2. Inspect the DPF Inlet Temperature Sensor and Wiring
A. Carefully inspect the DPF Inlet temperature sensor wiring for damage.
B. Carefully inspect the DPF Inlet temperature sensor for damage.
   
Damaged wiring or sensor
   
Result: The wiring and sensor are not damaged.
Proceed to Test Step 3.
Result: The wiring and sensor are damaged.
Make the necessary repairs. Proceed to Test Step 3.
   
3. Perform an ARD Ignition Test
A. Connect to Cat ET.
B. Select the Diagnostics tab.
C. Select the Diagnostic Tests tab.
D. Select the ARD Ignition Test tab.
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.
