Clearing Codes
NOTE:
Codes cannot be erased until DTC memory has been read. Also, if ignition is turned off or engine speed exceeds 2500 RPM after DTC memory has been read, it will be necessary to read DTC memory again before codes can be cleared.
Enter self-diagnostics. See ENTERING SELF-DIAGNOSTICS . Select function "05", ERASE DTC MEMORY. If DTC MEMORY IS ERASED is displayed, press right arrow button until prompted to select another function. If DTC MEMORY HAS NOT BEEN READ is displayed, read DTC memory again. See RETRIEVING CODES . Select function "05" again to erase DTC memory.
