WARNING: This page is about a different car, the 2008 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.

The current DTC clears and will set to history, when the voltage is between 1.47 volts and 2.5 volts for 3 seconds and the ignition is cycled OFF then back to ACC or RUN.
The history DTC will clear after 50 consecutive fault-free ignition cycles have occurred.
