Test Step 1. Verify Activation of the PTO Shutdown Timer
Connect the electronic service tool to the data link connector.
Access the Customer Parameters on the electronic service tool. Access the following display screens in order:
"Service"
"Configuration"
Record the programmed PTO shutdown time. The PTO shutdown Time must be between 3 and 1440 minutes. If the PTO shutdown time is programmed to 0, the timer is disabled.
Start the engine. Allow the engine to warm up until the coolant temperature is 38 °C (100 °F). Allow the engine to operate at the programmed low idle and turn off any unnecessary accessory devices.
Ensure that all unnecessary loads are turned off.
Use the following procedure in order to check the operation of the PTO shutdown:
Park the vehicle.
Ensure that the PTO configuration is programmed to "Cab Switches", "Remote Switches" or "Remote Throttle".
Ensure that the status of the PTO on/off switch is on.
Observe the status of the "PTO Shutdown". Expected Result:Result 1 The status of the parameter for "PTO Shutdown" indicates "COUNTING".Result 2 The ECM is not reading the proper conditions for activation of the timer.Results:
Result 1 - The ECM is reading the proper conditions for the activation of the PTO shutdown timer. Proceed to Test Step 2.
Result 2 - Proceed to Test Step 3.Test Step 2. Use the Electronic Service Tool to Verify the Driver Alert Function of the PTO Shutdown
Connect the electronic service tool to the data link connector.
Use the following procedure in order to activate the PTO shutdown timer:
Access the "Customer Parameters" on the electronic service tool. Access the following display screens in order:
"Service"
"Configuration"
Record the programmed PTO shutdown time. The PTO shutdown time must be between 3 and 1440 minutes. If the PTO shutdown time is programmed to 0, the timer is disabled.
Reprogram the PTO shutdown time to 3 minutes for this test.
Observe the following items during the 90 second period before the programmed shutdown time:
Check engine lamp
Status of the PTO shutdown timer
PTO switch on lampDuring the 90 second period before the scheduled shutdown, the status should change from "COUNTING" to "DRIVER ALERT". The check engine lamp and the PTO switch on lamp should flash rapidly.Note: A PTO switch on lamp is an optional feature and the PTO switch on lamp may not be installed.
Reprogram the PTO shutdown timer to the value that was recorded earlier for this test. Expected Result:Result 1 The driver alert function of the PTO shutdown operates in the manner that is described above.Result 2 The PTO switch on lamp did not flash.Result 3 The check engine lamp did not flash.Results:
Result 1 - The PTO shutdown timer is operating properly. Clear all diagnostic codes.STOP
Result 2 - The PTO switch on lamp did not flash during the driver alert.Repair: Perform the following diagnostic procedure: Troubleshooting, "PTO Switch ON Lamp Circuit - Test"STOP
Result 3 - The check engine lamp did not flash during the driver alert.Repair: Perform the following diagnostic procedure:Troubleshooting, "Check Engine Lamp Circuit - Test"STOPTest Step 3. Check the State of the Related Conditions when the Vehicle is Parked
Check the state of the following related conditions when the vehicle is parked:
Ensure that the vehicle speed is 0 km/h (0 mph) on the electronic service tool or the dash display.
Ensure that the engine is not in cold mode. Note: The electronic service tool status screen will indicate if the cold mode is active.
Ensure that the PTO on/off switch is on. Expected Result:Result 1 Vehicle speed is not indicated as 0 km/h (0 mph).Result 2 The electronic service tool status screen indicates that the engine is in the cold mode.Result 3 The PTO on/off switch is not on.Results:
Result 1 - Continue by testing the vehicle speed circuit.Repair: Perform the following diagnostic procedure: Troubleshooting, "Vehicle Speed Circuit - Test"STOP
Result 2 - The engine must not be in cold mode operation while this test procedure is being performed. Allow the engine to run until the coolant temperature exceeds 38 °C (100 °F). Troubleshoot and repair any related conditions. STOP
Result 3 - Continue by testing the circuit for the PTO on/off switch.Repair: Perform the following diagnostic procedure: Troubleshooting, "PTO Switch Circuit - Test"STOP
