Information:
Cruise Control On/Off Input Circuit
The cruise control (CC) and power take-off (PTO) ON/OFF input is an ordinary switch. With this switch in the ON position, it is possible to "activate" the cruise control or power take-off mode if other ECM programmed conditions are met.With this switch "open" (or OFF), the input line to the ECM will go to approximately 5 volts. With the switch "closed" (or ON), the input line to the ECM will go to 0 volts (ground).Cruise Control Set/Resume Input Circuit
The cruise control and power take-off set/resume is provided by a three position switch. The switch is used to SET vehicle speed or engine rpm. The function of each position of the switch is as follows:1) CENTER POSITION, the set/resume switch is "open" and all inputs are inactive.2) SET POSITION, after the switch is moved to the SET position and released, the ECM will maintain the existing engine rpm (determining vehicle speed) when the switch was released. If the engine is held in the SET position, the ECM will gradually increase engine rpm (determining vehicle speed) until the switch is released.3) RESUME POSITION, if cruise is deactivated by application of the clutch or service brake, and the switch is then moved to the RESUME position and released, the cruise (PTO) mode is reactivated to the last setting. If the switch is held in the RESUME position, the ECM will gradually decrease engine rpm (determining vehicle speed) until the switch is released.With this switch "open" (or OFF), the input line to the ECM will go to approximately 5 volts. With the switch "closed" (or ON), the input line to the ECM will go to 0 volts (ground).Vehicle Switches Input Circuits
The brake switch is used to deactivate the cruise or PTO modes when the vehicle service brakes are applied. The brake switch is also used to activate the retarder enable output if the service brakes are applied while in cruise mode.The clutch switch is used to deactivate the cruise or PTO modes when the clutch pedal is pressed. The clutch switch is used to DEACTIVATE the retarder enable circuit.With this switch "open" (or OFF), the input line to the ECM will go to approximately 5 volts. With the switch "closed" (or ON), the input line to the ECM will go to 0 volts (ground).Fuel Pressure Input Circuit
Fuel pressure is monitored after the filter by the fuel pressure sensor which is located on the fuel filter housing. The 5 Volt DC operating voltage for this sensor is supplied by the ECM. The output of the fuel pressure sensor is a .5 to 4.5 Volts DC signal. The voltage is dependent upon fuel pressure and is interpreted by the ECM as fuel pressure. If fuel pressure is less than 445 kPa (65 psi) at rated rpm, the "check engine" light is turned on.Engine Electrical System
The electrical system can have three separate circuits: the charging circuit, the starting circuit and the low amperage circuit. Some of the electrical system components are
