6. Clean the Components in the ARD Combustion Head
A. Remove the spark plug (5) from the ARD combustion head.
B. Clean the ground probe inside the ARD combustion head by running a 305-2389 Plug Bore Brush through the hole in the ARD combustion head. Run the brush through the hole several times.
C. Inspect the spark plug. Look for the following problems:
Spark Plug Gap Check the end of the spark plug to make sure that the spark plug gap is within specifications. The gap should be 2.67 0.762 mm (.105 0.030 inch).
Carbon Deposits - Use a nonmetallic cleaning pad to clean the spark plug.
Bent Probe - If the probe appears to be bent, replace the spark plug. Otherwise, install the original spark plug. Refer to the Specifications manual for the correct torque value.
Cracked Porcelain - If the porcelain appears to be cracked, replace the spark plug. Otherwise, install the original spark plug. Refer to the Specifications manual for the correct torque value.
The spark plug may be damaged if the spark plug is dropped. Do not install a spark plug that has been dropped.
Spark Plug Damaged
Result: The components are clean. The spark plug is not damaged.
Repair: Install the spark plug.
Proceed to Test Step 7.
Result: If the spark plug probe is bent, cracked, or has been dropped, replace the spark plug.

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 more codes.
Troubleshoot the additional codes. Refer to Troubleshooting for the correct procedure.
Verify that the problem is resolved.

9. Inspect ARD Swirl Plate
A. Remove ARD head. Refer to Disassembly and Assembly, "Combustion Head Group (ARD) - Remove and Install - Clean Emissions Module" for the proper procedure to remove the ARD combustion head.
Soot accumulation is normal. Slot fouling is defined as more than 1/2 the inner row slots being blocked. Partially blocked inner row slots are normal and do not affect regeneration performance. Refer to Illustrations 6 and 7 to verify if the swirl plate is fouled.
B. Inspect the swirl
