Component Location 1. Auto light sensor 2. Head lamps 3. Integrated Body Control Unit (IBU) 4. Lighting switch (Auto) 5.
Inspection In the state of IGN1 ON, when the multi function switch module detects auto light switch on, tail lamp relay output and head lamp low relay output are controlled according to auto light sensor's input.
Description The ambient temperature sensor is located at the front of the condenser and detects ambient air temperature. It is a negative type thermistor; resistance will increase with lower temperature, and decrease with higher temperature.
Diagnosis with Diagnostic tool 1. In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (Diagnostic tool). The diagnostic system (Diagnostic tool) provides the following information.
