PROBLEM
When the engine is subject to extreme cold temperatures and extended periods of engine idling with little to no load ice accumulates in the engine air intake manifold on certain C27 Locomotive Engines.
The current freeze protection strategy takes the engine to high idle with out operator notification. This can cause the vehicle to speed up in this application if left in forward/reverse.
There is a new software strategy that has been implemented to mitigate ice formations and prevent the engine from to high idle when in the forward/reverse position.
