With Scan Tool

Clearing Diagnostic Trouble Codes
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.
When a scan tool is not available, DTCs can also be cleared by disconnecting one of the following sources for at least thirty (30) seconds:

CAUTION: To prevent system damage, the ignition key must be "OFF" when disconnecting or reconnecting battery power.

- The power source to the control module. Examples: fuse, pigtail at battery Control Module connectors etc.
- The negative battery cable. (Disconnecting the negative battery cable may result in the loss of other on-board memory data, such as preset radio tuning).
