With Scan Tool

NOTE: Only clear DTC's when instructed to do so. All of the diagnostic data that was saved along with the DTC will also be erased when the code is cleared.

To clear Diagnostic Trouble Codes (DTCs), use the diagnostic scan tool, "clear DTCs" or "clear info" function.

When clearing DTCs follow instructions supplied by the tool manufacturer.

To Clear DTCs From Memory:
^ Use a scan tool (recommended) Or
^ Ignition OFF for at least 10 seconds,
^ Disconnect the negative battery cable for 30 seconds (clears status flags).

Notice: Clearing the PCM DTC memory by disconnecting the battery will clear all PCM memories. Since some operations (particularly IAC valve idle control) are learned, it may be necessary to partially depress the accelerator pedal when re-starting the engine after PCM memory is cleared. It may also be necessary to release the accelerator pedal very slowly when first returning to idle, to prevent a stall. This will allow the PCM to re-learn IAC valve position. Learned operations may be restored by normal driving.
