Test Step 1. Verify Activation of the "Idle Shutdown Timer"
Connect Cat ET to the data link connector.
Access the "Configuration" screen on Cat ET.
Record the programmed time for the "Idle Shutdown Timer". Note: The "Idle Shutdown Timer" must be between 1 and 1440 minutes. The timer is disabled if the "Idle Shutdown Timer" is programmed to 0.
Record the programmed status of the parameter for the "Allow Idle Shutdown Override" and the "Idle Shutdown Timer Maximum RPM".
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. The "Idle Shutdown Timer Maximum RPM" can be programmed to allow the timer to be reset by increasing the engine rpm above the programmed limit. Ensure that the accelerator is not being depressed so that the rpm increases beyond the programmed limit.
Ensure that the status for "Vehicle Speed" on Cat ET is 0 km/h (0 mph).
Ensure that the engine speed on the status screen is at "Low Idle".
Ensure that the clutch pedal is not depressed. Ensure that the brake pedal is not depressed.
Ensure that the status of the PTO on/off switch is off.
Observe the "Idle Shutdown Status". Expected Result:The "Idle Shutdown Status" indicates "Counting" or the "Idle Shutdown Status" indicates "Not Active".Results:
Counting - The "Idle Shutdown Status" indicates "Counting". The ECM is reading the proper conditions for the activation of the "Idle Shutdown Timer". Proceed to Test Step 2.
Not Active - The "Idle Shutdown Status" indicates "Not Active". The ECM is not reading the proper conditions for activation of the "Idle Shutdown Timer". Proceed to Test Step 3.Test Step 2. Verify the Driver Alert Function for Idle Shutdown and the Override Function for Idle Shutdown
Access the "Configuration" screen on Cat ET.
Reprogram the "Idle Shutdown Timer" to 1 minute for this test.
Observe the following items during the 30 second period before the programmed shutdown time:
Check engine lamp on the vehicle's dash panel
Idle shutdown status on Cat ET
If the "Allow Idle Shutdown Override" parameter is programmed to "YES", perform either of the following actions in order to override the shutdown:
Depress the clutch pedal.
Depress the service brake pedal.Note: This action must be accomplished while the check engine lamp is flashing. The check engine lamp flashes during the 30 second period before the programmed shutdown time. The 90 second Driver Alert period can be tested by programming the "Idle Shutdown Timer" to 2 minutes or longer.
Reprogram the "Idle Shutdown Timer" to the original value. Expected Result:During the 30 to 90 second Driver Alert period before the scheduled shutdown, the status changes from "Counting" to "Driver Alert" and the check engine lamp flashes rapidly. If the "Allow Idle Shutdown Override" is programmed to "YES", the "Idle Shutdown Status" changes to "Override" after the pedals are depressed.Result 1 The "Idle Shutdown Timer" behaves in the manner that is described above.Result 2 The check engine lamp did not flash during the alert.Result 3 The ECM did not detect a change in the status of the service brake.Result 4 The ECM did not detect a change in the status of the clutch.Results:
Result 1 - The "Idle Shutdown Timer" behaves in the manner that is described above.Repair: The "Idle Shutdown Timer" is operating correctly.STOP
Result 2 - The check engine lamp did not flash during the alert.Repair: There may be a problem with the check engine lamp. Refer to Troubleshooting, "Check Engine Lamp Circuit - Test" for information that is related to troubleshooting the circuit for the check engine lamp.STOP
Result 3 - The ECM did not sense a change in the status of the service brake.Repair: There may be a problem with the service brake switch. Refer to Troubleshooting, "Service Brake Pedal Position (Switch 1) Circuit - Test" for information that is related to troubleshooting the circuit for the service brake switch.STOP
Result 4 - The ECM did not sense a change in the status of the clutch.Repair: There may be a problem with the clutch switch. Refer to Troubleshooting, "Clutch Pedal Position Switch Circuit - Test" for information that is related to troubleshooting the circuit for the clutch switch.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 Cat ET and the dash display.
Ensure that the engine is not in cold mode. (The status screen on Cat ET will indicate that "Cold Mode" is "Active" in the corner of the display screen.)
Ensure that the PTO on/off switch is in the OFF position.
Ensure that the engine is at the programmed low idle.Expected Result:Result 1 Vehicle speed is not indicated as 0 km/h (0 mph).Result 2 The status screen on Cat ET indicates that the engine is in cold mode.Result 3 The status of the PTO on/off switch is not "OFF".Result 4 The engine is not at the programmed low idle.Results:
Result 1 - Vehicle speed is not indicated as 0 km/h (0 mph).Repair: There may be a problem with the speedometer circuit. Refer to Troubleshooting, "Vehicle Speed and Speedometer Circuit - Test" for information that is related to troubleshooting the speedometer circuit.STOP
Result 2 - The status screen on Cat ET indicates that the engine is in cold mode.Repair: 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 20 °C (68 °F). Troubleshoot and repair any related conditions.STOP
Result 3 - The status of the PTO on/off switch is not "OFF".Repair: There may be a problem with the PTO switch. Refer to Troubleshooting, "PTO Switch Circuit
