Normal Operation
Under normal operation, the solar radiation sensor receives a ground through circuit GD115 (BK/GY). A 5-volt reference voltage is supplied to the solar radiation sensor from the electronic automatic temperature control (EATC) module through circuit VH417 (YE/OG) (LH) and circuit VH416 (VT/GY) (RH).

Possible Causes
- An open in circuit GD115 (BK/GY), VH416 (VT/GY) or VH417 (YE/OG)
- A short to ground in circuit VH416 (VT/GY) or VH417 (YE/OG)
- Solar radiation sensor
- EATC module
