Code B2310 RAM Description

The B2310 code indicates a fault within the rear washer switch input circuit, specifically signaling a low voltage condition. This code is primarily associated with vehicles equipped with rear windshield washer systems, which are crucial for maintaining visibility in adverse weather conditions. When the rear washer switch is activated, it sends a signal to the vehicle's body control module (BCM) to activate the rear washer pump. A low input circuit reading suggests that the BCM is not receiving the expected voltage from the switch, which can lead to the rear washer system becoming inoperative.
