Conditions for Clearing the DTC

WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

The BCM detects a valid PASS-Key® resistance value when a service replacement BCM is initially programmed for the PASS-Key® system.
A history DTC will clear after 50 consecutive ignition cycles if the condition for the malfunction is no longer present.
Use the instrument panel cluster (IPC) clearing DTCs feature.
Use a scan tool.
