DescriptionTREAD Lamp– Tire Under Inflation / Leak Warning.1.Turn on condition– When tire pressure is below allowed threshold– When rapid leak is detected by the sensor.
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 auto defogging connector. 3.Verify that the auto defogging actuator operates to the open position when connecting 12V to terminal 3 and grounding terminal 4. Verify that the auto defogging actuator operates to the close position when connected in reverse.
