Note: Engines rated for constant speed use are allowed to complete a starting sequence, an operation at a single constant speed, and a shutdown sequence. Every time the engine is run, each of these operations should occur only once. The starting sequence and shutdown sequence can include a short period of operation at the low idle speed for purposes of warming up and cooling down the engine or driven equipment. The emissions type approval is not valid for operation of a constant speed engine in a manner different from that described above.

Troubleshooting Test Steps Values Results
1. Check for codes
A. Connect Cat® Electronic Technician (ET) to check for active and logged codes.
Codes
Result: There are no active or logged codes.
Proceed to Test Step 2.
Result: There are active or logged codes.
Troubleshoot the active or logged codes.
2. Programmable Parameters
Check the following parameters on Cat ET:
Throttle Position Sensor
Desired Speed Input Configuration
Direct Fuel Control Mode
Note: The engine will have poor performance if the parameters are not programmed correctly.
Parameters
Result: The programmable parameters are OK.
Proceed to Test Step 3
Result: The programmable parameters are NOT OK.
Determine the type of throttle that is used in the application. Program the parameters to match the type of throttle that is used. Refer to Troubleshooting, "Throttle Position Sensor Circuit - Test" for more information.
3. Cold Mode
A. Connect Cat ET to the service tool connector. Verify that the engine has exited cold mode. A status flag will appear if the engine is operating in cold mode. This may limit engine speed.
Cold Mode
Result: The engine is NOT in cold mode.
Proceed to Test Step 4.
Result: The engine is in cold mode.
Take the engine out of cold mode.
4. High Exhaust Temperature
A. The engine may be derated due to high exhaust temperature. Connect Cat ET to the service tool connector. Check for an active engine derate on the status screens.
Note: High exhaust temperature is a calculated value. The engine does not have an exhaust temperature sensor.
Exhaust Temperature
Result: The engine is NOT derated due to high exhaust temperature.
Proceed to Test Step 5.
Result: The engine is in derate due to high exhaust temperature.
Troubleshoot the cause of the high exhaust temperature.
5. Throttle Signal
A. Connect Cat ET to the service tool connector. View the status for the throttle position on the status screen. Operate the throttle from the low idle position to the high idle position. The status should be 0 percent at low idle and the status should be 100 percent at high idle.
Note: Diagnostic codes that are related to the J1939 data link will prevent correct operation of the throttle if the throttle position is transmitted over the data link. If there is a problem with the data link, the engine will remain at low idle until the data link is repaired.
Throttle Signal
Result: The status for the throttle signal is OK.
Proceed to Test Step 6.
Result: The status for the throttle signal is NOT OK.
Refer to "Throttle Position Sensor
