Conditions for Clearing the DTC

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2008 GMC Yukon XL, 2008 GMC Yukon, 2008 Chevrolet Tahoe, 2008 Chevrolet Suburban, and 2008 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

A current DTC will clear when the ESCM no longer senses the malfunction and the ignition is cycled ON and OFF.
The DTC will remain in history until 50 ignition cycles have occurred.
