About B1576

B1576 is a manufacturer-specific body diagnostic trouble code recorded for Ford vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1576 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B1576 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The B1576 fault code is set by the Body Control Module (BCM) when it detects an open circuit on the lamp park input. This input is the signal wire from the headlight switch or multifunction switch that informs the BCM the operator has selected the park lamp position. The BCM monitors the input continuously and stores B1576 specifically when the wire shows an open condition rather than a short, meaning the expected switched signal is not reaching the BCM at all. With this code active the parking lamps typically fail to illuminate when commanded, and depending on strategy the BCM may default to ...
