Inspection1.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 reduce with lower intensive light.1. Auto light signal2.
Inspection1.Turn the ignition switch OFF.2.Disconnect the temperature control actuator connector.3.Verify that the temperature control actuator operates to the cool position when connecting 12V to terminal 3 and grounding terminal 7.Verify that the temperature control actuator operates to the warm position when connected in reverse.
