Programming – PTO Activates Cooling Fan

If the ECM is being used to run the engine cooling fan circuit, this parameter can be programmed to have the cooling fan cycle normally (based on Coolant Temperature or Inlet Air Temperature or A/C High Pressure) or run continuously when in the Dedicated PTO Mode.

All electronically controlled on-highway engines covered in this handbook


Some applications require the fan to be on continuously during PTO operation. This can be accomplished without additional wiring by programming this parameter.

If the application does not require continuous fan operation but the ECM is programmed to Continuous mode, excessive fuel may be consumed, increasing overall cost of operation.
