Erasing Trouble Codes Using MIL
WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
Trouble codes can only be manually erased by using DRB. After 50 ignition switch cycles (ON-OFF-ON), PCM memory will erase any trouble codes that have not reoccurred.
