GEAR-INPUT 1276329 - Caterpillar

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
