Code B2630 Description

The B2630 diagnostic trouble code (DTC) refers to a Sunload Sensor Malfunction. The sunload sensor is a component of the vehicle's climate control system that measures the intensity of sunlight entering the vehicle. This information is used by the climate control system to adjust the temperature and airflow inside the vehicle to maintain a comfortable environment for the occupants. When the sunload sensor malfunctions, it can lead to inaccurate readings and improper adjustments by the climate control system.
