| Inspection |
| 1. |
Ignition "ON" |
| 2. |
Using the scan tool. |
| 3. |
Emit intensive light toward 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.
|
| Replacement |
| 1. |
Disconnect the negative (-) battery terminal. |
| 2. |
With the (-) driver, remove the photo sensor (A) from the center of defrost nozzle.
|
| 3. |
Install in the reverse order of removal. |
Description 1. The photo sensor is located at the center of defrost nozzle. 2. The photo sensor contains a photovoltaic (sensitive to sunlight) diode.
Description 1. 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 temperatures.
Troubleshooting Examples of False-Alarm Occurrence from system characteristics (It’s not a problem) – Characteristics of EM Wave : EM Waves are reflected against all material and especially metal very well. Reflections of EM Waves are varies with the shape of object.
