Clearing Diagnostic Trouble Codes

Disconnecting the battery or the Body Control Module (SBM) connectors will not clear a DTC. A DTC can only be cleared in one of the following two ways:
^ Using a scan tool.
^ The SBM will automatically clear a DTC if the malfunction has not occurred within 50 ignition cycles. Clear any history DTC after a system malfunction is corrected in order to prevent future misdiagnosis.
