Clearing Trouble Codes

DTCs in continuous memory can be erased by disconnecting the battery or by ungrounding the Self-Test Input (STI) while the codes are being displayed during KOEO On-Board Diagnostics. The STI is ungrounded by disconnecting the small data link connector or unlatching the Super Star II center button. Always write down the DTCs to avoid losing information that can be used to diagnose the customer concern.
