Diagnostic Trouble Codes (DTCs) 

Diagnostic  Trouble  Codes  (DTCs)  are  faults  stored  by  vehicle 

computers  when  problems  that  affect  engine  performance  and 

emissions  are  detected.    DTCs  are  used  to  help  identify  the 

cause of a trouble or troubles with a vehicle, and determine the 

fault location(s). 

DTCs  consist  of  a  five-digit  alphanumeric  code.  Please  see 

below for the DTCs format and code types.
