Use this procedure to determine that the vehicle wiring and the ECM are functioning properly for the features of the dedicated PTO.The following background information is related to this procedure:Auxiliary Input 1J1/P1-8 (auxiliary input 1) is used for the circuit for the PTO on/off switch when the PTO Configuration is programmed to "Cab Switches", to "Remote Switches", or to "Remote Throttle".When the PTO on/off switch is on, the ECM will be in dedicated PTO mode. If a "Torque Limit" has been programmed, torque will be limited when this circuit is on.If a PTO switch on lamp is connected to the J1/P1-21 (auxiliary output 1), the PTO switch on lamp will turn on whenever the PTO on/off circuit is on.Auxiliary Input 2J1/P1-32 (auxiliary input 2) is used for the PTO set switch when the "PTO Configuration" is programmed to "Remote Switches". The PTO set switch can also be used to increase engine rpm.Auxiliary Input 3J1/P1-31 (auxiliary input 3) is used for the PTO resume switch when the "PTO Configuration" is programmed to "Remote Switches". The PTO resume switch can also be used to decrease engine rpm.The PTO Configuration is Set to Cab Switches.When the "PTO Configuration" is programmed to "Cab Switches" and the PTO on/off switch is on, the following circuits can be used to interrupt a set rpm:
Set/resume switch
Brake/clutch disable switchThe "PTO Configuration" is programmed to "Remote Switches".When the "PTO Configuration" is programmed to "Remote Switches" and the PTO on/off switch is off, the following circuits can be used to interrupt a set rpm:
Set/resume switch
Brake/clutch disable switch

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 cruise 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, "Powertrain Data Link Circuit - 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, "Cruise Control Switch Circuit - 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.     Refer to Troubleshooting, "Cruise Control Switch Circuit - Test".    
"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 Circuit - Test" if a problem with the signal exists.    
"No parameter indicated"     The PTO mode is still active since the ECM has been powered up.     Operate the vehicle in the PTO mode in order to create the problem again.    Test Step 1. Use Cat ET to Check the Programming of the "Dedicated PTO Parameters"
Connect the Cat ET to the data link connector.
Turn the keyswitch 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 - Proceed to Test Step 2.
Noy 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 Wiring for the PTO
From the programming of the parameter for the "PTO Configuration", 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 interlock switches for the PTO.
Contact the installer of the components that are used for the P
