Recommended Actions
Check for diagnostic codes.
Connect Caterpillar Electronic Technician (ET) to the data link connector.
Check for active diagnostic codes and/or logged diagnostic codes. Certain diagnostic codes will limit the engine speed.
Troubleshoot all active diagnostic codes before continuing with this procedure.
Check customer specified parameters.
Verify that the complaint is not normal operation (programmed parameter).
Access the "Configuration" screen on Cat ET.
Check the following parameters:
"Vehicle Speed Limit"
"Lower Gears Engine RPM Limit"
"Intermediate Gears Engine RPM Limit"
"Gear Down Protection Engine RPM Limit"
"Top Engine Limit" engines with software prior to DEC02
"VSL Protection"
"PTO Top Engine Limit" with the PTO on/off switch in the ON position
"PTO Vehicle Speed Limit" with the PTO on/off switch in the ON position
Set each parameter to the parameter's maximum value one at a time and determine whether the problem is corrected.
Check cold mode operation. Note: This is normal operation if the problem occurs only after start-up in cold weather.
Monitor the electronic service tool in order to verify that the engine has progressed from cold mode. "Cold Mode" is indicated in the upper corner of any status screen.
Check the accelerator pedal position sensor.
Use the cruise/idle on/off switch to put the engine in idle mode.
Vary the engine rpm with the set/resume switches. If both of the following conditions are met, monitor the status of the accelerator pedal position sensor.
The engine is stable by using idle mode to control the engine rpm.
The engine is unstable by using the accelerator pedal position sensor.If the status of the accelerator pedal position sensor is unstable, refer to Troubleshooting, "Accelerator Pedal (Throttle) Position Sensor Circuit - Test".
Monitor the vehicle speed signal. Ensure the accuracy of the vehicle speed signal by comparing the vehicle speed signal to the actual vehicle speed. If the vehicle speed is greater than the VSL, the engine rpm is limited to the programmed "VSL Protection". If a problem is discovered, refer to Troubleshooting, "Vehicle Speed and Speedometer Circuit - Test".
Check the fuel supply.
Monitor the exhaust for smoke while the engine is being cranked. If no smoke is present, there may be a problem with the fuel quality or there may be a problem with the fuel supply.
Check the fuel quality. Refer to Operation and Maintenance Manual, SEBU6385, "Caterpillar On-Highway Diesel Truck Engine Fluid Recommendations".
Check the fuel pressure. Refer to Testing and Adjusting, "Fuel System".
Ensure that the fuel system has been primed. Refer to Testing and Adjusting, "Fuel System".
Check for fuel supply lines that are restricted.
Check the fuel filters.
If the temperature is below 0 °C (32 °F), check for solidified fuel (wax).
Check for air in the fuel system. Refer to Testing and Adjusting, "Fuel System".
Check the power train data link. Ensure that the power train data link is not limiting the power.
Monitor the status screen for the power train data link while the vehicle is experiencing problems. If the status screen indicates that the power train data link is limiting the power or the rpm, verify that this is not normal operation. If this is not normal operation, refer to the vehicle's Original Equipment Manufacturer (OEM) for repairs.
Air intake and exhaust system
Clean plugged air filters or replace plugged air filters. Refer to the Operation and Maintenance Manual.
Check the air intake and the exhaust system for restrictions and/or leaks. Refer to Testing and Adjusting for more information.
Diesel particulate filter (if equipped)
Check for active "Warning" or "Alarm" lights that are associated with the diagnostic module for the diesel particulate filter. Refer to Troubleshooting, "Exhaust Particulate Filter Circuit-Test" and Special Instruction, REHS1807, "Installation Guide for Diesel Particulate Filters".
Clean the diesel particulate filter, if necessary. Refer to Special Instruction, REHS1807, "Installation Guide for Diesel Particulate Filters" for more information.
