. |
The Centinel™ system will not operate. |
|
Make-Up Tank Oil Level Low Sensor |
 |
Circuit Description
The make-up tank oil level low sensor monitors the oil level in the make-up oil tank and reports to the Centinel™ control module when the oil drops below the specified level.
Component Location
The make-up tank oil level low sensor is located on the lower portion of the front of the Centinel™ system make-up oil tank.
Shop Talk
Verify that the make-up tank has the appropriate level of oil.
Cautions and Warnings
 CAUTION To avoid pin and harness damage, use the following test leads when taking measurements: |
|
CAUTION The component can be damaged internally if dropped. |
|
CAUTION To avoid damaging a new Centinel™ control module, all other active fault codes must be investigated prior to replacing the Centinel™ control module. |
|
CAUTION To avoid pin and harness damage, use the following test leads when taking measurements: |
Troubleshooting Steps
| STEPS | SPECIFICATIONS | |
|---|---|---|
| STEP 1. | Check the make-up tank oil level low sensor. | |
