Conditions for Clearing the DTC
WARNING: This page is about a different car, the 2002 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
- A current DTC B3033 clears when the BCM detects a valid Passlock™ sensor code.
- When the BCM detects a valid code from the Passlock™ sensor, the ignition switch must be cycled from OFF to ON before this DTC can change from a current DTC to a history DTC.
- A history DTC clears after 100 consecutive ignition cycles if the condition for the malfunction is no longer present.
