New Personality Modules Provide Improved Cruise Control
Usage:
3406B (8TC, 5YG, 2EK) PEEC Truck Engines
Description of Change: New personality modules are available to provide improved cruise control operation. The improved cruise control reduces speed variation when operating with the cruise control activated. The reduced speed variations will minimize driver-throttle interaction and this can help reduce driver fatigue. The improved cruise control will help minimize driver performance variations in a large fleet. Closer control of road speed can improve fuel consumption.
Adaptable To: The chart lists the applicable engine serial numbers, horsepower ratings, and personality module part numbers.
