Table For The "PTO Kickout" Status Screen On Cat ET    
Cat ET    Meaning or Possible Cause    Troubleshooting    
"No Engine Speed"     Intermittent engine speed signal or lost engine speed signal.     Refer to Troubleshooting, "Engine Speed - Test".    
"Switch Turned Off"     The PTO on/off switch is turned off or the switch circuit has an open circuit condition.     Proceed with this test procedure.    
"Cruise Control PAUSE Switch"     The cruise control pause switch is depressed or there is an illegal message on the J1939 data link.     Refer to Troubleshooting, "Data Link - Test".    
"Brake Pedal Depressed"     The service brake pedal is depressed or the circuit for the service brake switch has an open circuit condition.     Refer to Troubleshooting, "Speed Control (Auxiliary) - Test".    
"Clutch Pedal Depressed"     The clutch pedal is depressed or the circuit for the clutch pedal position switch has an open circuit condition. Also, the switch could be incorrectly adjusted.    
"Vehicle Speed ≥ Limit"     The vehicle speed has exceeded the speed that is programmed into the "PTO vehicle speed limit" parameter or the vehicle speed signal is erratic or intermittent.     Refer to Troubleshooting, "Vehicle Speed - 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, "Speed Control (Auxiliary) - Test".    
"Not Kicked Out"     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.

Typical circuit schematic for "Cab Switches" configurationThe return wire may be connected to P1-3, P1-5, or P1-18.
Illustration 2 g00644427
Typical circuit schematic for "Remote Switches" configurationThe return wire may be connected to P1-3, P1-5, or P1-18.
Illustration 3 g00644448
Typical circuit schematic for "Remote Throttle" configurationThe return wire may be connected to P1-3, P1-5, or P1-18.Test Step 1. Use Cat ET to Check the Programming of the Parameter "Dedicated PTO Parameters"
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 parameter "PTO Configuration".Expected Result:The "PTO Configuration" is programmed to "Cab Switches", to "Remote Switches", or to "Remote Throttle".Results:
OK - The "PTO Configuration" is programmed. 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 "Cab Switches", to "Remote Switches", or to "Remote Throttle".STOPTest Step 2. Determine the Configuration of the PTO Electrical System
From the programming of the parameter for the "PTO Configuration", review the configuration of the PTO electrical system in order to determine the method of installation of the wiring. Talk to the driver about the operation 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 interlock switches for the PTO.
Contact the installer of the components that are used for the PTO, if necessary.
Determine the schematic that most close
