| 516 | 5 Volt Sensor DC Power Supply Fault | |
| 517 | 8 Volt Sensor DC Power Supply Fault | |
| 527 | Customer/System Parameter Fault |
| Symptom | Cause | Remedy |
|---|---|---|
| Diagnostic lamp is activated | System detects an active problem | Refer to Troubleshooting, “Electronic Service Tools” for further information. |
| Active codes represent problems that currently exist | These problems should be investigated first. | |
| Logged codes represent intermittent problems, recorded events, and performance history | The problems may have been repaired since the logging of the code. These codes do not indicate that a repair is needed. | |
| Diagnostic lamp illuminates during normal engine operation. | Use electronic service tools to check the active diagnostic codes. | |
| Low oil pressure condition with 'DERATE' selected. | The Electronic Control Module (ECM) will limit the engine power until the problem is corrected. If the oil pressure is within the normal range, the engine may be operated at the rated speed and load. | |
| Active diagnostic code should be investigated. | The cause of the problem should be corrected as soon as possible. If the cause of the active diagnostic code is repaired and there is only one active diagnostic code, the diagnostic lamp will turn off. | |
| Diagnostic lamp illuminates during normal engine operation and shuts off. | An intermittent fault may have occurred. The operator should retrieve the logged fault codes and reference the appropriate information in order to identify the nature of the event. | |
| System configuration parameters affect the emissions or power of the engine. | The electronic service tool is required to alter the configuration parameters. System configuration parameters are programmed at the factory and do not require reprogramming if the ECM software is changed. | |
| Engine speed exceeds 3300 rpm | The event code E190 will be logged. The “DIAGNOSTIC” lamp will indicate a diagnostic fault code. The diagnostic fault code will remain active until the engine speed drops to 2800 rpm. |

| g00687600 | Always use a board or cardboard when you check for a leak. Leaking fluid that is under pressure can penetrate body tissue. Fluid penetration can cause serious injury and possible death. A pin hole leak can cause severe injury. If fluid is injected into your skin, you must get treatment immediately. Seek treatment from a doctor that is familiar with this type of injury. | other_service |
