B. Clean the flame detection temperature sensor. Use a nonmetallic cleaning pad to clean the sensor.
Sensor
Result: The components are clean. The flame detection temperature sensor is not damaged. Install the flame detection sensor.
Proceed to Test Step 8.
Result: The flame detection temperature is damaged. Replace flame detection temperature sensor.
Proceed to Test Step 8.
8. Check the ARD for Proper Operation
A. Reset all active codes and clear all logged codes. Use Cat ET to perform an "ARD Ignition Test" in order to verify that the problem is resolved.
The ARD Ignition Test cannot be performed if the DPF soot loading is above 80%. When the DPF soot loading is above 80%, the Manual DPF Regeneration must be performed using Cat ET.
Successful test
Result: The test is successful.
Proceed to Test Step 11.
Result: The test is not successful.
Proceed to Test Step 9.
Result: The test is not successful. There are additional codes.
