Clearing DTCS

WARNING: This page is about a different car, the 1998 Cadillac Seville. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Disconnecting battery cables or module harness connectors will NOT clear history DTC(s). DTC can only be cleared by using a scan tool or On-Board Service Diagnostic (OBSD). Most diagnostic test procedures will refer to scan tool for diagnostic support. Refer to scan tool manufacturer's instructions.
