For 1990-2009 cars only
You may NOT clear a DTC from the memory of the BCM by performing either of the following actions:
| • | Disconnecting the battery |
| • | Disconnecting the BCM electrical connectors |
Perform one of the following steps in order to clear a DTC from the memory of the BCM:
| • | Use the scan tool. |
| • | Perform 100 concurrent ignition cycles without the fault recurring. |
You must clear the DTCs from the BCM after performing a repair. You may also clear the DTCs from the BCM in order to ensure that a malfunction will not occur again. If the fault still exists, the DTC will reset after clearing the DTCs. If any current non-Passlock™ system related DTCs exist, diagnose those DTCs before clearing the Passlock™ DTCs. When the Passlock™ DTCs are cleared, the BCM DTCs will also be cleared.
