Code B1605 RAM Description

The B1605 RAM code indicates a problem with the right solar sensor circuit in the vehicle. Solar sensors are responsible for detecting the intensity of sunlight and adjusting various systems in the vehicle accordingly, such as the automatic headlights, climate control, and more. When the right solar sensor circuit is reading a high voltage, it means that the sensor is detecting an abnormally high level of sunlight, which can lead to incorrect adjustments in the vehicle's systems.
