- •Oil pressure switch failure
- •Water temperature switch failure
- •Charging system failure
- •Low oil pressure safety signal from Oil Pressure Switch
- •High water temperature safety signal from Water Temperature Switch
- •Fault detected by safety shutdown system
- •Fault detected by Oil Pressure Switch
- •Fault detected by Water Temp Switch
- •High engine coolant temperature
- •Overspeed condition
- •Fuel leak triggering the Fuel Leak Detected Switch
- •Faults or damage in the JD Harness or main control box harness
- •Engine fault condition monitored by sensors
- •Oil pressure drops below safe levels
- •Engine coolant overheats
- •Battery charging fault
Suggested Actions
- 1Troubleshoot individual pinouts during circuit testing using harness connector pin configurations (CN1, CN2, CN3, CN4, CN5, CN6, CN7, CN8, CN10, CN11, CN14, CN15)
- 2Use the Connector Arrangement (Wiring View) map (connectors CN1 through CN26) to identify probe points for diagnosis
