B1328 CHEVROLET MeaningThe Instrument Panel Module (IPM) monitors ambient light with the left and right sunload sensors. The sunload sensors are an infrared light sensitive photodiode. The IPM supplies 5 volts to the sunload sensors signal circuit and provides a low reference circuit. As the light shining upon the sensor gets brighter, the sensor conductance increases. The sensor signal decreases as the conductance increases. The IPM uses this information to compensate for the effect of the sun on the inside air temperature of the vehicle. The IPM converts the voltage values to count values where one volt is approximately equal to 51 counts.
