Diagnostic Aids

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 GMC Yukon XL, 2015 GMC Yukon, 2015 Chevrolet Tahoe, 2015 Chevrolet Suburban, and 2015 Cadillac Escalade ESV. However, it is still accessible from the selected car via links, so may be relevant.

Use the scan tool to determine the status of the afterblow feature prior to programming. When the module is programmed, the afterblow feature is set to disabled by default.

If the afterblow feature was previously enabled, or is desired, use the scan tool HVAC Control Module Configuration Functions to enable the afterblow feature.
