Load Management Control Mode
When the HVAC controller has a request for rear window defog at idle, the HVAC controller sends a message via UART Serial Data to the
PCM to increase the desired
idle speed. The changes to desired idle speed are as follows. At idle in park/neutral desired idle speed will be at least
1040 RPM. When a gear other than park or neutral is selected, the desired idle speed will be at least
704 RPM.
