B2788-19 on a Nissan vehicle refers to a "Compressor Overcurrent" condition in the air conditioning (A/C) system. This fault code is typically triggered when the A/C compressor draws more electrical current than normal, indicating a possible internal fault within the compressor, such as mechanical seizure or short-circuited windings.

The overcurrent condition may also be caused by wiring issues, a faulty compressor clutch, or a defective A/C control module. When this code appears, the vehicle's A/C system may shut down or operate intermittently to prevent further damage.
