The Electronic Control Module (ECM) will automatically provide the correct amount of fuel that is necessary to start the engine. The throttle should not be held while the engine is being cranked. If the engine fails to start in 30 seconds, the starter switch should be released. The motor starter should be allowed to cool for two minutes before being used again. Refer to Operation and Maintenance Manual, "Engine Starting" for more information.
Excessive ether (starting fluid) can cause piston and ring damage. Use ether for cold weather starting purposes only.
Cold Mode Operation
"Cold Start Strategy"The ECM will set the cold start strategy when the coolant temperature is below 18 °C (64 °F).When the cold start strategy is activated, low idle rpm will be increased to 1000 rpm and engine power will be limited.Cold mode operation will be deactivated when any of the following conditions have been met:
Coolant temperature reaches 18 °C (64 °F).
The engine has been running for fourteen minutes.Cold mode operation varies the fuel injection amount for white smoke cleanup. Cold mode operation also varies the timing for white smoke cleanup. The engine operating temperature is usually reached before the walk-around inspection is completed. The engine will idle at the programmed low idle rpm in order to be put in gear.
A machine equipped with this electronically controlled engine should not be moved until it is out of Cold Mode operation.If the machine is operated while in Cold Mode operation power will be noticeably reduced.
After the cold mode is completed, the engine should be operated at low rpm until normal operating temperature is reached. The engine will reach normal operating temperature faster when the engine is operated at low rpm and low power demand."Cool Engine Elevated Idle Strategy"Due to individual applications, your engine may not have the "Cool Engine Elevated Idle Strategy".If the weather is cooler, the ECM may utilize the "Cool Engine Elevated Idle Strategy". This strategy is activated when the following conditions are met:
Engine coolant temperature is less than 70 °C (158 °F).
The parking brake is in the ON position.
The transmission is in the NEUTRAL position.
The throttle switch is set to the LOW IDLE position.If all of the above conditions are met, the ECM will increase the low engine idle to 1100 rpm until one of the conditions is no longer true.Customer Specified Parameters
The engine is capable of being programmed for several customer specified parameters. For a brief explanation of each of the customer specified parameters, see the Troubleshooting Manual for your engine.
