Cat ET    Meaning or Possible Cause    Troubleshooting    
No Engine Speed     Intermittent engine speed signal or lost engine speed signal.     Refer to Troubleshooting, "Speed/Timing Circuit - Test".    
Switch Turned Off     The PTO On/Off switch is turned OFF or the switch circuit has an open circuit condition.     Proceed with the test procedure.    
Brake     The service brake pedal is depressed or the service brke switch circuit has an open circuit condition.     Refer to Troubleshooting, " Service Brake Pedal Position Switch 1 Circuit - Test".    
Clutch     The clutch pedal is depressed or the clutch pedal switch circuit has an open circuit condition. Also, the switch could be incorrectly adjusted.     Refer to Troubleshooting, "Cutch Pedal Position Switch Circuit - Test".    
Vehicle Speed ? Limit     The Vehicle speed has exceeded the PTO Vehicle Speed Limit or the vehicle speed signal is erratic or intermittent.     Refer to Troubleshooting, "Vehicle Speed Circuit - Test" if a problem with the signal exists.    
Neutral     The transmission is not in neutral or the transmission neutral switch circuit has an open circuit condition.     Refer to Troubleshooting, "Neutral Switch Circuit - Test".    
No Occurrence     The PTO has not been enabled since the ECM has been powered up.     Operate the vehicle in the PTO mode in order to create the problem again.    
Illustration 1 g00644420
This illustration is for the schematic for "cab switches" for "PTO configuration".
Illustration 2 g00644427
This illustration is for the schematic for "remote switches" for "PTO configuration".
Illustration 3 g00644448
This illustration is for the schematic for "remote throttle" for "PTO configuration".Test Step 1. Check the Programming of the Dedicated PTO Customer Parameter
Connect Cat ET to the data link connector.
Turn the ignition key switch to the ON position.
Access the "Dedicated PTO Parameters" on Cat ET. Note the programming of the "PTO Configuration" parameter.Expected Result:The PTO configuration is programmed to either Cab Switches, Remote Switches, or Remote Throttle.Results:
OK - Proceed to Test Step 2.
Not OK - The dedicated PTO features are not programmed for this engine. If PTO operation is desired, the PTO configuration must be programmed to either Cab Switches, Remote Switches, or Remote Throttle. Stop.Test Step 2. Determine the Setup for the PTO
From the programming of the "PTO Configuration" parameter, review the truck wiring in order to determine the method of installation of the wiring. Talk to the driver about the use of the PTO.
Check the cab glove box for any information regarding the installation of the PTO. It is important to understand the location and the function of the PTO Interlocks that are used in the installation.
Contact the installer of the PTO component, if necessary.
Determine the schematic that most closely matches the installation. Review the schematics in this procedure for each of the options for the specific PTO configuration of the truck.
Record the PTO configuration.Expected Result:The requirements for the installation and the application have been reviewed.Results:
OK - Proceed to Test Step 3.Test Step 3. Inspect Electrical Connectors and Wiring
