DTC 02

Solar radiation sensor system inspection

POSSIBLE CAUSE

•  Solar radiation sensor malfunction •  Open circuit in wiring harness between solar radiation sensor connector terminal B and A/C amplifier connector terminal 2I •  Open circuit in wiring harness between solar radiation sensor connector terminal A and A/C amplifier connector terminal 2P •  Short to ground in wiring harness between solar radiation sensor connector terminal B and A/C amplifier connector terminal 2I •  Connector or terminal malfunction

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	INSPECT SOLAR RADIATION SENSOR •  Inspect the solar radiation sensor. (See SOLAR RADIATION SENSOR INSPECTION [FULL-AUTO AIR CONDITIONER].) •  Is it normal?	Yes	Go to the next step.
		No	Replace the solar radiation sensor. (See SOLAR RADIATION SENSOR REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)
2	INSPECT SOLAR RADIATION SENSOR CIRCUIT FOR OPEN CIRCUIT •  Disconnect the A/C amplifier connector (16-pin) and the solar radiation sensor connector. •  Is there continuity between the following terminals of the A/C amplifier connector (16-pin) and the solar radiation sensor connector? ―  2I—B ―  2P—A	Yes	Go to the next step.
		No	Repair the wiring harness.
3	INSPECT SOLAR RADIATION SENSOR CIRCUIT FOR SHORT TO GROUND •  Is there a short circuit to ground in the wiring harness between A/C amplifier connector (16-pin) terminal 2I and solar radiation sensor connector terminal B?	Yes	Repair the wiring harness.
		No	Inspect the connection at the A/C amplifier connector (16-pin).
