Conditions for Clearing DTC

WARNING: This page is about a different car, the 2001 GMC Safari and 2001 Chevrolet Astro. However, it is still accessible from the selected car via links, so may be relevant.

A current DTC clears when malfunction is no longer present. A history DTC clears when module ignition cycle counter reaches reset threshold, without a repeat of malfunction.
