Conditions for Clearing the MIL/DTC

WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

The ABS Indicator may remain illuminated after the DTCs are cleared, until the vehicle is driven at speeds greater than 13 km/h (8 mph) and the self test is completed.
The condition for the DTC is no longer present.
The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.
