Normal Operation
Under normal operation, the solar radiation sensor receives a ground through circuit 651 (BK/YE). A 5-volt reference voltage is supplied to the solar radiation sensor from the remote climate control (RCC) module through circuit 468 (BN).

Possible Causes
- An open in circuit 651 (BK/YE) or 468 (BN)
- A short together in circuit 651 (BK/YE) and 468 (BN)
- A short to ground in circuit 468 (BN)
- Solar radiation sensor
- Remote climate control (RCC) module
