Component Locations (1) Fuel Injection pump (2) Secondary fuel filter (3) Rack solenoid (BTM) (4) ECM (5) Timing solenoid (BTM) (6) Fuel transfer pump (7) Primary fuel filter (8) Transducer module (9) Ratings personality moduleThe Programmable Electronic Engine Control III system (PEEC III) was designed in order to provide the following performance characteristics:
electronic governing
automatic air/fuel ratio control
torque rise shaping
injection timing control
system diagnostics
cruise control
vehicle speed limiter
progressive shift engine speed control
pto engine governor
idle shutdown timer
Data LinkThese characteristics provide fuel economy, driver comfort, and serviceability.A full range electronic governor controls the fuel injection pump output in order to maintain the engine rpm that is desired by the PEEC III system.Individual injection pumps meter the fuel. The individual injection pumps pump the fuel under high pressure to the fuel injector nozzle for each cylinder. Electronic timing advance control provides the best fuel injection timing over the full range of engine speed.Starting the Engine
The PEEC III engine may need to crank longer than a mechanically governed engine because some oil pressure is required for the electronic actuator to move the rack. The check engine light should be ON while the engine is cranking. After the engine is started, the check engine light should be ON for no more than 10 seconds. At temperatures below 0 °C (32 °F), starting fluid might need to be sprayed into the air cleaner inlet. If the engine fails to start in 30 seconds, release the starter switch. Allow the starter motor to cool for two minutes before trying to start the engine again.
Excessive ether (starting fluid) can cause piston and ring damage. Use ether for cold weather starting purposes only.
Cold Mode Operation
The PEEC III system automatically idles the engine at 900 to 1000 rpm for the correct warm up time after a cold engine start. The cold mode operation starts when the temperature of the engine is below 5 °C (41 °F). The PEEC III system will reduce the idle speed to the programmed low idle when the engine is warm enough to drive the truck. The PEEC III system considers the engine warm enough to drive when the following conditions are met:
acceptable engine response
vehicle speed of two mph or more
15 minutes of running timeThe engine operating temperature is usually reached before the walk around inspection of the vehicle is completed.
Do not operate the vehicle with the engine in the cold mode condition. If the engine is operated in the cold mode, maximum rpm will be reduced to 1700 rpm and the power will be noticeably reduced.
After cold mode is completed, the truck should be operated at low rpm and low power until normal operating temperature is reached. The engine will reach normal operating temperature faster when the engine is operated low rpm and low power. Typically, the engine should be up to operating temperature by just driving through the yard toward the open road.Manual Fuel Shutoff Lever
A manual shutoff lever is located on the side of the fuel pump. The engine can be shut down
