Conditions for Clearing the DTC

WARNING: This page is about a different car, the 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

The current DTC becomes history when the estimated brake rotor temperatures of both drive wheels decreases below 275°C (530°F). The EBCM also enables TCS.
The condition for the DTC is no longer present and you used the scan tool Clear DTC function.
The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.
