Circuit Diagram
Inspection 1. Turn the ignition switch ON. 2. Connect the GDS. 3. Emit intensive light toward the photo sensor using a lamp, and check the output voltage change. 4. The voltage will rise with higher intensive light and fall with lower intensive light.
Description This system maintains the density of carbon dioxide constantly in vehicle interior by measuring the amount of carbon dioxide to increase the comfortableness and the fuel consumption rate when air conditioning system is operating.
