PIN AS 2810898 - Caterpillar

Probable Causes
The probable root causes are listed in order below:
Customer specified parameters (normal operation)
Cold mode operation
PTO on/off switch
Electronic system problem
Fuel supply
Leakage in air-to-air aftercooler core
Air inlet system or exhaust system
Individual malfunctioning cylinder
Torque limit switchRecommended Actions
Perform the following tests in order:
Check customer specified parameters.
Verify that the complaint is not normal operation (programmed parameter).
Connect the electronic service tool.
Check the following parameters:
"Rating Number"
"Top Engine Limit"
"Vehicle Speed Limit"
"Lower Gears Engine RPM Limit"
"Intermediate Gears Engine RPM Limit"
"Gear Down Protction Engine RPM Limit"Note: If the "Rating Number" is programmed to 0, the engine is limited to 119 kW (160 hp).
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.
Connect the electronic service tool.
Monitor the electronic service tool in order to verify that the engine has progressed from cold mode.An active cold mode is indicated in the upper corner of any status screen.
Check the PTO on/off switch.
Verify that the PTO on/off switch is in the OFF position.
Connect the electronic service tool.
Verify that the status for the "PTO On/Off Switch" on the electronic service tool corresponds to the position of the switch.
Cycle the PTO on/off switch while you observe the status screen.
Check for an electronic system problem.
Connect the electronic service tool.
Monitor the "Fuel Position", the "Rated Fuel Limit" and the "FRC Fuel Limit" on the status screen.While the vehicle is operating under full load, the parameters should meet the following conditions:
The "Fuel Position" is equal to the "Rated Fuel Limit".
The "Fuel Position" is less than the "FRC Fuel Limit".If the "Fuel Position" is equal to the "Rated Fuel Limit" and the "Fuel Position" is less than the "FRC Fuel Limit", the Electronics are operating correctly. Go to Step 6.
If the "Fuel Position" is not equal to the "Rated Fuel Limit" and/or the "Fuel Position" is not less than the "FRC Fuel Limit", perform the following tests in order:
Connect the electronic service tool.
When the engine is OFF, turn the ignition key switch to the ON position. Check the status for "Boost Pressure" on the electronic service tool.When the engine is OFF, the boost pressure should be 0 kPa (0 psi).
Monitor the status of the accelerator pedal position sensor. Operate the engine at high idle with the vehicle in Neutral.If the engine can not reach the programmed "Top Engine Limit", check the duty cycle of the accelerator pedal position in order to ensure that the duty cycle is within calibration (75 to 90 Percent at high idle).If the accelerator pedal position is unstable, check the duty cycle of the accelerator pedal position. Check the duty cycle of the accelerator pedal position by slowly operating the accelerator pedal in order to verify that the accelerator pedal position sensor is within calibration. The accelerator pedal position sensor is within calibration when both of the following conditions are met:
10 to 22 percent at low idle
75 to 90 percent at high idleAlso, ensure that the duty
