1. Using a tester, connect the positive (+) lead to solar radiation sensor terminal A, the negative (-) lead to terminal B or C, then measure the resistance. If the resistance is not normal, replace the solar radiation sensor. Resistance except infinity ohms
2. Block the light to the solar radiation sensor, connect the positive (+) lead of a tester to solar radiation sensor terminal B or C and negative (-) lead to terminal A, then measure the resistance. If the resistance is not normal, replace the solar radiation sensor. Resistance infinity ohms (no continuity)
3. Expose the solar radiation sensor to natural sunlight.
4. Using a tester, connect the positive (+) lead to solar radiation sensor terminal B or C, the negative (-) lead to terminal A, then measure the resistance. If the resistance is not normal, replace the solar radiation sensor. Resistance except infinity ohms

Scheme 46

1. Disconnect the negative battery cable.
2. Remove the under cover.
3. Remove in the order indicated in the table.
4. Install in the reverse order of removal.

Scheme 47

1. Measure the temperature around the ambient temperature sensor and measure the resistance between the ambient temperature sensor terminal. If the characteristics of the ambient temperature sensor are not as shown in the graph, replace the ambient temperature sensor.

Scheme 48

1. Disconnect the negative battery cable.
2. Remove the following parts: Dashboard under cover (Driver side) (See «DASHBOARD UNDER COVER REMOVAL/INSTALLATION»(ref-663022-S31534965712014101600000) .) Side wall (See «SIDE WALL REMOVAL/INSTALLATION»(ref-663022-S26910641872014101600000) .) Console panel (LH) (See «CONSOLE PANEL REMOVAL/INSTALLATION»(ref-663022-S28127850752014101600000) .) Hood release lever (See «HOOD LATCH AND RELEASE LEVER REMOVAL/INSTALLATION»(ref-663023-S07470612692014101600000) .) Lower panel (See «LOWER PANEL REMOVAL/INSTALLATION»(ref-663022-S16954671222014101600000) .)
3. Remove the screw.
4. Remove the cabin temperature sensor cover in the direction shown in illustration.
5. Remove the cabin temperature sensor.
6. Install in the reverse order of removal.

Scheme 49

1. Measure the temperature around the cabin temperature sensor and measure the resistance between cabin temperature sensor terminal. If the characteristics of the cabin temperature sensor are not as shown in the graph, replace the cabin temperature sensor.
