Conditions for Clearing the DTC

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

This DTC requires an ignition cycle in order to change from current to history.
The control module no longer detects an internal memory malfunction (checksum error).
A history DTC will clear after 50 consecutive ignition cycles if the condition for the malfunction is not repeated.
