DSE-E100

High Coolant Temperature Shutdown

🚨CRITICAL

Engine coolant temperature has exceeded the maximum safe limit and the DSE controller has shut down the engine to prevent thermal damage. This fault will lock out the controller until acknowledged. Do not restart until the cooling system is diagnosed.

🔍 Possible Causes

  • •Low coolant level from leak or evaporation
  • •Radiator blocked with debris
  • •Thermostat stuck closed
  • •Water pump failure
  • •Cooling fan not operating
  • •Temperature sensor failure showing false high

🔧 Troubleshooting Steps

  1. 1Allow engine to cool before inspection
  2. 2Check coolant level in radiator and expansion tank
  3. 3Inspect for visible coolant leaks
  4. 4Clean radiator fins of any debris
  5. 5Verify cooling fan operates when engine is hot
  6. 6Test thermostat opens at correct temperature
