Diagnostic Aids

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.
