## NHTSA's summary

During diagnosis of the exhaust aftertreatment system, the technician may find that the combustion chamber igniter plugs are covered in soot or appear to be excessively worn. If the igniters are dirty or have some wear, this alone does not justify replacement. No service of the igniters is recommended unless an issue with the spark between them is confirmed during a spark test. If, during the spark test the arc between the igniters does not function properly, it is recommended to first clean the igniters, and then check the air gap using the following procedure prior to replacement of the igniters.
