C7 Engines for Combat and Tactical Vehicles Caterpillar

"Fast Idle Enabled Lamp"

This parameter configures the Engine Control Module (ECM) to turn on a lamp that is connected to output J1/P1:31 or to output J1/P1:21 when fast idle operation is active. To use this feature, a momentary switch must be connected to input 18 (J1/P1:40) and the parameter "Fast Idle RPM #1" must be programmed to a valid speed that is above low idle.

"Wait To Start Lamp"

This parameter configures the ECM to turn on a lamp that is connected to output J1/P1:31 when the air inlet heater is on and the engine is not running. "Fast Idle Enabled Lamp" must be programmed to "J1/P1:21" for this feature to be used.

"PTO Active Output "

The output driver is capable of providing 1.0 Amp when the PTO mode is active. The output is on if the following conditions are met:

• The PTO switch is on.

• PTO mode is active.

• The engine speed is within the programmed limits.

• The vehicle speed is within the programmed limits.

"PTO Switch On Lamp"

This parameter configures the ECM to turn on a lamp that is connected to output J1/P1:30 when the engine is in PTO mode.

"Change Oil Lamp"

This parameter configures the ECM to turn on a lamp that is connected to output J1/P1:30 when the programmed maintenance parameters indicate that an oil change is needed.

"Fan Control Type"

If the ECM is used to operate the cooling fan, this parameter must be programmed to the "On/Off" or to one of the optional parameters. Program this parameter to "None" if the ECM is not connected to the cooling fan relay or the cooling fan solenoid. Also, program this parameter to "None" if the ECM is not operating the cooling fan relay or the cooling fan solenoid.

"Starting Aid Output"

This parameter is used to allow the ECM to determine if conditions are correct for the use of a starting aid (ether).
