For 1990-2009 cars only
Disconnecting the battery or the BCM connectors will not clear a DTC. Clear a DTC only in one of the following two ways:
| • | Using a scan tool |
| • | The BCM 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.
Clear any history DTC after a system malfunction is corrected in order to prevent future misdiagnosis.
