Clearing Diagnostic Trouble Codes

Clearing DTCs
Disconnecting the battery or the IPC connectors will not clear a DTC. A DTC can only be cleared in one of the following three ways:
1. Using the IPC OBD feature.
2. Using a scan tool.
3. The PC will automatically clear a DTC if the malfunction has not occurred within 50 ignition cycles.

Most all information in diagnostic tables will refer to the scan tool for diagnostic support. For details on using the IPC on-board diagnostic display feature to access and/or clear DTCs. Refer to On-Board Diagnostic System. On-Board Diagnostic System
