Clearing Trouble Codes

Diagnostic trouble codes are retained in memory until erased using the DRB, or automatically erased after 255 key cycles.

NOTE: After repairing all existing Diagnostic Trouble Codes (DTCs), clear and check for any new codes.

1. Connect the Diagnostic Readout Box (DRB), or equivalent scan tool, to the data link connector located under the dash to the right of the steering column.
2. Follow scan tool prompts to erase DTCs. For more information, refer to scan tool operator's manual.
