Im trying to clear off the ( perform service ) but not sure how to do it . I just did the ccvf an the truck has full deleats no egr or any other emmision garb. My smarty wont clear it an it never showed a code for the service lite.

 

turn key to on position, do not start. press brake peddle twice then press gas peddle twice slowly with in 10 sec. turn key off. start truck. hope this helps.

 

here is the procedure for the CCV and EGR cleaning when the "perform service" light comes on. clearing procedure is there too
