Solar Sensor: Description and Operation
Heater Mode
The sunload sensor provides the HVAC module software with the amount of sun light entering the passenger compartment through the windshield. A
5-volt reference signal is sent over the driver solar sensor signal to the sensor. The varied reference signal is sent back to the HVAC module software
over the low reference circuit and the right instrument panel junction block.
