DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1A63:11 | Right Solar Sensor: Circuit Short To Ground | This DTC sets when the control module senses lower than expected voltage on the RH sensor feedback circuit, indicating a short to ground. |
| B1A63:15 | Right Solar Sensor: Circuit Short To Battery or Open | This DTC sets when the control module senses higher than expected voltage on the RH sensor feedback circuit, indicating a short to voltage or an open circuit or sensor. |
| B1A64:11 | Left Solar Sensor: Circuit Short To Ground | This DTC sets when the control module senses lower than expected voltage on the LH sensor feedback circuit, indicating a short to ground. |
| B1A64:15 | Left Solar Sensor: Circuit Short To Battery or Open | This DTC sets when the control module senses higher than expected voltage on the LH sensor feedback circuit, indicating a short to voltage or an open circuit or sensor. |
