With Scan Tool

The SDM will clear the current diagnostic trouble codes, and the SDM will move these trouble codes to a history file under the following conditions:

^ The malfunction is no longer detected
^ The ignition switch is cycled

This does not include DTC B1019, DTC B1025, DTC B1051, and DTC B1053 which are latched codes. You cannot clear a latched code. Additionally DTC B1071 may not clear after you issue a CLEAR CODES command. Repair the malfunction that set the DTC before you replace the SDM.
