Troubleshooting
2Fault codes
| Code | Meaning | Cause | Remedy |
|---|---|---|---|
| LOW OIL PRESSURE | The DC control has sensors that continuously monitor the engine for abnormal conditions such as low oil pressure and high coolant temperature. If one of these conditions occur, the control stops the engine. | If low, add oil to bring level up to full mark. Inspect engine exterior for leaks and repair as necessary. Be sure the correct viscosity oil is used for existing ambient temperature (see Maintenance section). The oil pressure switch actuates the fault circuit if pressure drops below 9 psi (62 kPa). | Remove the dipstick and check oil level. If low, add oil to bring level up to full mark. Inspect engine exterior for leaks and repair as necessary. Be sure the correct viscosity oil is used for existing ambient temperature. |
| HIGH COOLANT TEMPERATURE | The coolant temperature switch closes at 250°F (121°C) and actuates the fault circuit. | Check the coolant level in radiator after allowing engine to cool down. Ensure the pump belt is okay and has proper tension.
